UK’s SMEs say ‘apprentices are the solution to UK’s skills gap crisis’ 03/19/2025

UK’s SMEs say ‘apprentices are the solution to UK’s skills gap crisis’ Over 80% of the UK’s SMEs believe apprenticeships are at least partly the solution to the UK’s skills gap crisis, with a further 69% of the view apprenticeships are a ‘valuable alternative to university’ Four in 10 (44%) feel not enough is being done to encourage young people to consider apprenticeships. The findings are taken from the latest independent research commissioned by Close Brothers Asset Finance and are in support of National Apprenticeship Week (NAW), which highlights the positive impact that apprenticeships make on individuals, businesses and the wider economy. According to a survey by the Learning and Work Institute, around 70% of employers reported a skills shortage in their workforce. The Close Brothers Asset Finance research confirms that 50% of business owners are concerned there’s a skills gap in their sector while a further 16% say the issue is regionally based. Over a third (37%) of responding firms report having an apprenticeship scheme of their own, with many (65%) stating that if financial assistance were available from either the government or the private sector to help contribute towards wages and/or training, they would put someone from their company forward to participate in an apprenticeship scheme. The National Apprenticeship Service states that 96% of employers with apprentices have experienced at least one benefit from taking on apprentices, and most can count at least eight benefits. In addition, 74% of employers say that apprentices improved products or service quality, and 78% say that they improved productivity while 73% say that staff morale is improved by having apprentices. Steve Gee, CEO of Close Brothers’ Asset Finance’s Industrial Equipment Division, said: “As a funder of a number of sectors that rely on apprentices, we’ve long seen the need and value of apprenticeship schemes, which encourage new talent into industries that really need them.” “As part of our commitment to the SME community, we’ve been funding an apprenticeship scheme since 2015, in partnership with the University of Sheffield’s Advanced Manufacturing Research Centre (AMRC). Under the scheme, we contribute towards the wages of the apprentices in both the first and second year, with all training costs also covered. “The reality is, it’s not cheap for an SME to invest in apprentices – and its important small business owners see it as an investment and not a cost. Handled correctly, apprenticeships can help an SME flourish and, at the same time, develop the individual apprentice.” “I believe we all have a duty to look at where, as ‘UK PLC’, we need to concentrate our efforts and money. I would strongly encourage firms to support apprentices – we know first-hand what a hugely positive impact they can have.” Nikki Jones, Director of the University of Sheffield AMRC Training Centre said: “At the AMRC Training Centre, we’re transforming lives through apprenticeships. We combine classroom learning and shop floor industrial experience to equip new, young talent with all the skills they need to become the advanced engineers of tomorrow. /episode/index/show/mtdmag/id/35776610

Tooling Intelligence supports ITC at Progressive Apprentice Academy 03/19/2025

Tooling Intelligence supports ITC at Progressive Apprentice Academy Edging closer to its 50th anniversary, the Progressive Technology Group has enjoyed a meteoric rise over the last decade. Founded in 1977, the relocation to larger premises in 2013 was one of the many catalysts for the Newbury company’s decade-long growth. Opening multiple new divisions and branching into new markets, the company now employs more than 250 staff. Among its accolades are many prestigious awards from AMG Petronas and Rolls-Royce, to name a few. However, this pedigree cannot be bought; it is embedded in the company’s culture, with Progressive Technology opening its Apprentice Academy in 2015. In this bedrock for developing the talent of tomorrow, Tooling Intelligence Ltd has just donated a SmartDrawer® vending solution. The impressive Apprentice Academy at Progressive Technology enlisted 18 apprentices as part of its 2024 cohort, and this production line of talent nurturing has contributed significantly to the business’s ongoing success. Aiming to mirror the high-tech manufacturing facilities, the Apprentice Academy has a complete range of technologies, from simple two and 3-axis manual machines to high-end 3 to 5-axis multi-functional machine tools. Three full-time trainers and a classroom with PCs support academic and computer-based training. Part of this progression from apprentice to a skilled engineer in an advanced manufacturing facility includes using high-end cutting tools and the associated inventory management systems. With technical partner Industrial Tooling Corporation (ITC), Tooling Intelligence installed its first vending solution at the ISO:9001 and AS:9100 subcontract outfit in 2014. The success of this first SmartDrawer® system led to a second installation in 2016 and a third in September 2024. The versatile SmartDrawer® system from Tooling Intelligence is a drawer system that is completely configurable to the end user’s requirements. Using smart technology, the SmartDrawer® can dispense single or multiple items with reliable, accurate, and monitored inventory control, giving the end user complete visibility and control of its supply chain. The benefits of the SmartDrawer® were evident at Progressive Technology, and this is why the company rapidly adopted additional systems when shop floor inventory management required them. The SmartDrawer®, which comprises individually locked compartments controlled by a user-friendly touchscreen interface, provides ‘self-serve’ access to consumables, equipment, and cutting tools. This has enabled Progressive Technology to manage, monitor, and control its cutting tool consumption with greater visibility while automatically re-ordering stock to ensure the right tool is always available. With a complete audit trail, the SmartDrawer® provides visibility regarding which employee uses which specific item and where and when it is used. With apprentices destined to enter the advanced production facilities in the future, understanding the inventory management process at the West Berkshire company is essential. This is why Tooling Intelligence has made such a generous contribution. The December 2024 arrival of the SmartDrawer® in the Apprentice Academy was installation number four, with the fifth SmartDrawer® being installed simultaneously on the shop floor of the 24/7 manufacturing site. As part of Tooling Intelligence’s donation, ITC has supported the installation with a selection of regularly used cutting tools for the Apprentice Academy. Included are a complete selection of solid carbide and indexable milling and turning tools. The apprentices now have access to the consumables they require as and when they need them from a single source system. Commenting upon the installation, Tooling Intelligence’s Managing Director, Richard Swaffield, says: “We are delighted to support such a valuable customer in their growth journey over the last 10 years. An industry-leading subcontract manufacturer’s repeat business for over a decade is a testament to how our SmartDrawer® system delivers an inventory management system that is bespoke to the demands of each customer. Since investing in its first SmartDrawer®, Progressive Technology has witnessed cost savings, improved inventory management and control, and complete visibility over what products are used and when. This level of insight is essential for the future of any modern manufacturing business. This is why we have donated a SmartDrawer® to the Apprentice Academy at Progressive – the talent of tomorrow needs a complete understanding of the benefits of effective inventory management as well as the implications of not managing your supply chain.” /episode/index/show/mtdmag/id/35776585

Rebirth of a classic British motorcycle 03/19/2025

Rebirth of a classic British motorcycle The Brough Superior, a classic British motorcycle designed by George Brough in 1919 and manufactured in Nottingham, was of such high quality that it was dubbed the Rolls-Royce of motorcycles. One famous customer, T.E. Lawrence (Lawrence of Arabia), owned eight and died in 1935 from injuries sustained when he crashed number seven. The design was beautiful and practical, and a sidecar was often added. Although the factory closed after the Second World War, enthusiasts have ensured the name survives. In 2004, around 1,000 original Brough Superior motorcycles still existed. The brand is regularly seen in period movies and television series, as well as in classic bike shows, hill climbs, and motor races. In 2014 the Brough Superior brand was purchased by a Jersey-registered corporation, which engaged Thierry Henriette to create a Brough Superior factory in St Jean, Southern France, near the aerospace capital of Toulouse. The factory produces luxury motorcycles at the pinnacle of exclusivity and distinction. Although production is in France, the British design spirit has been maintained through a joint venture with Aston Martin to create the AMB 001 Pro, a limited-edition, high-performance motorcycle. To support the R&D process, bringing in-house the manufacture of some complex prismatic components was necessary. A Hurco VMX42SRTi 5-axis VMC was chosen due to its ability to achieve the accuracy and surface finish required. It can also accept 3D models directly into the proprietary WinMax control, renowned for its suitability for high-mix, low-volume production. Additionally, and most importantly, it enabled the manufacturer to go even further in customising motorcycles for its discerning clientele, offering different machining finishes and engraving possibilities and assuring the impeccable quality of parts. The VMC also supports CNC machining of a new, dual-cylinder, 997cc engine for the AMB 001 Pro, a high-performance, turbocharged, track-only motorcycle born from a collaboration between Aston Martin and Brough Superior. It draws inspiration from Aston Martin’s Valkyrie AMR Pro hypercar, which has a power-to-weight ratio comparable to a Formula One car. Manufactured from solid aluminium billet, the engine is lighter, stiffer and more powerful than in previous Brough Superior bikes. In addition to powering the AMB 001 Pro, it has been engineered to fit perfectly into contemporary versions of the classic Lawrence and Dagger motorcycles. Most metal removal and finishing are completed in a single set-up on the Hurco VMX42SRTi. /episode/index/show/mtdmag/id/35776560

Mastering difficult-to-cut aerospace materials 03/19/2025

Mastering difficult-to-cut aerospace materials Difficult-to-cut materials are defined as engineering materials with significantly lower machinability than typical. These materials are often referred to in shoptalk as ‘hard-to-machine,’ ‘tough-to-cut,’ or even ‘nasty.’ It is important to note that high hardness is not the only characteristic that makes these materials challenging to machine; several other factors contribute to their machining difficulties. Every industrial branch, in one way or another, must deal with such materials. However, the leading consumer of these materials is the aerospace industry. It is in this sector—whether in the production of turbine engines, landing gear components, or primary airframe elements—that difficult-to-cut materials have found their most significant application. In the aerospace industry, the key characteristics of required materials are strength-to-weight ratio, robustness, fatigue life, and resistance to corrosion and hot temperatures. It turns out that materials meeting these characteristics are difficult to machine, posing a serious challenge for production. When speaking about such materials, the following information should be considered: l High-alloy high-strength steel, l Titanium alloys, l Hot temperature superalloys, l Composites. High-strength steels are used in elements subjected to extreme mechanical load, such as landing gear. They are also the primary material for various fasteners. Titanium alloys, with their excellent strength-to-density ratio, high corrosion-proof, and creep resistance, have become the preferred material for producing the main parts of a jet engine’s cold section. These alloys also provide a suitable alternative to steel and stainless steel for weight savings. Hot-temperature superalloys (HTSA), which can maintain their strength in high-temperature environments, are common in the components of a jet engine’s hot section. Composites offer impressive specific strength, helping to decrease an aircraft’s weight and opening new prospects for aerodynamic fairing. In military aviation, composites contribute to improved aircraft’s stealth characteristics. However, machining these materials presents numerous challenges for several reasons. The main challenges are as follows: l High material strength results in significant cutting forces that increase the mechanical load on the cutting tool. l Intensive heat generation and low thermal conductivity of the material (for example, when machining titanium alloys) cause poor heat transfer. This leads to a growing thermal load on the tool and increases the risk of build-up on a cutting edge. l Work hardening of materials (specifically HTSA) increases the strength and hardness of the workpiece surface during cutting, making machining difficult. l The high abrasion factor (when machining composites) intensifies the galling of the tool’s active area. Additionally, other specific material features affect machinability. For example, the ‘springiness’ of titanium alloys contributes to vibration, worsening machining accuracy and surface finish. The inner structure of composites is associated with material delamination during machining. All the mentioned aspects accelerate tool wear and diminish tool life. The trends in the aerospace industry distinctly point to the increased usage of difficult-to-cut materials. This is manifested by introducing new alloys with higher strength and heat-resistance characteristics, the broad application of composites, and the utilisation of hybrid-structure (metal-composite) materials. To meet these challenges, the metalworking industry introduces new cutting strategies based on the impressive capabilities of modern CNC machines and CAM systems. However, the cutting tool is the final link in the entire machining chain, which directly contacts the material and removes its layer during operation. This link is the most ‘conservative’ part of the chain, and its development is slow, often hindering the full utilisation of advanced machines’ capabilities. To overcome the existing difficulties, it is necessary to reduce machining data, which leads to low productivity and increased machining costs. Understandably, every step forward, even a small one, in the tool field can significantly improve machining ‘nasty’ materials. Therefore, the metalworking industry welcomes the latest advances in cutting tools, hoping they will radically change the situation. What are the main requirements for tools intended for efficient machining of tough-to-cut aerospace materials? In brief, they need to be hard, durable, and precise to enable productive machining while ensuring predictable and stable prolonged tool life and the required accuracy level. However, meeting these understandable and reasonable demands requires significant efforts, and even small progress in this direction faces challenges. Every new advance involves serious R&D work and extensive testing. Hence, tool development focuses on the following areas: Cutting material grades. Tool design. A tool’s digital component. The emphasis in cutting materials is on improving hardness, wear resistance, and high-temperature strength. This is achieved by introducing new coatings, particularly those based on nanotechnology, and expanding the use of extra-hard cutting materials like cubic boron nitride (CBN) and ceramics. In tool design, enhancements optimise macro and micro-geometries, such as the cutting edge design and cutting edge preparation, to improve cutting capabilities. Computer modelling, combined with computational dynamics and the impressive possibilities of additive manufacturing (AM), provides new opportunities for shaping flutes, chip gullets, and internal coolant channels. This contributes to better chip evacuation and coolant supply, improving tool performance. A key area is increasing the vibration resistance of the tool through advanced cutting geometry, enhancing the rigidity of the tool structure, and using vibration-damping toolholders. The tool’s digital component includes the digital twin and various software products, which allow for virtual assembly, machining simulation, cutting data selection, tool life estimation, and necessary calculations such as machining power and cutting forces. ISCAR expects that this component will be compatible with data exchange standards to meet the requirements of Smart manufacturing. The noted trends are evident in the new developments from ISCAR, one of the leaders in tool manufacturing, presented within the framework of the latest LOGIQUICK campaign. The company has introduced two new carbide grades with PVD coating: IC1017, which ISCAR created for turning Ni-based HTSA, and IC716, which is intended for high-performance indexable milling titanium alloys. The range of chatter-dampening solid carbide endmills has been expanded with contemporary designs made from the bronze-coloured IC608 carbide grade, which is the first choice for the ISO S group of applications (cutting superalloys and titanium). Another carbide grade, IC5600, has been developed by ISCAR’s prolific R&D Materials Sciences engineers for milling steel (ISO P group). The combination of the grade’s submicron substrate, CVD coating, and post-coating treatment aims to enhance resistance to abrasive wear and thermal loading, increasing cutting speed, particularly when machining high-strength steel. CERAMILL, a new family of endmills with indexable single-sided round inserts (Fig. 1), is interesting from two points of view. First, the family utilises an ingenious mechanism for high-rigidity insert clamping. This mechanism allows for an increased number of teeth compared to a typical design of similar tools in the same diameter. Additionally, it enables simple indexing and insert replacement without removing the endmill from the toolholder. Second, the inserts are produced from ceramic grades specially engineered for machining HTSA. ISCAR has expanded its range of anti-vibration products based on the innovative built-in damping mechanism, which features a heavy mass supported by a rubber spring element containing oil for enhanced dampening. The turning line now includes vibration-absorbing boring bars for machining depths of 12 and 14 times the shank diameter (Fig. 2). Additionally, the milling line has incorporated anti-vibration shanks with MULTI-MASTER adaptation. The QUICK-X-FLUTE is a family of extended flute shell mills developed to achieve high metal removal rates (MRR) in rough milling of challenging materials such as HTSA and titanium (ISO S), austenitic and duplex stainless steel (ISO M), and steel (ISO P). These ‘porcupines’ utilise cost-effective, double-sided square inserts with 8 indexable cutting edges. A key aspect of the mill design is the optimised flute geometry (Fig. 3), which balances mill rigidity and the necessity for adequate chip flow when cutting at high MRR. The QUICK-X-FLUTE mills also feature an inner coolant supply option. Using high-pressure pinpointed coolant with replaceable nozzles and face frontal outlets ensures a direct supply of coolant to the cutting zone. This enhances the cooling and lubrication action, contributing to optimal chip control. Effective coolant supply has become a primary emphasis in contemporary tool designs. In the PICCO line of miniature turning tools, ISCAR has introduced new inserts with internal coolant channels (Fig. 4). In hole making; the company has unveiled new 3-flute solid carbide drills for machining flat-bottom holes featuring three coolant outlets. The latest additions to tool holding include holders with coolant channels along the shank bore. Additionally, in ISCAR’s classical HELIMILL indexable milling family, the company’s R&D engineers have upgraded the design to maximise flow rate with minimal pressure drop using computerised fluid dynamic (CFD) software. Improvements have also been made to NEOITA, an integral part of the company’s digital tool component. NEOITA, an expert system that recommends optimal tooling solutions and forecasts tool life for a specific application, now includes new features. One of these is the AI-powered information search, specifically designed to retrieve detailed data on workpiece materials, including their metallurgical composition and typical uses. Enhanced performance in machining difficult-to-cut aerospace materials is a complex challenge. Tool manufacturers continually strive to provide more advanced and productive solutions to address this. While no radical breakthroughs have been observed, recent developments indicate steady evolutionary progress in this area. /episode/index/show/mtdmag/id/35776240

Kennametal revs up innovation with 3D printed tools 03/19/2025

Kennametal revs up innovation with 3D printed tools Building on the success of their award-winning 3D-printed stator bore tool for electric vehicle machining, Kennametal has developed an innovative 3D-printed transmission housing tool for Voith that cuts weight by approximately 45% and reduces machining time by approximately 50%. As transportation components become increasingly more sophisticated and the requirements more stringent, manufacturers need complex tooling solutions to machine those components. That poses a challenge as the weight of such tooling can become too heavy for efficient operation on machining centres, tool changers and tool magazines. Machine operators may also have difficulty managing the tool. A recent collaboration by Kennametal, an industrial technology leader, and Voith, a leading supplier of drive technologies, shows how 3D printing offers a pathway to novel, lighter-weight tooling solutions that overcome these challenges while improving productivity and efficiency. The Challenge: Machine multiple, tight tolerance, large diameter bores with existing machining centres Voith wanted an innovative solution to optimise its machining processes for transmission housings further. To achieve the required tolerances, the company needed a multi-stage tool capable of machining multiple bores in one operation. The tool also needed to have two effective cutting edges on the main diameters to achieve the specified cycle time. Finally, the tool had to weigh less than 12kg to meet the requirements for tool changing and tilting moment on the toolchain. “Finish machining a large aluminium housing with multiple bores up to 350mm and IT7 tolerance grade is a demanding application,” said Werner Penkert, Manager of Product Engineering. “To machine these large bores with such tight tolerances, we need very rigid tools, which typically means they are heavy weight. When manufactured using conventional methods, a typical tooling solution for this type of application could weigh as much as 25kg, which is too heavy for the existing machines or for an operator working with the tool.” Intrigued by how Kennametal leveraged 3D printing to produce a lighter-weight stator bore tool for electric vehicle machining, the Voith team turned to the industrial technology leader to collaborate on a solution. “Kennametal’s innovative approach with 3D printing excited and inspired us to take this path together,” says Friedrich Oberländer, Director of Production Technology at Voith. The solution As with the stator bore tool, Kennametal leveraged its expertise in metal additive manufacturing—plus the concept of generative design to meet the demanding requirements of Voith’s transmission tool. With conventional subtractive manufacturing, weight is reduced by removing excess material. However, with 3D printing, manufacturers can start with nothing and put material only where it is needed, resulting in lighter-weight, more complex geometries not possible via conventional manufacturing processes. To fully leverage additive manufacturing’s design freedom, Kennametal used generative design, an iterative process that optimises the design of 3D-printed parts to meet an application-specific set of constraints. The generative design process often results in complex, organic shapes reminiscent of natural structures. In the case of the Voith tool, generative design directly addressed machining forces on the tool, enabling Kennametal to design a solution optimised for stability, stiffness, balancing and coolant supply—with a weight of just 11.5kg. Kennametal applied its expertise in additive manufacturing and machining to produce the tool. The tool pockets are precision machined and designed to be used in combination with Kennametal’s proven RIQ inserts technology. “Additive is one tool in our toolbox, but we also applied our deep expertise in precision machining to develop a novel solution that efficiently addresses the challenges of boring deep holes in conjunction with multiple large diameters,” Penkert. The design of Kennametal’s 3D-printed transmission housing tool mimics the organic shapes found in nature, delivering reduced weight and a 50% reduction in machining time for the customer, Voith. The Results: 50% reduction in machining time Working in close collaboration with Voith, Kennametal manufactured a prototype tool and put it to the test in its demonstration centre in Fürth, Germany—part of a global network of test and demonstration centres where the company works with customers to design, iterate and validate machining solutions. This solution was particularly challenging in achieving both manufacturing and part quality requirements. Design simulation, additive manufacturing, and practical tests in the demonstration centre allowed the team to validate the machining results. Voith then conducted the first tests on-site, followed by longer-term tests for series production. Further customer requirements were implemented, and the tool was jointly perfected and finalised. “The Kennametal tool delivered outstanding quality and performance from the first use, achieving a 50% reduction in machining time while still meeting accuracy and surface finish requirements. Additionally, the reduced weight limits the load on the magazine, tool changer and spindle—effectively reducing maintenance costs,” said Oberländer. “Our collaboration with Kennametal clearly shows the enormous innovation potential of additive manufacturing when applied in such a cooperative partnership.” Kennametal Additive Manufacturing (AM) offers a game-changing solution by utilising high-performance materials and parts that are produced faster and with the design flexibility of 3D printing. Kennametal brings nearly a century of materials and manufacturing expertise to every layer of the AM process—from raw material to finished part. This helps customers unlock the full value of 3D pr /episode/index/show/mtdmag/id/35776155

Incentives needed to ease bumpy ride along Electric Avenue 03/19/2025

Incentives needed to ease bumpy ride along Electric Avenue The electrification transition and inflexible EV production quotas are taking a heavy toll on the automotive industry, but buses and commercial vehicles posted their best years since 2008. Will Stirling reports. MTD magazine is unwaveringly positive in its coverage of manufacturing news, but facts are facts: automotive manufacturing is on a downward slide. Combining cars and commercial vehicles (CVs), the UK produced 905,233 units in 2024, -11.8% from 2023, and slipping below the psychologically important one million units mark. Electric vehicles now comprise over one-fifth of all new car registrations, but the EV market contracted by 2.5% to 139,345 units. The bright spots are in the commercial vehicle (CV) and bus markets. Production in the UK rose 4% to 125,649 units, and both buses and CVs have had their best years since 2008. Carmakers face a multitude of challenges to produce both ICE (combustion engine) and EV cars in high volume. Higher energy and material costs, shortage of skilled people and potential tariffs on exports to the US, but the two most significant factors affecting the production of cars are the costly transition to electric and globally softer demand. The government has set onerous targets for the proportion of EVs that car companies make in Britain, from 22% last year to 28% this year – a tall order that experts believe won’t happen – and 80% by 2030, after which the ICE car ban kicks in. The problem is that these targets are running ahead of demand. “The targets were set when demand forecasts were much higher; we know there’ll be a significant shortfall,” says Professor David Bailey, an automotive business expert at the University of Birmingham. “Car firms are going to struggle to shift that volume of cars without very significant discounting, and therefore losses.” He adds: “Our two biggest producers, Nissan and Jaguar Land Rover, will struggle to meet that kind of stretched targets as they get bigger, so they will potentially be fined, and they may well have to buy credits from Chinese all-EV makers who can hit the target. So what a perverse policy that is – that you’re subsidising the Chinese and fining domestic manufacturers.” Electric vehicle production and net zero targets have not been intelligently assessed. The government intends to phase out new petrol and diesel cars by 2030, and although the car industry was invited to consult on this in December 2024, many think the target is too early to hit. “The 2030 ban on ICE policy was plucked out of thin air to try to differentiate the UK from the European Union while signalling to investors that the UK is serious about decarbonisation to encourage investment in the UK. But it hasn’t worked – because Brexit has made the UK less competitive and attractive, because of high energy costs, and it hasn’t worked because we don’t have a proper industrial strategy to support that transition,” David says. The government is now consulting on the industrial strategy, but it should have been firmly embedded in 2025 to help hit the 2030 ICE ban effectively. Stimulate demand; cost of electrification bites Demand for electric vehicles needs to be higher. The government has proposed cheap loans for EVs, but it sounds too complicated for the average car buyer, who wants to know the price, not a complex subsidy and loan. And a VAT break on EVs has been proposed, although this is a pro-tax government. “The government’s problem is that it has boxed itself in agreeing to continue the fiscal rules that the Conservatives put in place, which I think was a bad mistake all along, and that has limited their room for manoeuvre. The industry wants a fiscal incentive for EVs, which could either be an upfront discount if you buy one or a VAT reduction on purchases and charging, to stimulate demand,” Bailey says. Demand for vehicles aside, car production volumes are also lower because factories spend millions of pounds and months retooling their lines for EV manufacture, affecting their ability to produce. Internalisation of component manufacturing Some tier one and smaller suppliers to UK automotive have gone, due partly to the complications and costs of Brexit. GKN Automotive moved its Birmingham factory capacity to Poland in 2021/2022. A lot of smaller companies have been cut out of European supply chains post-Brexit, and several auto suppliers have struggled or gone out of business, unable to cope with the export and reimport bureaucracy when some components may cross the English Channel several times before being assembled here. In addition, several big carmakers are internalising the manufacture of key components as these companies aim to be more vertically integrated. “Partly, this is in reaction to the semiconductor crisis where firms were caught out,” says David Bailey. “For example, Jaguar Land Rover will be making its new electric drive train in-house, probably at the i54 plant. Previously, for internal combustion engine cars, JLR would have bought the drives from GKN Driveline, but it is internalising it. We are seeing that shift broadly as well.” A good example is Nissan’s partnership with battery company AESC, which supplies directly to Sunderland. This year, Nissan is expected to open a new 360m long, 23x football pitch-sized battery gigafactory in Sunderland. When operational, it will employ over 1,000 people and deliver a sixfold increase in UK electric vehicle battery production. The plant is basically an extension of Nissan’s car factory, a tier-one supplier part-owned by Nissan right next door. Pay attention, subbies: Bus bonanza Deliveries of new buses, coaches and minibuses reached a 16-year high in 2024, with 8,390 new units hitting the UK’s roads (total buses produced were higher due to healthy exports). Demand rose across the three main segments: minibuses, single-deckers and double-deckers, with minibuses posting 102.5% year-on-year growth. Zero emission is the main story in buses, and the UK is still Europe’s biggest zero-emission bus market, with deliveries up by more than a third in 2024. As of 2023, Ballymena-based bus manufacturer Wrightbus reported a turnover of £283.4m, a significant 71% increase from £163.3m in 2022. Despite this, profits in 2023 were negative, probably reflecting the big investment in transitioning to net zero powertrains and new tooling. Wrightbus exemplifies the switch to zero emissions. “Alongside our market-leading EV bus, 95% of all buses produced by Wrightbus in Ballymena are now zero emissions – a marked change on 2019, when 95% of all orders were for diesels,” said Jean-Marc Gales, CEO of Wrightbus, when unveiling the new Streetdeck Hydroliner Gen 2.0 hydrogen-powered bus on 20 February. Wrightbus says production will increase to 1,200 this year and then again to 1,400 in 2026 – a record in the company’s proud history of bus manufacture. Dozens of suppliers from across the UK and Europe visited the Wrightbus factory in February to hear how the firm’s continued growth will act as a shot in the arm for the manufacturing sector, with the expected creation of up to 1,000 new supply chain jobs in the next two years. When will car making recover? Industry body The Society of Motor Manufacturers and Traders forecasts vehicle production to fall further in 2025 (cars and light vans to 839,000 units in 2025). Still, it adds that while the EV transition is affecting production, this will be temporary. While the volumes of all electrified technology cars were down 20.4% in 2023, with more than £20 billion worth of investment announced in 2023 and a further £3.5 billion in 2024 to support the UK’s transition, the decline will be temporary; the SMMT stated in February. Car and light van output will increase to circa 930,000 units by 2027, it says. However, potential tariffs from the US are a real threat (second biggest UK car export market), and the lingering cost of living crisis affects EV sales. “Charging at home overnight is cheap but can be 10 times the cost at some public charging points. Plus there is 20 percent VAT at a charging point, but just five percent at home – so the one third of people who have no ability to charge at home will struggle with the transition,” says David Bailey. And while the Dept for Transport has said it is on track to install the target 300,000 charging points by 2030, many people have range and charging speed anxiety, so much more PR is needed to persuade a cash-strapped, conservative public to go electric. /episode/index/show/mtdmag/id/35776025

Working with renowned clients such as Stryker, Boston Scientific, Zimmer Biomet, and Cook Medical, to name a few, the company provides a turnkey service from concept and design through prototyping, machining, and validation of medical components and orthopaedic implants. With over 14 million components manufactured annually, the Irish manufacturer adopts stringent quality measures that are a necessity for ultra-precision medical device parts used in life-saving surgery. Alluding to his role within the company and a background in Smithstown Engineering, Gerard Henn from Smithstown Light Engineering says: “I’ve been here now nearly three years in the role of CEO, and I support the principal director of the business in the running of the operation. Smithtown started in 1974, so we are now 50 years in existence. Our principal area of expertise is precision machining to impeccable quality levels with customer service. We really pride ourselves in supporting the customer in all their difficulties and all their successes.” Manufacturing high precision parts to stringent standards, Gerard alludes to why the County Clare company opted for hyperMILL from OPEN MIND Technologies: “There are so many different options in the marketplace, but OPEN MIND made it much easier for us to work forward with hyperMILL. The explanation of the facets, the features, and how we could optimise our machining strategies and cutting paths – it has everything. That worked in our favour. The relationship with OPEN MIND and its hyperMILL system came together and created a partnership with us.” When Gerard joined the company, one of his aims was to upskill the staff, which was a critical necessity considering the shortage of skilled engineers. Alluding to this, Gerard adds: “OPEN MIND were very enthusiastic and got behind us. They understood what we were trying to achieve, and it’s been a positive relationship all the way through. We’d recommend OPEN MIND to any companies out there who are interested in upskilling their internal workforce – the partnership has been extremely positive.“ Looking closer at the types of work the company is involved in, Gerard continues: “We operate in the medical space, and we support the orthopaedic and medical device companies in Ireland and also globally. We also do instrumentation for procedures, so it’s very much a medical-focused enterprise.” Occupying a large floor area and two facilities, the company is continually evolving. Gerard adds: “So, we have over 200 employees and two sites here in Shannon. The second site is just literally 1 kilometre down the road, so you find us trekking up and down quite a bit, but you see the same technologies and approach in both buildings. We have a third facility in Rzeszów, Poland, a business that’s been operating for 3 to 4 years. We also recently announced a major expansion there.“ “What we find in any process development is you’re going through an iterative process. You’re optimising the machining and cutting process, checking dimensions back to the machine to the virtual CAD station, and bringing all that together. So, I think the fact that OPEN MIND has supported us so much means we have a great understanding of hyperMILL. The upskilling is well in parallel and enables us to bring all the strands together to succeed. By success, I mean that we can deliver parts to specification earlier. That is because that’s what everyone wants. Customers want parts in their hands, and having that collaboration of everyone allows us to achieve that.” /episode/index/show/mtdmag/id/35775990

Fast, versatile machine wins 03/19/2025

Fast, versatile machine wins Michael Phillips, joint owner with partner Wayne Robins of contract machining firm Atomic Precision, describes their recently purchased, Japanese-built Brother Speedio U500Xd1 as ‘a Swiss army knife of 5-axis machining centres.’ His comment is due to the 30-taper machine’s high quality, versatile functionality, compactness, and ability to complete an extensive range of jobs quickly and efficiently. Brother machines are sold and serviced in the UK and Ireland by Whitehouse Machine Tools, Kenilworth. Founded in East Hendred, Oxfordshire, in 2020 by the two time-served mechanical engineering apprentices, who both previously worked in the machine shop at nearby Rutherford Appleton Laboratory’s space development facility, Atomic Precision specialises unsurprisingly in manufacturing components and assemblies for the space and scientific research sectors. Over the next four years, a succession of 40-taper VMCs from another supplier arrived on the shop floor: three 3-axis models and two 5-axis machines. During that time, the subcontractor enjoyed an impressive growth rate of 50% yearly. It was clear to the two partners, who work alone that the ongoing rate of growth was unsustainable without progression on the shop floor to more efficient machine tools and perhaps also automation to gain substantial periods of unattended production. They operate a single-day shift, and working longer hours is not part of their game plan. As a first step to raising productivity, Whitehouse Machine Tools installed and commissioned the high-speed Brother U500Xd1 in September 2024. The partners learned of the machine at the Southern Manufacturing exhibition in Farnborough in early 2023. The order was placed after early hesitation regarding the smaller spindle interface, which later proved to be a non-issue and benchmarking a couple of other 30-taper machines on the market. Mr Phillips commented: “The area taken up on our shop floor by the U500Xd1 is half of the space that one of our 40-taper 5-axis machines occupies, yet the 30-taper VMC produces larger parts. Not only that, but the Speedio finishes an identical component in two-thirds of the time, as the non-cutting elements of cycles are incredibly short, so tools are in-cut for typically 90% of the time during a cycle.” “The linear axes accelerate at 2.2 g up to 56m/min, and chip-to-chip time is 1.3 seconds. Rotary positioning by the trunnion and table is similarly fast, and parts come off complete, resulting in rapid floor-to-floor times.” The machine installed in East Hendred is a well-specified version of the Speedio model, with a 16,000rpm 15kW spindle, 28-position tool turret, high-pressure coolant, and Blum tool and part probing. Axis strokes are 500 by 400 by 300mm, but multi-face machining of components up to 500mm in diameter by 270mm high and weighing up to 100kg is possible owing to the layout of the machining area. As well as producing parts up to the maximum working envelope, the Speedio also machines tiny components requiring complex features cut with a 0.2 mm diameter end mill, hence the decision to opt for the highest speed spindle Brother offers. Towers are extensively used for fixturing multiple smaller parts to extend the walk-away time from the machine if individual cycle times are short. Batch size is usually up to 10-off, although often single prototypes are machined. However, in November 2024, Atomic Precision received a huge order from a new customer for 400-off aluminium brackets requiring a 3+2 machining strategy, using the rotary axes to position the part. The subcontractor could not have accepted the contract if it had been unable to use the elevated speed of the Brother machine. A 5-axis, 40-taper VMC would have been too slow to meet the three-week lead time, so the subcontractor would have had to turn down the work. If more jobs involving quantities of several hundred starts coming in, automating the Brother and other VMCs on-site will go ahead imminently. The factory processes various materials, including aluminium, stainless steel, brass, copper, tungsten, and tantalum. Mr Phillips advises that it is possible to hold ± 10 micron dimensional tolerance ‘comfortably’ on the Speedio, even without climate control in the factory. /episode/index/show/mtdmag/id/35775940

Engineered in record time 03/19/2025

Engineered in record time Engines were already being built at the site in Zafra in 1875, where DEUTZ today has its main factory for processing engine components. Around 500 employees in modern manufacturing facilities produce engine blocks, cylinder blocks, connecting rods, and gears for the Group’s assembly lines in Cologne and Ulm. DEUTZ’s new 3.9-litre diesel engine is mostly used in agricultural and construction machines. It is designed for long service life as an industrial engine and will be built until at least 2035. Series production will start in the coming year after the current prototype phase. Available in a power range from 55 to 160kW, this engine represents an important future project for Deutz with 50,000 units to be produced per year. It is the same size as its 3.6-litre predecessor, so it can be installed in the same vehicles, providing very efficient performance. “Our engines are typically deployed in off-highway applications like agricultural and construction machines, which are in constant use and move heavy loads. We’ll continue to need an internal combustion engine to move those machines. For now, it will be in the form we use today: the diesel engine. Synthetic fuels or hydrogen can considerably prolong their deployment,” explains Alejandro Castilla De La Hoya, Zafra Plant Manager. He points out that the income from this area finances DEUTZ’s investments in the green segment, which is dedicated to the transformation of mobility. The 3.9-litre diesel engine is already set to run on gas or hydrogen in the future. “Based on today’s design, this diesel engine can become a green engine in the long run,” says Manuel Rodríguez López, Industrialisation Manager. This is possible thanks to small modifications, particularly to the cylinder head. However, the engine remains mostly the same. MAPAL is already collaborating on DEUTZ’s first hydrogen engine – a huge 7.8 litres. Two weeks from design freeze to offer “Our clients’ development periods for new parts are becoming shorter and shorter,” explains Thomas Spang, Global Head of Tool Management at MAPAL. This represents a growing challenge for tool manufacturers or complete suppliers like MAPAL. This is true if plans change at the last minute while the deadline for the tool design remains the same. For the engine block of the new 3.9-litre diesel engine, MAPAL only had two weeks after the design freeze to complete a final offer. An ardent team of experts in Aalen completed this ambitious task on time. Well-tuned workflows and many years of experience with the client’s production methods proved advantageous for the team. MAPAL has been conducting tool management for DEUTZ in Spain for 18 years and several projects have been completed together over the years. MAPAL already engineered the machining of the engine blocks for the predecessor 3.6-litre diesel engine, which meant they could draw on practical experience and didn’t have to start from scratch. For example, the tool experts already knew which machines the engine manufacturer had from previous projects. DEUTZ has equipped its assembly line in Zafra with new 5-axis machines over recent years so that they can easily switch to new products. When DEUTZ sent their request, the Tool Management department, in collaboration with the Technology Expert Team (TET) in Aalen, first gave some thought to the production process. “To be quick here, we don’t concern ourselves with detail at this early stage, but instead pull together reference tools and concepts from previously completed projects,” explains Harald Traub from TET. As a project engineer, he is responsible for planning the entire process. “In this way, we can specify an approximate budget and the rough scope of the tool package for the client.” One hundred different tools for an engine block After this rough planning, the concrete tool design followed in the second week. In the end, MAPAL’s offer for the series production of the motor block included almost 100 different tools. Many custom tools achieve short machining times and, thus, high economic efficiency. Aside from these, standard tools are used mainly for milling. A few close-to-standard tools were also used to produce prototypes quickly. Series production can then begin with the optimal set of tools. As part of their original delivery, MAPAL supplied consumable tools as well as the required tool holders and adapters to DEUTZ. All other consumables will be handled by the tool management on-site. From now on, the client no longer pays per tool but per completed part—i.e., the cost per part is billed. The unit costs at first correspond to the price determined during engineering. Certain ratios have been agreed upon for the following years. The client receives an increasing rebate percentage and pays a bit less per unit every year. For this business model to work out, MAPAL has to implement continual improvements to save costs. This is done with new tool technologies and corresponding optimisation. The costs per part are fixed over the contract term, after which a reassessment occurs. Such contracts run over four to five years and offer the client planning security. “With our engineering expertise, we support DEUTZ beyond the tool-setting area and cultivate a close partnership,” Spang highlights. After helping to build the prototype, it is the tool management’s turn to shine on-site during series production. DEUTZ uses approximately 1,300 different tools in total. Thousands of tools are available from stock and must be managed in Zafra. To keep inventory optimal, MAPAL uses its warehouse management systems and digital solutions with the cloud-based software c-Com for tool management. The Digital Tool Management 4.0 doesn’t only handle procurement processes, which are initiated semi-automatically; it also acts as a reporting tool to analyse cost drivers and stocks. Industrialisation Manager Manuel Rodríguez López praises the good collaboration with MAPAL regarding tool management: “Over the course of our cooperation, we have developed extensive technological concepts, which go far beyond mere logistics. Besides achieving cost reductions, tool setting is particularly important for us. The MAPAL employees working on-site have much know-how and ensure that production has exactly the tool they need at the right time.” MAPAL’s tool manager on site is David Castaño. MAPAL also employs tool setters permanently in Zafra. They make sure that a dozen different parts are produced without a hitch. “It is very beneficial to have David here on-site with us,” emphasises Manuel Padilla Fernández, Manufacturing Engineering Manager at DEUTZ. “We can talk about any opportunities for optimisation directly at the machine. We don’t consider David Castaño an external service provider but a part of our team. It’s a very strong cooperation.” Developing together to solve problems If required, new tool solutions can be developed in Aalen via the local MAPAL team. That was the case in Zafra when it became necessary to optimise the tools for machining the bore in the crankshaft and camshaft. A new machining concept from MAPAL with the HPR400 reamer was implemented in cooperation with DEUTZ. David Castaño is convinced of its advantages: “The tool life of the previous tool was 350 units, and resetting was required every 100 units. With the HPR400, we achieve a tool life of 1,000 parts without resetting. The resulting machining quality is exceptionally go /episode/index/show/mtdmag/id/35775840

Automation delivers results 03/19/2025

Automation delivers results Mills CNC has recently supplied Ayrshire Precision, a subcontract specialist based in Ayrshire, with two new SYNERGi systems. The systems, both derivations and highly customised versions of Mills’ standard SYNERGi ‘SPRINT’ solutions, were installed at Ayrshire Precision’s 14,000sq/ft site. In 2023, the first system was retrofitted to a Puma 2600SY lathe, and six months later, the second was retrofitted to a Puma 2100SY. SYNERGi Sprint automation systems are compact, flexible, and cost-effective. Mills’ dedicated automation experts can integrate them with DN Solutions’ lathes, machining centres, and mill-turn machines to create high-productivity automated manufacturing cells. The essential elements of a SYNERGi Sprint system comprise an industrial FANUC robot with varying payloads and reaches, a two- or three-jaw pneumatic gripper, a 900 by 900mm part loading/unloading grid plate, and industrial safety guarding positioned around the system. Mills can also supply customers with multi-socket inserts to optimise each system’s capacity. These are sheet metal fabrications that customers can also choose to manufacture for themselves. Ayrshire Precision serves customers in the oil and gas, subsea, renewables, power generation, and aerospace sectors. It has a well-resourced machine shop and regularly invests in its people, plant and equipment, processes, and systems as part of its ongoing continuous improvement programme. Since 2012, Ayrshire Precision has invested in various Doosan machines, from two-axis and multi-tasking lathes to large-capacity, heavy-duty vertical machining centres and horizontal borers. “We rely on machine tools from Mills. They are powerful, fast and accurate and enable us to meet the highly-regulated, tight-tied up tolerances and exacting surface finishes that characterise a majority of the components we machine,” says Chris Hepburn, Ayrshire Precision’s Managing Director. Ayrshire Precision’s decision to invest in automation was made for several reasons. The volatility of the markets served by the company and, as a consequence, fluctuating customer demand for the company’s machining services, combined with difficulty recruiting and retaining skilled labour, all contributed to Ayrshire Precision’s decision to ‘think outside the box’ and begin its automation journey. “It’s either feast or famine in the markets where we operate. We can either be swamped or, due largely to external macro-economic factors that impact our customers’ business, can experience order cancellations and/or postponements that make it difficult to match our production capabilities and resources with changing customer requirements,” explains Chris Hepburn. Rather than be at the mercy of market forces and to protect the company’s long-term viability and profitability, Ayrshire Precision decided in 2020 to explore new ways to improve its flexibility, performance, and competitiveness. The company’s focus was initially on its small part-turning operation, which, at that time, comprised two Puma lathes, running over two shifts and operated by four staff members. To increase the productivity of its Puma lathes, the company had previously considered integrating a bar feeder into each machine. However, the diameters of the machined drop forged parts, the batch sizes required, and the limited diameter capacity of the bar feeders prevented this approach. Ayrshire Precision discussed its requirements with several automation system suppliers, focusing on the proposed system’s configuration, availability, and cost. As part of its decision-making process, Ayrshire Precision visited Mills CNC, which had previously supplied it with eight Doosan machines. After discussing its plans further with Mills’ automation application specialists and seeing a couple of different SYNERGi systems in action at Mills’ Technology Campus facility in Leamington, it was confirmed that two separate SYNERGi Sprint systems would better meet Ayrshire Precision’s manufacturing requirements. “We liked the design and build of the SYNERGi Sprint system,” remembers Chris Hepburn. “It was simple.” “We asked Mills to put forward their plans and proposals for two SYNERGi Sprint cells – one incorporating our existing Puma 2600SY for larger parts, and the second incorporating our Puma 2100SY for smaller components.” Says Chris Hepburn: “Mills’ approach was responsive and helpful. They worked with us to tailor-make the SYNERGI Sprint systems and offered useful advice. We placed the business with Mills, not just because of their technical and automation expertise, but also because they had originally supplied the two Puma lathes and knew the machines inside out. We also thought that dealing with one supplier for our machine tool and automation system requirements would be easier and would simplify communications, servicing, training, etc.” Ayrshire Precision’s first manufacturing cell was installed in March 2023. The cell comprises a Puma 2600SY multi-tasking lathe and a FANUC 35kg industrial robot with dual Schunk 3-jaw grippers. Other elements include Renishaw probing systems, safety caging, and the system’s HMI control driven by Mills’ proprietary SYNERGi software. With individual part cycle times of approximately 10 minutes, Ayrshire Precision is now benefiting from up to an additional 16 hours of unmanned operation of its Puma 2600SY lathe. Since installation, the company has manufactured different sheet metal pocket inserts to accommodate larger parts and different batch volumes. Ayrshire Precision’s second SYNERGi cell was installed in September 2023. This cell incorporates the Puma 2100SY lathe, a 20kg payload industrial robot and a 900 by 900mm table for processing smaller components. The automation process for both cells involves the robot picking up a workpiece from the grid plate in a programmed sequence and, using the lathes’ auto door opening facility, loading the part into the machine’s main spindle. The door closes to enable the machining of the part’s front end. After all machining operations are finished, the robot picks up the next sequenced workpiece from the table and, in one continuous movement, loads it into the main spindle. Then, it removes the finished part from the sub-spindle and returns it to its designated position on the table. Says Chris Hepburn: “Every time the auto door opens, a completed part is removed from the sub-spindle and a new part is loaded into the main spindle. The process is fast, seamless and continuous. Furthermore, one staff member can operate both cells simultaneously.” With less labour intervention required, Ayrshire Precision’s small part turning operation is now more efficient and profitable. Creating its two cells has also helped free up a couple of its operators, enabling them to be deployed to other machine shop areas. Chris Hepburn concludes: “The investment in our two SYNERGi cells is paying dividends. We have two inherently flexible automated cells that have not only helped us future-proof our small-turned-part operations but have also increased our overall capacity. Although there was initially some anxiety concerning our move towards automated production, the results exceeded our expectations.” /episode/index/show/mtdmag/id/35775790

Aero manufacturer is clear for take-off 03/19/2025

Aero manufacturer is clear for take-off In the aerospace industry, compliance is not just a requirement, but a culture. Senior Aerospace Weston places significant importance on workplace standards—which is why it has installed more than 50 Filtermist oil mist filters. Working primarily with OEMs like Rolls-Royce, Airbus, MTU Engines, Spirit Aerosystems, and many other prestigious clients, Senior Aerospace Weston manufactures a variety of aerofoil and aerostructure components for various platforms in the commercial aviation market. Founded in 1937 and acquired by Senior plc in 2011, the Earby-based manufacturer is now part of an FTSE 250-listed group with over 6,800 employees in 12 countries. As part of a global group in the top echelons of aerospace manufacturing with 3 to 5-axis machining and grinding, CAD/CAM, assembly, NDT, surface treatment, robotic polishing, and much more – achieving standards is critical. Gary Bell from Senior Aerospace Weston says: “Here at Senior Airspace Weston, we believe in maintaining good, orderly, clean standards, housekeeping, and a good working environment. A clean working environment is essential to ensure that we produce our high-specification components.” Providing more detail on the machine shop, Gary adds, “We make a variety of aerospace components for different aircraft programmes and work with a range of materials. This is predominantly aluminium, but we also work with titanium, bronze, nimonic, inconel and steel. We have lots of different types of CNC machining centres with 3, 4, and 5-axis machines. Each machine is specified to manufacture certain types of components, and this is why we have such a wide variety.” With Filtermist extraction units, including the FX6002 and FX7002 on 58 of the company’s machine tools, it is imperative that oil mist is extracted from the machines. As Gary adds: “The type of high-speed machining that we undertake produces oil mist that needs removing from the working environment. Our first thought was to look at the industry-leading standards, and Filtermist was the name that first came up. We engaged with them straight away, and they were extremely helpful in giving us some advice and support. They were able to come on-site and carry out a free survey so that they were able to specify exactly what equipment would be available to support our needs.” With machine tools from leading manufacturers such as Matsuura, DN Solutions via Mills CNC, Grob and Hermle among others on-site, Gary continues: “In total, we have 58 Filtermist extraction units. Some machines require multiple Filtermist units to be installed to ensure the volume is extracted quickly and efficiently. We have a huge variety of machines, and the Filtermist units are flexible enough to accommodate the different types, sizes and requirements of those machines. We have machines that are large in scale, so we needed something that was able to extract from all those different types of scenarios effectively.” Discussing the maintenance requirements and the ongoing relationship with Filtermist, Gary says: “The beauty of the Filtermist system is it’s easily serviceable, so we can specify whether the Filtermist units are standalone or mounted to the equipment. They are easily accessible for the service engineers to come in and replace any components effectively and quickly. The Filtermist units are fitted with F monitors, which are a really easy-to-use system. The operators can see at a glance using the traffic light system whether there are any issues with the effectiveness of the extraction.” Using the globally recognised ‘traffic light’ system of coloured warning lights to alert machine operators when the unit needs servicing, the F Monitor measures velocity pressure to check the airflow through the Filtermist oil mist collector is correct. The Bluetooth-enabled F Monitor 2 measures airflow and time, and the F Monitor 2+ also monitors vibration and motor temperature - making it even easier to identify when the Filtermist unit needs servicing.

A pilot drill that’s up to any challenge 03/19/2025

A pilot drill that’s up to any challenge Manufacturers could only drill on inclined or curved surfaces with pre-chamfering using a milling cutter in the past. Those days are now behind us and you only need one tool - the newly developed WTX Micropilot from CERATIZIT. It can even pull off 90° countersinks at the bore entry in a single operation —saving tool changes, cycle time and costs. Micro machining has rules and practices that are different to everyday machining. Simply put, what works well with standard tool dimensions does not necessarily hold true with small diameters. “To this end, we have revised our micro drilling program and developed a genuine time saver. The WTX - Micropilot is small in stature, but big in performance. Perfectly matched to our WTX - Micro micro drill from 8xD to 30xD, the pilot drill is used at drilling depths of up to 2.5xD,” says Manuel Keller, Product Manager at CERATIZIT. When faults occur in complex, micro-sized components, they quickly end up dumped in the recycling can. The truth is that a number of things can go wrong. Drills can run off, drill holes get crooked or tools break—including damage to the workpiece itself. “Efficient machining of small components presents its own set of challenges,” says Manuel Keller. “Our customers want process reliability, the shortest possible machining times and demand extremely high-quality standards. Fortunately, our WTX - Micro series is up to the task.” Thanks to its ingenious face geometry with a 160°-point angle, the tool ensures the follow-up drill can plunge in cleanly and without running. And with the special Dragonskin coating, clean chip removal and a longer tool life are guaranteed. The WTX - Micropilot is developed from the latest technologies from the substrate to the geometry to the coating. It is also perfectly designed to work together with its ‘best buddy’ WTX – Micro. This drill duo can handle the most common as well as the most demanding tasks. “One special feature of the WTX – Micropilot is that it circumvents the usual mirroring required if drilling inclined and curved surfaces with an inclination of up to 50. This eliminates one processing step, saving time and tool changes. When piloting on straight surfaces, a 90° countersink at the bore entry is also possible,” reveals Manuel Keller. What all WTX micro drills have in common is their special pointing. This maximises positioning accuracy and excellent centring properties. Their lapped surfaces and the patented chip space grinding also guarantee safe and fast chip removal. Additionally, the spiral internal cooling channels of the WTX Micro drill have been optimised to ensure maximum flow of cooling lubricant, which, in turn, secures improved surface quality of the holes. Among other things, this is thanks to a power chamber, which is fitted to the micro drills from 5xD over the entire shank length, which increases the amount of coolant at the tip while maintaining uniform pressure—thus improving tool life. Made for maximum precision With its micro-tool portfolio, CERATIZIT covers most micro-machining applications with high-quality solutions. “This also applies to the WTX - Micro product range, including the new WTX - Micropilot, which makes the impossible possible. On both inclined or curved surfaces with an inclination of up to 50°, there is no need for prior mirroring. And if 90° countersinks are required at the bore entry point on straight surfaces, WTX - Micropilot can easily handle the task in a single operation, saving tool changes, time and costs—without sacrificing quality,” says Manuel Keller. /episode/index/show/mtdmag/id/35775405

Efficient milling 01/29/2025

Efficient milling Milling is a fundamental process that shapes everything from complex aerospace components to critical automotive parts. But despite its ubiquity, successful milling hinges on some careful considerations. How can manufacturers consistently achieve high accuracy, impeccable surface finishes, and cost-effective results? Barry Cahoon, Product Solution Specialist Rotating Indexable—Europe at Sandvik Coromant, offers his advice. Achieving optimal milling results necessitates selecting cutting tools specifically engineered to meet precise machining requirements. This must consider factors such as cutting geometry, material hardness, and machining strategies. Whether the task involves high-precision shoulder milling, high-speed face milling, or complex multi-axis contouring, the tool’s performance directly influences the efficiency and accuracy of the entire process. What defines successful milling? Precision is paramount for any milling operation to be considered successful. Achieving tight dimensional tolerances and geometric accuracy is essential. Surface finish is another critical factor. A smooth, clean finish is not just an aesthetic requirement but often a functional one. In industries such as aerospace, where components such as turbine blades or compressor casings must meet stringent performance standards, even slight deviations in surface quality can lead to major problems. Efficiency also comes into play. Milling processes need to maximise material removal rates while keeping machining time to a minimum, all without compromising quality. Then there’s the question of tool life. Manufacturers constantly seek ways to extend tool life, reduce tool changes, minimise downtime, and ultimately cut costs. However, tool life is closely linked to chip control and cutting forces. Poor chip evacuation or excessive force can cause rapid tool wear, reducing efficiency and producing suboptimal results. Tool selection With so many variables, selecting the right tool is often the biggest challenge. Different operations — such as shoulder, face, or high-feed milling — demand tools with specific geometries and cutting capabilities. Accuracy and precision are the foundation of every milling process. From creating flat surfaces to machining 90-degree shoulders or complex contours, precision is non-negotiable. Proper tool path control, optimised cutting parameters, and stable machine dynamics are all essential to ensure that dimensional tolerances are met. Thanks to their true 90-degree shoulder capability, tools like CoroMill® MS60 deliver reliable performance, particularly for shoulder milling. Efficiency and cost-effectiveness are key considerations in any manufacturing environment. Time saved on machining processes translates directly to reduced costs, making it essential to minimise cycle times without sacrificing quality. In this regard, CoroMill® MH20, specifically designed for lightweight milling, offers excellent performance in operations where high-speed material removal is required. Its insert design reduces cutting forces, allowing for faster feed rates while maintaining tool stability, particularly in deep cavity and pocketing applications. This increases machining speed and extends tool life, reducing the need for frequent tool changes and lowering overall production costs. Chip control and cutting forces are often underestimated but profoundly impact the milling process. Efficient chip evacuation prevents heat buildup and ensures a clean cut, especially in applications involving deep cavities or pockets. Insufficient chip control can cause chips to re-cut, leading to poor surface finish and faster tool wear. Modern tool geometries are designed to optimise chip flow, reducing the risk of clogging and improving overall tool longevity. CoroMill® MF80 offers smooth chip flow and minimal cutting forces, making it highly reliable for roughing and finishing operations. Its ability to handle various materials and machining conditions enhances versatility and productivity across multiple applications. Finally, precision and reliability are non-negotiable when selecting tools for demanding materials such as ISO M and ISO S. CoroMill® MS20, Sandvik Coromant’s new 90-degree shoulder milling solution, delivers exceptional edge-line security and dimensional accuracy. This ensures high productivity and consistent results, even in challenging aerospace and oil and gas applications. Successful milling hinges on a deep understanding of the interplay between tool design, material properties and machining parameters. By carefully selecting tools that are purpose-built for the task at hand — whether that’s shoulder milling with high precision or high-speed face milling for rapid material removal —manufacturers can achieve their goals of improved productivity, lower costs and exceptional part quality. The balance between accuracy, efficiency, tool life and chip control ultimately defines a successful milling operation. /episode/index/show/mtdmag/id/35062705

It's all about collaboration 01/27/2025

It's all about collaboration On the 27th and 28th of November, Hexagon Manufacturing Intelligence invited MTD magazine to the official opening of its new Experience Centre in Holland. Located at the Brainport Industries Campus in the Northwest of Eindhoven, the two-day event was an opportunity to tour the new campus and participate in insightful presentations that demonstrated how Hexagon is driving innovation and, as a result, developing successful industrial partnerships. Eindhoven is responsible for the Philishave, the automatic gearbox, the cassette tape and the compact disc. To foster this culture of innovation for future generations, the Dutch government funded the Brainport Industries Campus, which broke ground in 2017. At around 100,000sq/m, the innovation centre is virtually fully subscribed, and that is why construction of a 225,000sq/m phase two on the 17-hectare site will commence this year. With dozens of high-tech businesses collaborating at the campus, Hexagon is alongside cutting-edge companies with brands like Siemens and Meta (Facebook), just a few located at the facility. MTD magazine attended and the itinerary for the innovation extravaganza promised an exciting lineup. The event started with a welcome from Jan Klingen, Vice President EMEA North, and Eric Veurink, Brainport Industries Campus Director, and a facility tour. As expected with a Hexagon LIVE event, the breadth and depth of technology and insights were so expansive that delegates could choose the most relevant content for their business. Exemplifying this was one of the first panel discussions on the ‘Future of Mobility in Aerospace and Automotive’, hosted by Hexagon Senior Director for Industry Solutions, Johannes Mann, who was joined by speakers Rob van Loon, Additive Manufacturing Manager at KMWE and Thom Grobben, the Vice President of the Technology Hub at KLM Royal Dutch Airlines. The discussion flowed through the challenges of accelerating innovation and agility in the automotive sector to deliver the next generation of smart, connected vehicles. This conversation then moved on to the aerospace industry’s challenges in redefining aircraft architecture and propulsion systems to become more sustainable. Other prominent seminars discussed ‘The challenges in production and collaboration’, ‘Extending asset lifecycles and improving productivity with HxGN EAM’, ‘Surfing the future now’ and ‘Innovation beyond silos: Transforming Manufacturing through connectivity, collaboration, and Cloud/AI’. There was a lot more on show, with panel discussions, presentations, workshops and roundtable debates encompassing every industry sector. Nowhere was this more prominent than in Morgan Maia’s presentation, the Partnership Manager at Oracle Red Bull Racing. Hexagon has partnered with the F1 team since its inception. Flying in from the F1 Teams’ weekend win in Las Vegas, Morgan discussed how Hexagon supports the team in streamlining performance by ensuring compliance with FIA regulations, precision manufacturing, and ensuring the team ‘gets it right first time’. More than just a soundbite, Mike Hughes, Head of Quality Assurance and Manufacturing Engineering at Oracle Red Bull Racing, qualified the support of Hexagon with a statement: “With Hexagon’s help, we’ve managed to reduce our faults by 50% over the last two years.” Morgan’s presentation alluded to how Hexagon is involved throughout the process chain, from 3D CAD modelling and CFD simulations in the virtual wind tunnel to simulation and physical wind tunnel testing. With over one million components handled throughout the season, Oracle Red Bull Racing combines exceptional hardware with efficient software and digital twins to deliver rapid inspection rates. The team has four QA departments encompassing mechanical, external, composites, and race support. They all utilise Hexagon tools, from CAM software to 3D scanners, laser trackers, portable measuring arms and CMMs. The Leica AT960 scanner is a core element of the trackside equipment that improves accuracy and holistic measurement. Its custom orientation enables measurement from different perspectives. For legality checks, Oracle Red Bull Racing uses the AS1 scanner to scan the floor, front, and rear wings to extract key points of the car for performance set-up. With the arrival of Red Bull’s first road car, the RB17, and the opening of its 5,000sq/ft powertrain manufacturing site in Milton Keynes, Red Bull’s number of components produced is set to expand significantly, as will its relationship with Hexagon. The F1 car continually undergoes design cycles that follow the same structured path. With up to 100 projects in-cycle at any time, around 1,000 design cycles are completed yearly. It starts with developing a 3D CAD model and the subsequent digital twin, which is the foundation block for everything that comes after. With CFD, prototypes and a whole raft of processes before the team gets to a finished car, Morgan said: “When you work on a car in the factory and then take it to the track, if there is an issue in manufacturing – it’s too late to do anything about it. We must be sure the car is 100% correct before shipping it. That is why we need Hexagon: to ensure that everything leaving the factory is perfect for when it arrives at the track. We have thousands of parts that need to fit together perfectly. We work to the micron. It’s precision you would see in a high-end watch – but not typically in a 5m long vehicle.” A presentation on Hexagon’s Nexus suite by Stephen Graham, Executive Vice President and GM of Nexus at Hexagon, followed this. Stephen explained: “Nexus is our cloud-based manufacturing platform. We initially conceived it to solve an internal problem. We have acquired over 150 companies in more than 25 years, which has helped us build this portfolio of technologies throughout the product life-cycle. Our challenge is a large portfolio of technology solutions that were never really intended to work together. We wanted to offer our customers a solution to join the dots and bring the next level of value with the technologies all being under one roof. Nexus was conceived to solve this problem of connectivity. As soon as we took the proposition to our customers, we found they had the same problem. Over decades, they had purchased different technologies to solve different problems.” “Nexus directly solves that problem, and what we have found in the last few months is an ability to connect to different technologies from different vendors - it doesn’t just have to be Hexagon products. Since starting development, we have found that businesses are structured very hierarchically, with different disciplines arranged in different silos. The whole thing is very process-driven, and as we try to push the boundaries of manufacturing, this becomes a barrier to succeeding. The need to drive collaboration horizontally across an organisation is coming to the fore as a challenge that needs to be faced.” To demonstrate this, Stephen provided a slide show showing a reverse-engineered workflow using 10 products from Hexagon that facilitate different elements of a product’s lifecycle. The demonstration alluded to new cloud-native apps, technologies and solutions connected to products in the portfolio for decades, such as PC-DMIS. Nexus creates an end-to-end solution that connects the dots. Stephen added: “Once these collaborative workflows have been strung together, engineers can work collaboratively. This provides the opportunity to bring automated and AI technologies into the workflow as automated collaborators in the workflow. A great example of this is ProPlanAI, which we just launched. This large NAPA language model provides precise engineering answers for CAM engineers who may be programming CNC machines. It automatically collates data and generates a G-Code to drive machines on the shop floor. This gives engineers superpowers to drive productivity to the next level.” Hexagon claims that ProPlan AI cuts the time to program machine tools by 75%. The new AI technology enables machine shops to achieve operational excellence at scale, powered by Microsoft Azure services built into Hexagon’s cloud-based Nexus connectivity platform. Available in Q1 2025, ProPlanAI will ‘learn’ from the data created by a company’s CAM programmers. This will enable manufacturers to automatically explore existing programming information to predict ideal outcomes tailored to a company’s preferences, production capabilities, and needs. ProPlanAI will continuously learn and adapt, ensuring programs are as efficient and productive as possible. ProPlanAI can be trained with a company’s institutional knowledge to ensure machines can be quickly and efficiently programmed to their quality standards. Additionally, a Hexagon Copilot provides suggested pathways to advise on best practices without leaving their CAM software. The innovation has been developed in collaboration with Microsoft, and Ygal Levy, the EMEA Manufacturing Managing Director at Microsoft, discussed the company’s strategic partnership with Hexagon in greater detail during an afternoon presentation on the ‘Transformation of manufacturing through Connectivity, Collaboration and Cloud/AI’. Clare Barclay, President of Enterprise and Industry at Microsoft EMEA, said: “Microsoft’s collaboration with Hexagon is driven by a shared belief that we can transform manufacturing productivity. It’s rewarding for us to see how the AI capabilities provided by Azure are empowering CNC programmers with productivity-boosting automation while helping new users upskill faster. This is exactly the sort of transformation AI can bring to the industry, and we are excited to see Hexagon apply its manufacturing expertise to transform workplace productivity.” Verifying the Solution Just over a year ago, MTD magazine visited RODIN Machining. A few miles north of Amsterdam, the start-up company set out to develop an autonomous factory. Incorporating FASTEMS automation, robot-loaded Mazak machines, and integrated innovations that made the mind boggle, RODIN has been a beta-test customer, putting ProPlanAI through its paces before market introduction. Paul Mooij, Director of Digital at RODIN Machining, said: “Machine tool programming is complicated to automate and requires experience. ProPlanAI is exciting because we can leverage our human capital for greater machine utilisation. Our team can program machines in a fraction of the time by applying their valued skills in supervising ProPlanAI suggestions and finalising the programme specifics.” Paul added: “We have built an autonomous factory but are limited by the engineering input we can put into it. This boils down to a race for talent, and we all know it isn’t easy to get good people. We have been working with Hexagon on the development of ProPlanAI, looking at how can we fill it with our data and train it with our models, our machines, tools and our way of working - providing a suggestion of how the model thinks our way of working should be. We can then position our engineer to supervise and undertake ‘prompt engineering’. ProPlanAI is very powerful and provides the right context for the features, model, machines, and tooling available. Using the given context, it then decides, ‘I think you should use these processes for this machining operation’’.” “This has become powerful, and we are progressing rapidly to make big savings. We are leveraging our human capital to achieve more by using AI to provide suggestions. Then, our engineers decide whether to accept the suggestion and proceed or refine the process. For example, we may have a 2D PDF drawing that needs to meet specific tolerances, and ProPlanAI may not know this – and this is the experience we can add to the system. It’s been a fantastic collaboration, and the system continually evolves.” Discussing the current situation, Paul told MTD magazine: “Our engineers will consider how they approach a job and create the CAM file in Esprit. We then feed our models to our developers. Over the last 18 months, we have been feeding the data to ProPlan AI, which uses our approach, machining strategies, cutting tools, machines, characteristics and experience. ProPlan AI creates suggestions for the next job and pre-populates our program, so our engineers are validating and refining the suggestions to meet our specifications. It amplifies the output of our staff.” “For example, if we have an aluminium job that needs a threaded hole with a chamfer, we would have a unique way of doing that with our machines and tools in our CAM files. Based on those patterns, the model learns our strategies and recognises the parameters for a threaded hole in aluminium, the feeds, speeds and so on.” Looking at benefits during testing, Paul adds: “It is amplifying our output and boosting our efficiency. At present, the savings are impressive. We continuously add data to our ProPlanAI suite, so the savings will cascade into ever greater efficiencies as we progress.” /episode/index/show/mtdmag/id/35025235

Drill sharpener paysfor itself in five months 01/27/2025

Drill sharpener paysfor itself in five months Archway Engineering has invested in a drill sharpener from 1st Machine Tool Accessories, and the savings have been incredible. Danielle Toner, Production Manager at Archway, a site drilling equipment manufacturer, is overjoyed with the benefits the company has enjoyed from the new Darex XT-3000. A US-made Darex XT-3000 for repeatedly regrinding carbide and HSS drill bits to ‘as-new’ condition was delivered by sole UK sales agent 1st MTA to Archway Engineering’s Elland factory in July 2023. By November 2023, it had already paid for itself, as Mrs Toner had not purchased a single new carbide drill in all that time to replace broken or damaged bits. According to the work going through the factory, the saving was between £700 and £1,500 per month. Mrs Toner said: “We did not previously send drills out for resharpening, so worn bits were discarded. The cost was significant, especially for solid carbide drills. One component we regularly machine involves using a 160mm long, single-flute carbide drill, and we previously needed four of them to complete the part. If we ran out of bits, we couldn’t finish the job until the next drill delivery, which delayed assembly of our products.” “Now we simply resharpen a bit four times, and we are certain that the component will be finished on time. New carbide drills cost around £165 each, so the saving is considerable and contributes to lowering the cost of production.” This example is by no means exceptional. Another job requires three new carbide drills to make two parts. In a different process, an HSS taper-shank twist drill is put through 30mm thick EN19 high-tensile steel. A TC shoe made from an S355 hot-finish stainless steel tube is drilled in up to 16 places using a split-point, single-flute carbide drill that has to be repeatedly resharpened before the component comes off completely machined. Mrs Toner explained that some bits could be resharpened a dozen times or more, depending on their length, while maintaining top quality. It takes about one minute to sharpen the point, or a little longer if necessary to grind past a chip on a cutting edge. It happens quite often due to the toughness of the materials being machined and also because of a frequent need to drill cross holes at various angles into the wall of tubular components. This tends to damage the cutting edges of a drill as it breaks through. HSS jobber drills from the assembly department are also regularly sharpened, which Mrs Toner describes as ‘a massive saving’. It requires the 220-grit diamond wheel used for sharpening carbide drills to be exchanged for a 180-grit CBN grinding wheel. The process takes about five minutes, so batches of around 20 HSS bits are set aside and resharpened simultaneously. 1st MTA demonstrated the XT-3000 in the Elland factory before Archway Engineering purchased it with an attachment to process bits up to 30mm in diameter. Left and right-hand drills can be processed, and attachments are available for sharpening step drills, countersink and spot drills, and others with a 90-degree point. Standard sizes of carbide drills used regularly by the site drilling manufacturer are 8, 10, 12 and 14mm in diameter and up to 6XD in length. However, bits from 3 to 21mm in diameter can be accommodated in normal use. It resharpens bits in a three-step process. A drill is placed in a finger chuck, and the protrusion length is set at an alignment station. Carbide fingers enter the flute to fix the rotational orientation, and the drill is tightened in that position by rotating the chuck clockwise. The grinding motor is then started, and at a second station, the drill is sharpened on both sides while clamped in the same chuck. In an optional last operation, the chuck holding the sharpened drill is presented to a third station for point splitting to shorten the chisel line and lessen the force required for drilling components. In conclusion, Mrs Toner observed: “The savings that the Darex XT-3000 brings make it an obvious investment once you realise the benefits. We wish we had done it much earlier. The sharpener paid for itself in less than six months, after which the ongoing monthly savings continue to add to the profit margin on all jobs that require drilling operations, which is most of them.” “The sales arguments that 1st MTA make are difficult to ignore. We also purchase Chick workholding products from them, which have doubled productivity on one of our machining centres, and the supplier has also provided us with a new chuck for one of our lathes.” /episode/index/show/mtdmag/id/35025155

Precision tooling solutions for aerospace components 01/27/2025

Precision tooling solutions for aerospace components In the realm of cutting-edge aerospace applications, precision and performance are essential for transforming the toughest materials into high-flying components. Whether titanium alloys, nickel-based superalloys or advanced ceramics, these materials and the tools that machine them are the backbone of aerospace innovation. Kennametal’s tooling solutions are designed to tackle manufacturers’ challenges, helping them achieve higher precision, better surface finishes and increased productivity. Reliance on high-temperature resistant materials presents challenges. Traditional tooling doesn’t stand a chance when used in this environment due to friction, deformation and other component failure. For example, engine parts made from titanium and superalloys must endure temperatures over 1,000°F. That’s why high-temperature machining solutions become critical. It also means that the materials being used demand more than just tough tools; they must thrive under extreme conditions. High-Temperature Machining Goes the Distance Components powering everything from jet engines to exhaust systems are built to withstand extreme environments. Machining these components requires tools that can perform without compromising an aircraft’s structural integrity. This is exactly where Kennametal excels, delivering tooling solutions that meet aerospace’s toughest demands head-on. Innovative Tooling Solutions Kennametal’s high-temperature machining tools are specifically engineered to tackle challenges such as high cutting forces, heat buildup, and work hardening. They use advanced coatings, precision geometries, and heat-resistant materials for efficient machining under extreme conditions. Kennametal’s family of HARVI solid carbide end mills is a game-changer for machining tough aerospace materials like titanium and Inconel. HARVI™ Ultra 8X excels in airframe structural machining, while HARVI™ III is optimised for titanium applications. The HARVI I TE, with its twisted cutting edge, boosts corner stability and excels in ramping and helical interpolation. It features advanced anti-vibration and anti-friction technology. The innovative flute design with chip gashes reduces cutting forces, making chip evacuation super-efficient. Building on the success of the HARVI series, the newly launched HARVI II TE end mills feature a 5-flute design for aggressive cutting in ramping and plunging, as well as a proprietary W-flute shape for better chip evacuation and a stronger core. Overall, the HARVI tools deliver significant time and cost savings in aerospace operations, with impressive Metal Removal Rates (MMR) and tool life. Drilling composites like CFRP can effectively create fuselage, wing skins, and spoilers. Still, Kennametal’s KenTIP™ FS series of drills featuring a double-angle geometry is specifically designed for composites. Additionally, Kennametal offers KenShape™ MaPACS & MaxPACS and HiPACS countersink and drill solutions. These tools are engineered to handle the challenges of drilling composites, ensuring clean cuts and minimising issues like delamination and fibre breakout. By using these advanced tools, manufacturers can achieve high-quality results while maintaining the structural integrity of their components. When it comes to precision turning, especially with tough materials, Kennametal’s Beyond Evolution™ line of carbide and ceramic inserts will be effective. These inserts are built to handle the high temperatures associated with turning operations, which are common when working with hardened steels in landing gear and other components. Dealing with the hassle of frequent tool changes, especially when working on large components like wing sections, Kennametal’s KM™ and KM4X™ modular quick-change tooling systems come into play. They make tool changes super quickly without losing accuracy. For tasks that need high repeatability, like wing skin assembly, it’s crucial to calibrate tool holders to keep everything aligned perfectly regularly. “Aerospace manufacturers can achieve exceptional precision and productivity with our tooling solutions, ensuring every component meets our aerospace customers rigorous demands,” said Eva-Maria Weber, Manager Aerospace Business Unit CE. Overcoming Challenges in High Temp Machining In high-temp machining, precision, reliability, and speed are key and always at the forefront. Sometimes, problems arise, such as in thin-wall applications, surface finishes, and milling applications. Walking the Thin Line Thin-wall applications are often used to reduce weight without sacrificing structural integrity. Parts like fuselage skins, wing sections and other structural components rely on this technique. However, machining thin walls can be challenging due to vibration, deformation, and heat. To address these challenges, adjusting the feed rate and depth of cut can help reduce vibration before resorting to complex setups. Dampening tools at lower spindle speeds can improve stability without compromising finish quality. Kennametal’s high-feed mills and coated carbide inserts can successfully machine titanium for fuselage sections, maintaining wall stability and accuracy. In relation to spar fittings, machining composite components and aluminium, which consist of thin walls, requires careful part movement and precise and rigid fixturing while managing machining around multiple pockets. Milling Applications Machining materials like titanium, Inconel, and CFRP can present obstacles due to their strength, lightweight, and resistance to high temperatures. Superalloys and hardened metals generate significant cutting forces, leading to vibration, deflection, and tool wear, especially when tight tolerances are required. Aerospace components are often complex and have 3D shapes, requiring multi-axis milling and customised tooling strategies to ensure accuracy in hard-to-reach areas. “Our advanced milling solutions are specifically designed to address unique challenges, providing efficiency and accuracy when machining high-performance materials like titanium and Inconel,” said Patrick Mesnil, District Business Manager and aerospace business leader France & Benelux. Advanced tooling coated with Diamond-Like Carbon (DLC) or PCD can improve cutting efficiency. Optimised cutting conditions, including adjusting speeds, feeds, and depths of cut, help manage heat and forces during machining. Effective cooling solutions, like high-pressure coolant, dissipate heat and prevent workpiece deformation. Multi-axis CNC machines allow for precise machining of complex 3D shapes, ensuring accuracy in hard-to-reach areas. Surface Finish When it comes to high-temp machining, achieving quality surface finishes is essential. It can be affected by factors such as tool wear, cutting speed, feed rate and the material being machined. Advanced multilayer coating technologies like TiAlN and AlTiN on their carbide tools help control the heat at the cutting edge. These coatings act as a barrier, reducing friction and heat transfer. As new aircraft standards emerge, emphasising lighter, more heat-resistant, and sustainable components, continuous innovation in tool geometries and coatings plays a critical role in advancing component development. For example, larger components, such as engine cases, require challenging process controls and careful application with tool pressure in mind. Internal and external milling operations must also consider thin walls and fine surface finish requirements when working with tough materials. Additionally, turbine disks require managing low thermal conductivity and vibration to avoid part deformation. This requires application-specific tooling to provide the required cooling capabilities and productivity. As the industry continues to explore new materials and complex geometries, advanced tooling solutions must meet emerging challenges. In high-temperature machining, where precision, reliability and speed are crucial, Kennametal’s tools provide aerospace manufacturers with solutions to support the next generation of high-flying components. Designing and engineering tools that solve today’s challenges and anticipate tomorrow is essential. /episode/index/show/mtdmag/id/35025085

New development benchmarks in milling 01/27/2025

New development benchmarks in milling Milling originated in the late 18th century and quickly became one of the primary machining technologies. Nowadays, it is easier to imagine any machine shop with milling operations on the shop floor; it’s an essential process in manufacturing. The increasing demands of manufacturing drive this integral part of machining technology. However, there are specific aspects that uniquely impact the advancement of milling. We are witnessing significant changes in manufacturing that will have profound consequences on the development of milling directions. These changes are driven by various factors, such as the increasing accuracy of metal forming through precision investment cutting and precision forging, the widespread adoption of 3D printing, and the growing usage of new composite and sintered materials. Furthermore, there is a need to enhance productivity in machining hard-to-cut superalloys and titanium grades, and the strong focus on electric and hybrid cars in the automotive industry contributes to these changes. In addition, advancements in multi-axis machine tools have opened new possibilities for the precise machining of complex parts and enabled the implementation of new cutting strategies to improve productivity. In modern technological processes, there is a tendency to significantly reduce the machining stock intended for milling operations while simultaneously increasing the requirements for surface finish. Therefore, the advancement in milling is driven by the need for higher productivity, precision and sustainability in milling operations. Consequently, the main developments can be characterised as follows: Fast metal removal focuses on boosting the metal removal rate (MRR) to achieve higher productivity by significantly increasing cutting speed or feed per tooth. This is achieved through techniques such as high-speed milling (HSM) and, in rough operations, high-feed milling (HFM). Precision milling provides higher accuracy in milling operations. The utilisation of multi-axis machining centres characterises multi-axis milling to enable complex milling operations. Adaptive milling aims to develop intelligent systems that can adapt to changing conditions during machining. Sustainable milling strives to reduce the environmental impact of milling operations. It involves developing eco-friendly cutting fluids, recycling and reusing materials, and using energy-efficient machine tools and milling cutters. Success in these areas relies on the synergy of several key components: machine tools, cutting tools, and CAM systems. High-speed milling necessitates machine tool technologies capable of handling exceptionally high rotational velocities and advanced cutting materials and coatings for milling tools. Simultaneously, enhancing the precision of milling operations requires milling cutters with tighter tolerances and improved control systems and linear motor drives. In the case of multi-axis milling, the breakthrough lies in effectively controlled axes movement, along with the application of appropriate cutting geometries for milling tools. On the other hand, adaptive milling incorporates innovations such as using state-of-the-art monitoring systems, high-sensitive sensors, and efficient algorithms to optimise cutting data and tool paths in real-time. Moreover, sustainability advancements require energy-efficient milling strategies that employ suitable machine tools, cutting tools, and eco-friendly coolant techniques. Indexable milling reflects the advancements that feature exchangeable cutting inserts in machining operations. a) Advanced insert materials are an ongoing process to improve the cutting materials for indexable milling inserts, including the development of advanced carbide grades, ceramics, and ultra-hard cutting materials. b) Coating technologies with continuous R&D focus on new coatings to improve wear and heat resistance while enhancing lubricity. c) Progressive cutting geometry optimises cutting geometry and chip forming topology of inserts to improve cutting action and diminish cutting forces and chip flow in milling operations. d) Effective cutting material uses an intelligent insert design to provide maximum indexable cutting edges without reducing cutting capabilities. In addition, the distinct course on smart manufacturing requires the integration of digitisation into milling operations and tools. Regarding tools, digital twins and software applications have already become a ‘must’ feature of a comprehensive tool range. How can cutting tool producers rise to the challenge? Which milling tool solutions will provide the right answer to the emerging trends? Is the field of cutting tool manufacturing, often considered conservative in metalworking, capable of delivering a timely response to current demands? The recent advancements from ISCAR provide greater insights into these subjects. High-speed trochoidal milling involves following a curvilinear tool path to maintain a constant load on the cutting edge to eliminate spikes in load during material entry. This strategy is efficient for milling deep slots, pockets, and cavities. Additionally, trochoidal milling has shown excellent results when working with challenging materials such as high-temperature superalloys. The CHATTERFREE EC-E7/H7-CF is a new family of multi-flute endmills for trochoidal milling techniques. The family’s geometric design includes different helix angles and variable angular pitches to improve dynamic behaviour. These endmills are available in a range of length-to-diameter ratios (Fig. 1). Machine tools allow highly productive milling of aluminium alloys at extreme spindle speeds, reaching up to 33,000rpm. To meet this challenge, ISCAR has developed 90° indexable milling cutters that accommodate large inserts for a depths of cut up to 22mm (Fig. 2). The cutters have been designed to eliminate insert radial displacement, which may occur due to the high centrifugal forces generated during very high rotational speeds. High-feed milling (HFM) has become a widely adopted method for efficiently rough machining complex and flat surfaces. ISCAR offers a comprehensive range of HFM products to meet the demands of various industrial applications. Recently, the range has been expanded with new additions. The LOGIQ-4-FEED family of HFM tools, featuring specific bone-shaped inserts (Fig. 3), now includes tools with larger inserts. These new products significantly broaden the application range, particularly in the mould and die industry’s high-feed milling of large-sized cavities. Another addition is NEOFEED, a family of HFM tools with double-sided inserts, providing eight cutting edges for improved cost-effectiveness. Advancements in multi-axis machine tools and CAD/CAM systems have given rise to precise milling of complex shapes with minimal machining stock, using segment or barrel-shaped endmills. ISCAR’s program for these endmills encompasses three design concepts: a solid carbide design, an exchangeable MULTI-MASTER head, and a one-insert approach (Fig. 4). When milling high-temperature superalloys, cutting ceramics can substantially increase cutting speeds, reaching 1000m/min. ISCAR’s latest ceramic tools include ceramic solid endmills and indexable milling cutters with double-sided round ceramic inserts. The double-sided design aims to maximise the utilisation of ceramic material grades, such as ‘black’ ceramic, whisker-reinforced ceramic, and SiAlON (a silicon-nitride-based ceramic). These selected examples serve as good illustrations of the main directions of advancement in milling tools. As new demands arise, new solutions are required, and these new challenges will fuel the search for innovative tool designs. /episode/index/show/mtdmag/id/35025010

It’s the attitude that counts 01/27/2025

It’s the attitude that counts ARNO believes that machining is now something like Formula 1 racing: every little screw is tuned to increase performance. Thinking outside the box is essential, especially when considering cutting tools and turning. It would be helpful if users could always use the right combination of tools, inserts, and coolant supply. In Formula 1, everything is constantly scrutinised to glean maximum performance. Yet only the driver and the manufacturer who have mastered the overall package can reap the world championship crown. Despite all the optimisations and specifications, cutting tools for turning have yet to reach the end of their potential. Responsible tool manufacturers think about selling as many cutting tools as possible and include the tool holders and cooling supply into the equation. On the other hand, users should be open to tips, let consulting manufacturers approach them, and allow them to enter the production process. The potential that can be achieved in this way can provide a decisive leading edge. Be open to third-party expert tips For example, ARNO Werkzeuge has long been involved in the continued development of tool holders and coolant supply. Thanks to its customer proximity, the family-run company has a wealth of expertise from numerous applications and a wide range of holders with and without coolant supply. Users can rely on the best overall packages for small and large batches, as well as Swiss and fixed headstock lathes. “Here, too, we are not interested in maximising sales figures for high-margin products. We aim to find the best solution for our customers,” assures Sales Manager Dieter Wollensack from ARNO Werkzeuge. As an experienced technical advisor, he focuses on long-term and intensive customer relationships. He detests the promise of ‘double the service at half the price’ and pie in the sky. “I sometimes say to my customers: ‘No, that’s not possible’ or ‘We won’t do that’ and risk being turned down. I’ve always been successful with this approach - and ultimately, so have my customers.” Advice or not, process optimisation products must be convincing in practice. For this reason, the overall package consisting of a cutting insert or indexable insert with a matching tool holder and high-performance cooling must always deliver the best customer performance. This is exactly what users should attach importance to their tool partners to understand the processes and have the right overall package for every production situation. For example, universal packages for small batches, high-tech solutions for large batches, and special products for difficult-to-machine materials. Exorbitant promises never help. Innovative when it comes to ‘cost per part’ When tool manufacturers adopt this mindset, new products and solutions result. One example is the clamping holders with through-tool cooling for inserts that ARNO Werkzeuge developed in 2022. They are produced using a hybrid manufacturing process that combines additive technology with conventional CNC milling, achieving better surface quality. But why? Coolant flows directly where it’s needed. Three precisely aligned channels guide the coolant to the cutting edge from above and underneath without obstructing chip evacuation. The special geometry of the cooling channel creates a nozzle effect that greatly improves cooling compared to conventional channels. The outlet openings are always perfect—they need no adjustment. And since they are much closer to the cutting zone, the coolant significantly reduces the temperature. Experienced users will recognise the benefits immediately: greater process reliability, less vibration, better surface quality and a much longer tool life. Users have sent reports about tool life that is three times longer. Of course, this is not at all suitable for small batches - but when it comes to large batch orders, it’s just the right ace in the calculation where everything has to do with the cost per part. Hybrid holder: productive from additive The secret isn’t rocket science, but you must figure it out first. The shanks of the hybrid holders from ARNO Werkzeuge are produced using conventional CNC milling. On the other hand, the complex head part of the holder is attached directly to the shank using a 3D printing process. “This gives us new design freedom and outstanding stability,” says Werner Meditz, Head of Technology at ARNO Werkzeuge. The geometric design of the cooling ducts can be precisely optimised so that coolant is guided through the holder to the cutting tool at maximum efficiency and reaches the cutting edge directly from above and underneath. This cools the tool flanks in a way that was previously unthinkable. At the same time, the number of attachments required at the top of the head is reduced to the absolute minimum. The chip breaks as needed and is optimally evacuated - regardless of the cutting depth. “We get a lot more coolant to where it needs to go,” Meditz assures us. The innovative hybrid holder is exactly what clever users want - and this all comes from a tool partner thinking out of the box. Not only high-tech but also ‘basic work.’ But even when it’s not high-end, machine shops welcome innovative turning tool manufacturers with well-thought-out products. Meeting someone who can also offer the right holders and complete systems for small batches with frequent workpiece changes is refreshing. At ARNO Werkzeuge, you will find a wide range of turning holders for external machining, where the length is easily adjustable using a scale. “The ARNO special design is extremely simple and practical when it comes to adjusting the length and coolant access,” confirms Meditz. The holder and through-tool cooling are easy to install and ensure repeatable process reliability. Their nickel-plated, high-tensile, and precisely finished nature promises top quality and long tool life. The efficient cooling system, which feeds coolant directly to the cutting edge through three channels, not only ensures long tool life but also allows higher cutting speeds with optimised chip control. The machining time savings make the cost calculation look good. Variety of boring bars for internal machining Finally, we come to internal machining. Turning tool manufacturers have already given this much thought. First and foremost, the designers at ARNO Werkzeuge have also considered the customer’s situation and developed suitable boring bars for a wide range of applications. The range includes boring bars of steel and solid carbide, each with two possible coolant hole exits. Depending on the turning process, users can choose between a coolant channel from above (IKO) for through holes and a coolant channel from underneath (IKU) for blind holes. Accordingly, chips are guided forward away from the cutting edge (IKO) or behind the cutting edge and flushed out (IKU). This reduces wear. Boring bars come in right or left-hand versions with different shank diameters, a wide variety of clamping holders, and many approach angles. This variety alone shows that the manufacturer thinks from a user’s point of view. Combined with suitable mini indexable inserts from ARNO Werkzeuge, components from Dmin 4.8mm can be machined effortlessly, regardless of diameter and material. This is only the standard range, not customised products. This already promises long tool life because all ARNO boring bars are nickel-plated, high tensile and precisely machined, which certainly boosts confidence. Users looking for suitable, long-life productivity-enhancing tools for all their turning operations and processes should be glad that some manufacturers have adapted their thinking to include their customers applications. /episode/index/show/mtdmag/id/35024990

Ultrasonic deburring on manufacturers wavelength 01/27/2025

Ultrasonic deburring on manufacturers wavelength Intercable Tools GmbH has been firmly rooted in Bruneck in the Italian province of South Tyrol since it was founded in 1972. Since then, the family-owned company has been one of the leading manufacturers of connection technology and tools for professionals and the industry. Since May 2024, Intercable Tools has been using ultrasonic deburring technology from Swabian company ultraTEC Innovation GmbH to remove burrs from hydraulic units in a contact-free manner automatically. With Intercable Tec, a developer and manufacturer of automotive components, Intercable Tools forms a management-led family business with branches and over 600 employees worldwide. For some time, Intercable Tools had been looking for an automated solution to replace manually deburring hydraulic units of battery-powered hydraulic cutting tools made of aluminium and steel. Such hydraulic units are used in battery-powered perforators, which the company manufactures and distributes. These sheet metal punches are suitable for punching round, square and rectangular holes up to 3mm thick. The complex task for the ultraTEC was to remove all detachable burrs from the inside and outside of the components. “We were looking for an innovative alternative to manual deburring. It’s also important for us to produce our variants without set-up time,” said Heinz Pramstaller, Team Leader of Metal Production at Intercable Tools. “The deburring process should also be optimally integrated into the process, and the components should be cleaned using the same product carrier as the parts cleaning system.” The new ultraTEC A25 S system automates the manual process. The companies first contacted each other at the DeburringEXPO trade fair in Karlsruhe, Germany, in October 2023. Heinz Pramstaller brought the component to be deburred, so an initial deburring test was carried out on the trade show machine. The component was manually guided to the sonotrode, with a positive result. The advantages of this method over the previous manual deburring process quickly became apparent to Intercable Tools. Ultrasonic deburring means that the results remain the same, there is no damage to the drill holes, and uncontrolled material removal is generally avoided. It also guarantees that no holes are forgotten, which can happen with manual deburring. The ultrasonic deburring process has the advantage of cross bores being deburred and rinsed out simultaneously. The initial tests for Intercable Tools were, therefore, very promising. Non-contact ultrasonic deburring with the patented sonotrode forms the foundation of technology. Components to be deburred are guided in a water basin along the tip of an ultrasonic sonotrode, whose generated vibrations cause the burrs and chamfers to break off in an automated and energy-efficient manner. Stimulated by a generator, the sonotrode oscillates back and forth 20,000 times per second over 0.1mm. These generated vibrations move burrs and chamfers back and forth until they are broken off with sharp edges in a process-safe manner. Similarly, ultrasonic deburring does not apply temperature to sensitive components, which can lead to deformation and discolouration. In addition to deburring common metals, ultraTEC systems can be used with components made from various titanium and nickel alloys and fibre-reinforced plastics. From the deburring tests in Laupheim to commissioning in South Tyrol, numerous automated deburring tests were carried out with components from Intercable Tools at ultraTEC’s premises in Laupheim. Detailed documentation was provided for each test so that the specialists from Intercable Tools could assess each one accordingly. Regular coordination meetings and a visit from South Tyroleans in Laupheim led to them placing an order for the A25 S ultrasonic deburring system in late March 2024. Two months later, the A25 S was showcased for the first time as an innovation at the GrindingHub trade fair in Stuttgart, Germany, before preliminary acceptance was already carried out at ultraTEC in mid-June 2024. Four weeks later, the A25 S was operated at Intercable Tools in Bruneck in South Tyrol. “We’re delighted that we could implement the project quickly and that Intercable Tools chose ultraTEC to automate the deburring process,” says Thomas Benzing, Sales Manager at ultraTEC Innovation GmbH. “Maintaining a sense of partnership and trust when working with our customers is very important.” /episode/index/show/mtdmag/id/35024805

On a roll 01/27/2025

On a roll As a roll tooling and equipment design and manufacturing specialist, Bowers & Jones Ltd is increasing its in-house machining capacity and capabilities by investing in a new DN Solutions large-capacity, ram-type vertical turning lathe. The VTR 1216F machine from Mills CNC was acquired to fulfil a new steel mill order from a customer in the US that requires batches of high-precision straightening rings. Additionally, owing to the machine’s size, power, precision and versatility, the new investment will also help generate new business opportunities and growth in the US and other markets, consolidate its supply chain position with existing steel mill customers, and improve its UK precision subcontract machining operations. The new VTR 1216F machine is a large-capacity wide-column ram-type vertical turning lathe. It has been installed at the company’s 15,000sq/ft manufacturing facility in Bilston, near Wolverhampton, joining three previously acquired Mills machines supplied over the last four years. The existing machines are a Doosan Puma 5100B lathe installed in 2020, a Doosan DNM 750 II VMC with a 4th-axis unit installed in 2021, and a DN Solutions’ GT 3100L box guideway lathe delivered in 2023. Commenting on the relationship, Jane Sommerville, Bowers & Jones’ Managing Director, says: “We have built strong relationships with Mills CNC, and the breadth of the machine tool ranges they supply combined with the company’s first-class after-sales service and support means that Mills is invariably our first port of call.” Under new ownership since 2020, Bowers & Jones is committed to continuous improvement. It regularly monitors and benchmarks the performance of its manufacturing operations to identify and address current and future production inefficiencies and bottlenecks. The rollout of the company’s improvement programme, initiated four years ago when the change of ownership occurred, has been instrumental in streamlining and strengthening its in-house machining capacity and capabilities to deliver sustainable growth. Bowers & Jones supplies its roll tooling and equipment to steel and copper mills in the UK and worldwide. The company has recently made inroads into the US steel market. Through direct sales approaches aided by a third-party agent, it is expanding its presence in North America. Indeed, the company’s new VTR 1216F investment was primarily made to meet the needs of a new US customer whose rail ‘I’ beam sections, medium bar sections and angled bar sections are used extensively in the US rail and construction sectors. Jane Sommerville continues: “We needed a new large-capacity vertical lathe to machine large-diameter straightening rings for the customer. We won the business in Autumn 2023 and ordered the new VTR 1216F from Mills last October, expecting the machine to be delivered and installed in Spring 2024—just a few weeks before production of the rings was due to start.” However, in early 2024, the safety and security of transporting freight through the Suez Canal were unexpectedly delayed due to geopolitical issues. “We had to revert to Plan B quickly”, remembers Jane Sommerville. “The customer’s deadlines didn’t slip, so we had to use our existing machines to manufacture the first batch of rings – basically ‘holding the fort’ until the VTR 1216F eventually arrived.” The machine was delivered in early May 2024. To save time and minimise further disruption, it was delivered directly to Bowers & Jones’ facility from Felixstowe. Mills CNC performed its PDI, machine build, and installation on-site. Operator training followed soon after the machine was commissioned, and the VTR 1216F was cutting metal at the beginning of June. Commenting on the machine, Jane adds: “We had been looking at investing in a vertical turning lathe for some time – partly to take pressure off an older, large-capacity Berry & Binns horizontal lathe that we had acquired some years earlier, and partly to help spearhead new business growth in the US market. We approached Mills and two other suppliers to discuss our requirements and, looking at the proposed investment package as a whole, decided to place the order with Mills.” The FANUC controlled 50” chuck VTR 1216F machine boasts a maximum turning diameter of 1.6m and a maximum turning height of 950mm. It is equipped with a powerful 45kW 400rpm high-torque spindle, a servo-driven 12 tool ATC and an innovative quad tool holder with fast indexing that enables the use of four tools directly via the ram. The VTR 1216F delivers impressive processing speeds, improved machining flexibility, high accuracies and repeatability. Like all roll tool types, straightening rings are performance-critical components used in metal forming processes to enable the steel to pass through one or more pairs of rolls located on stands to reduce the material’s thickness, making it uniform and consistent. Where required, straightening rings give the ‘rolled’ material additional mechanical and application-specific properties needed for the ultimate end-user. The rings process the material into bar stock, rails and structural steel beams, angle and channel stock. These are used across many industries and sectors, such as construction, rail, energy, oil and gas and automotive. The harsh and demanding environments subject rolls to high wear, thermal stress and mechanical fatigue. Consequently, they need to be monitored regularly to maintain their dimensional and profile quality and consistency, with a need for replacements over time. The straightening rings machined on the VTR 1216F are made from D2, an alloy tool steel that is difficult to machine. They are machined from solid round bars in relatively small batches, with part cycle times being long and turning operations performed at low speeds. Roughing operations were undertaken on the company’s Berry & Binns lathe before the rings were sent for heat treatment. When the rings return, they are finish machined on the VTR 1216F to tight geometrical and dimensional tolerances with super-fine surface finishes. The heat treatment process gives the D2 rings their compressive strength, high wear resistance, toughness, and shock resistance properties—all crucially important for delivering high performance and long life in a demanding steel mill environment. Established in 1954, the company’s knowledge of metal-forming processes is second to none. The bottom line is that Bowers & Jones’ roll tooling solutions last longer and perform better than those of its competitors. Explains Jane Sommerville: “Our high-quality designed and machined rolls may cost a little more, but they are an investment and help customers save time and money by reducing re-profiling and replacement costs, limiting potential downtime and ensuring that customers’ mills keep rolling.” Bowers & Jones’ current five-year plan is ending, and the new five-year plan will be rolled out imminently. The company plans to upgrade its machine shop and further capitalise on new business opportunities in the US. The imminent change of administration in the United States, with its ‘Make America Great Again’ mantra, may well see the US steel market become stronger and more buoyant. /episode/index/show/mtdmag/id/35024785

Brother halves cycle times 01/27/2025

Brother halves cycle times In 2023, R&A Engineering won a contract to produce several hundred aluminium parts per month across six variants for assembly into sensors that optimise wind turbine orientation to maximise power output. The job involved tying up a pair of BT 40-taper VMCs, which impacted the Aylesbury-based subcontractor’s ability to do other work. So, the decision was taken to order and transfer production to a 30-taper, high-speed Brother M200X3 VMC with a 16,000rpm spindle. Delivered in August 2023 by Whitehouse Machine Tools, the Speedio M200X3 5-axis VMC has, on average, halved the time it takes to complete post-anodising milling, drilling and tapping operations on the six components. Therefore, the machine can perform the same work as the two VMCs used previously, which are now free to carry out other work. Ed Piotrowski, Operations Manager at R&A, said: “We approached a couple of 30-taper VMC suppliers, but Whitehouse was the obvious choice, even though we have never bought a machine from them before. It is a family-run firm like ours and has a similar ethos regarding service, which was obvious when we visited their showroom in Kenilworth for demonstrations.” “The Brother performs very well. Cycle times are now between one-and-a-half and four minutes, half of what they were before, and the ±0.05mm tolerance is held all day long without any problem. It is an accurate machine.” Established in 1985 by Ed’s parents, Richard and Alison, and currently employing 18 staff, R&A has grown by 50% since 2021. It has invested £800,000 in machine tools over the past couple of years and is looking to automate production in the turning and milling sections. The rationale is twofold: to take on extra work without compromising existing, long-running contracts; and to be more cost-competitive on the world stage to accelerate the flow of work already being reshored from Asia and elsewhere in increasing quantities. Ed has some interesting insights into why a subcontractor should invest in a 30-taper VMC. An adage in contract manufacturing is that one never knows what work will come through the door next. Therefore, the wider applicability of a 40-taper machine due to its size and power makes more sense. The first advantage of a nimble milling machine with a smaller diameter tool interface is high-speed production, which translates into greater profitability. Not only does the elevated spindle speed combined with up to 30m/min cutting feed rate provide generous metal removal rates, but idle times are lower due to 50m/min rapids in the X, Y, and Z axes. A less well-known benefit is the vastly lower power consumption of 30-taper machines. Ed advised that the M200X3 draws less than 10kVA, versus typically 50kVA for a 40-taper VMC or perhaps even more if it is an old machine. Energy bills are therefore lower and, as is the case at the Aylesbury facility, if a factory is close to its power supply limit, the lower kVA rating is a godsend. Reviewing the characteristics of the respective BT spindle machines, Ed observes that while power and rigidity are higher in a 40-taper VMC, modern, smaller-taper counterparts such as the Brother have a reasonably well-specified spindle motor with good torque, even in the medium to high-speed range. The drive motors are also consistent with robust machining, and face-and-taper-contact tool retention assists further, as in R&A’s case. “Although machining of light alloys is the province of this type of machine, using modern CAM software to create intelligent cycles involving light depths of cut and high-speed contouring means that tough and difficult-to-machine metals can also be tackled.” The M200X3 has a further advantage for OEMs and subcontractors alike. It is equipped with a torque motor to drive the rotary table, allowing a component to be indexed and rotated at up to 2,000rpm so it can be machined with a static turning tool in the spindle. Completing this second operation in-cycle without the need to re-fixture the part in a lathe raises accuracy and productivity. The mill-turn capacity in a small footprint holds much potential on the shop floor at R&A. Take, for example, the wind turbine sensor job for which the machine was purchased. All six parts undergo turn-milling on a lathe before being sent out for anodising. The Brother must only remove the insulative anodic layer in certain areas to provide electrical conductivity. With the latter machine’s turning capability, all parts could be completely machined. Richard and Ed are actively considering this possibility, which would require automated component handling to be retrofitted. In addition to seizing opportunities in the renewable energy sector, R&A is also taking advantage of growth in vehicle electrification. Two aluminium parts have already been produced on the Brother VMC for the latter sector. One is an EV engine terminal block, which is milled, drilled and tapped in a 20-minute cycle. Another engine part has been transferred to the M200X3 from a 40-taper machine, with the part now machined in eight minutes rather than 12, again leading to more competitiveness, shorter lead times and more overall capacity on the shop floor. Ed is already planning the next job for the Brother. Water purification work accounts for about one-third of the subcontractor’s turnover. One of the parts machined from Ertacetal, an electrically conductive plastic, is currently turned and milled in four set-ups on three other machine tools. On the Brother it will come off complete after two set-ups. /episode/index/show/mtdmag/id/35024770

Can the aerospace supply chain keep pace with demand? 01/27/2025

Can the aerospace supply chain keep pace with demand? The aerospace industry is experiencing unprecedented growth, driven by record demand for commercial jets, defence programmes and space exploration. To seize this opportunity, suppliers must find ways to ramp up output without compromising quality, innovation, or cost. By Will Stirling The biggest hurdle facing the aerospace industry is how to scale up production. Airlines are investing heavily in new fleets, governments are increasing spending on advanced defence systems, and private companies are pushing the frontiers of space exploration and satellite technology. While this growth is a welcome rebound after years of turbulence, it has exposed bottlenecks in the supply chain, exacerbated by rising operational costs, material shortages and evolving regulatory requirements. Nowhere is this challenge clearer than in the commercial aircraft backlog, which has ballooned to nearly 16,000 planes – valued at more than £250bn for the UK alone. At current production rates, clearing this backlog could take over a decade. Meanwhile, demand continues to climb as airlines place hundreds of new orders yearly. Yet, this pressure brings opportunity. “The fact I can’t name another industry with a 10-year-plus backlog worth over US$1.5 trillion globally shows just how massive the growth trend is,” says Balaji Srimoolanathan, Director for Aerospace, Space and the Aerospace Growth Partnership at ADS. “The primes and top tiers are diversifying their suppliers, sustainability is becoming ever-more critical, and new technologies are accessible and affordable. There is more business to be won by a greater number of suppliers than ever before, adding up to more opportunities, particularly for those with the right tools and technologies in place.” Srimoolanathan explains that the key to unlocking these opportunities lies in integrating advanced capabilities, such as intelligent manufacturing systems, into today’s production processes. This move has been proven to drive greater efficiency and agility without comprising stringent quality standards. Digital Innovation in Action As production ramps up, shortages of critical components like semiconductors, electronics and raw materials like aluminium and titanium continue to cause delays. The pandemic’s ripple effects are still being felt, slowing assembly lines and affecting deliveries. Even seemingly minor components, such as fasteners, are in short supply. Recognising this, LISI Aerospace partnered with the University of Sheffield Advanced Manufacturing Research Centre (AMRC) to explore how digital tools can drive process improvements. Together, they developed a cutting-edge smart production line at LISI’s Rugby facility. The pilot line integrates five connected factory machines, each handling a distinct process. Key innovations include sensor data and data analytics to predict component quality, alongside an expanded apprenticeship programme to support new roles like software developers and data analysts. The result is a more than 100% performance improvement, enabling the Rugby site to hit record turnover and win additional contracts worth over £2m. The project also spurred a dedicated process development department, created a dozen new jobs and paved the way for a further £6.5m investment to implement two more connected production lines by 2027. An AMRC spokesperson said the project demonstrates how industrial digital technologies can transform operations. The success has ‘set a new benchmark for fastener production processes’ and clearly shows the potential of technology-driven innovation in aerospace. Process Improvements Within Constraints While LISI’s collaboration showcases the benefits of innovation, industry-wide progress is often hampered by a reliance on established processes and materials. “The industry is built on aircraft and parts certified to specific production techniques, many of which were designed decades ago,” explains Andrew Mair, Chief Executive of the Midlands Aerospace Alliance (MAA). While this reliance on legacy methods may limit flexibility in core manufacturing processes, there’s significant scope for improvements in areas that run parallel to assembly. Upgrading to integrated software platforms for production planning, resource management and inventory tracking, for example, is an area where many smaller manufacturers lag, yet can unlock substantial efficiency gains. Similarly, using robotics and automation to move materials or load machines can streamline operations and reduce manual labour and downtime. Design innovations also hold promise. Advances in simulation and digital twin technologies allow suppliers to optimise components and assemblies before physical production, compressing design cycles and identifying potential issues earlier. Generative design, where AI-driven software explores thousands of potential configurations, is helping create lighter, stronger, more cost-efficient components. Combined with additive manufacturing, suppliers can prototype and produce highly complex parts faster and, importantly, with significantly less waste than traditional ‘subtractive’ machining. For instance, Airbus and Autodesk have used generative design and additive manufacturing to produce the world’s largest 3D-printed cabin component. Inspired by cellular structures and bone growth, the latticed partition to separate the passenger cabin from the galley is structurally as strong as conventional designs but 45% (30kg) lighter. When scaled to the entire cabin, Airbus estimates that the new design approach could save up to 465,000 metric tonnes of CO2 emissions a year. Government Backing Fuels Further Investment Recognising the transformative potential of advanced technologies, recent government announcements are geared towards accelerating adoption. One such initiative is the expansion of Made Smarter, an industry-government programme aimed at helping SME manufacturers adopt technology and build digital skills. Since its 2019 launch in the North West, Made Smarter has engaged with 2,500 manufacturers, funded over 330 technology projects, created more than 1,500 jobs and upskilled nearly 2,800 workers. Its upcoming national rollout to all nine English regions by 2025/26, followed by Scotland, Wales, and Northern Ireland in 2026/27, will extend those benefits to thousands of manufacturers across the UK. “The programme has proven the value technology and digital skills can bring,” says Donna Edwards, Director of Made Smarter NW, who described the national roll-out as “a huge vote of confidence in the contribution SMEs make to UK manufacturing.” Additionally, the government’s announcement of £975m to extend the Aerospace Technology Institute (ATI) programme to 2030 was welcomed – although many favoured a longer-term commitment. With matching industry contributions, the funding will exceed £2bn, providing critical support for ultra-efficient and zero-carbon technologies. “This support for R&D is crucial at a time the sector is ramping up rates to meet today’s demand while delivering ambitious technology programmes to bring next-generation aircraft technologies to reality,” says Gary Elliott, CEO of ATI. Plotting a Sustainable Flight Path The UK is making significant strides in sustainable aviation. The latest development saw a new Sustainable Aviation Fuel (SAF) mandate come into force on New Year’s Day. The mandate requires that 2% of UK jet fuel demand be met by SAF, rising to 10% by 2030 and 22% by 2040—delivering up to 6.3 megatons of carbon savings annually. The mandate will be bolstered by the introduction of a revenue certainty mechanism to de-risk investments in new SAF plants and provide the confidence needed to scale domestic production. The potential of hydrogen-powered aviation is also gaining momentum, with Russ Dunn, GKN Aerospace CTO, recently named as the new chair of the Hydrogen in Aviation Alliance. The HIA’s first major report, published in 2024, outlined a clear roadmap for industry and government to drive adoption. Yet, realising this vision requires more robust support for R&D, particularly within the manufacturing supply chain. Andrew Mair explains that nearly all the R&D support currently goes to large corporations or start-ups, leaving the existing supply chain underserved. “We need more regionalised support, particularly for clusters like the Midlands Aerospace Alliance, to ensure small companies get the backing they need.” Srimoolanathan of ADS underscores that aerospace is uniquely positioned to deliver immediate and long-term benefits for the UK economy. “The backlog presents an opportunity for short-term growth, job creation and technological advancement,” he says. “But this hinges on balancing the immediate demands of today with strategic investments in areas like zero-emission technologies. With sustained support, the UK can maintain its position as a global aerospace leader while delivering tangible economic and environmental benefits.” /episode/index/show/mtdmag/id/35024680

Stand and deliver: New industrial strategy must put the fizz back in UK manufacturing. 11/20/2024

Stand and deliver: New industrial strategy must put the fizz back in UK manufacturing. 2024 was a mixed year, with some stellar announcements like Tata Group’s gigafactory investment offset by the cancellation of Phase 2 of HS2 and a budget black hole to pay for, but an Industrial Strategy may give the industry the long-term stability it needs. This article is by Will Stirling The Chancellor Rachel Reeves received a boost a week before her Autumn Budget when the IMF revised its forecast for UK growth this year to 1.1% (up from 0.7% in July) and 1.5% in 2025 – the biggest upward revision for any advanced country. It’s a sign of better things to come, and 2024 was not a banner year in manufacturing, more one defined by steady stability, yet it still notched up a few memorable headlines for British industry. Spiralling costs meant the previous Tory government cancelled Phase 2 of HS2 from Birmingham to Manchester, affecting hundreds of supply chain companies, which the new Labour government partly blamed for the cost overruns. The Secretary of State for Transport Louise Haigh launched an independent review to ensure lessons will be learned and the costs for HS2 are controlled. The cost of Phase 1, London to Birmingham, is expected to reach £66bn. Covid and the semiconductor-shortage-affected UK automotive sector got a fillip in February when Agratas, the battery division of Tata Group, confirmed a new £4bn battery gigafactory in Somerset. It was a relief for the car sector to see the UK stall on the global league table for gigafactory capacity, a key metric for car plant investment. While carmaking recovered strongly in 2023 after semiconductor supply returned, it is slowing down. By August, the UK had manufactured 522,833 cars, down 8.5% on production at the same point in 2023 when ythe figure was 571,671. Interestingly, year-to-date vehicles for the domestic UK market had increased by 12%, but exports, representing over 84% of all car production, were down 13.6%. The production of electric cars, including hybrids (EVs), fell by 26%. Automotive business group SMMT said this decline is expected to be reversed in the longer term as new models come on stream. Massive manufacturer discounting saved car sales in Europe in September, pushing BEV sales to 56,387 registrations. Siemens opened its new train factory in Goole, Humberside, in October and announced a further £40m in addition to the £200 investment in the Goole Rail Village, which will now bring up to 1,000 new jobs to the region, as well as around 1,700 supply chain job opportunities. In addition to maintaining the bogies from Siemens’ 572 trains running in the UK, it will also include new production lines for assembling bogies for new trains, which will be the first for Siemens in the UK. Aerospace is battling delivery rate challenges: after Covid, orders poured in, and the industry is pulling on all levers to find ways to go above ‘Rate 60’ into the consistent 80s or even 90 aircraft per month to reduce long delivery times. Ninety commercial aircraft were delivered in August, the highest in that month of the year since 2018. But that’s not the whole story. While the global backlog of aircraft on order is 15,651 planes according to the industry group ADS - an extraordinary number - aircraft orders in the year-to-date are two-thirds behind 2023 levels. Perhaps it was a sign that Brexit was the past. The FA appointed Thomas Tuchel as the senior men’s coach, causing gossip as the first German coach of the England football team. A week later, Britain and Germany signed a government-described “landmark’ defence agreement to boost security, investment, and jobs. German defence giant Rheinmetall will build a new factory in the UK to make barrels for artillery guns, and German marine surveillance aircraft will supply patrols from RAF Lossiemouth. The factory will need British steel and will create 400 jobs. It's the first defence pact with Germany of this scale, although both countries already collaborate on making armoured vehicles, for example. In October, BAE Systems Maritime launched the sixth Astute class submarine, Agamemnon. Attention will soon switch to the multi-billion AUKUS submarine (SSN-A) programme, where the boats will be built in the UK and Australia. Fhaheen Khan, senior economist at Make UK says “Manufacturers this year experienced the most stable period of business conditions in almost a decade, despite still facing higher costs, tight interest rates and skills shortages.” While it could be seen as a year of two halves – the first six months boasting strong production, order books and investment intentions, and the second looking far more mixed due to an inevitable domestic market slowdown –manufacturers remain buoyant in their expectations.” h Accountants and business advisors are expecting more investment in the economy in 2025, following several years where major events and inflation have made business conditions that could be generally described as ‘sh*t’. Fhaheen Khan thinks the new 10-year industrial strategy is an important milestone in achieving economic growth, although some seasoned business leaders will say they have heard it all before. It’s hard to remember, but the UK has had at least four official industrial strategies since the 2008/9 recession: in 2009 (Mandelson), 2012 (Vince Cable), 2017 (Greg Clark) and now in 2024. Khan says “It's highly encouraging that advanced manufacturing will be a key sector driving that growth, and the Industrial Strategy Council will help lay the pipework needed to modernise UK industry through the wide adoption of AI, computing, and techniques like 3D printing.” Of particular relevance to MTD readers, the numbers show that industries specialising in producing capital equipment like machinery, electronics and metal fabricators have experienced a positive year. This is due to strong exports to the US and the EU as many Western countries are investing in the kit to modernise their manufacturing – for example, the US’s Inflation Reduction Act and, one could say, on the wave of ‘Make America Great Again’. Khan says “These subsectors have much to look forward to in 2025 as economic conditions stabilise further, inflation cools, and interest rates are loosened." The manufacturing technology expo MACH 2024 organisers said visitors were up 6% on the previous show and reported a good vibe. Greg Capp, sales director at EDM machinery firm Sodi-Tech, said: “Footfall has been the best in a long time. On Day One, we had enough enquiries for the next six months.” Overall, investment in manufacturing in 2023 (last full year) is up by 4% on 2022, from £40.24bn to £41.8m, and economists expect this to rise in 2024. Despite the numbers and late positivity, on the ground, some manufacturing machinery vendors and subcontractors report a frustrating year where the anticipated rush of orders failed to materialise. That flat confidence from 2022-2023 seemed to be overspilled into the year’s first half. Andrea Wilson at deep hole drilling and boring engineering company Hone-All Precision says “2024 has been a challenging and varied year for most businesses. “Uncertainty and political instability have created conditions that have not been beneficial to business and have created barriers to growth. “The creation of the 10-year Industrial Strategy will hopefully give business and investors the confidence they have been lacking the last few years.” The new industrial strategy focuses on eight sectors: advanced manufacturing, clean energy industries, creative industries, defence, digital and technologies, financial services, life sciences, and professional and business services. High-tech, hard-tech, high-potential companies can benefit hugely from close government support. The top two sectors in the strategy are advanced manufacturing and clean energy industries. “Tokamak Energy does both!” says David Kingham, the executive vice chairman and a co-founder. He says that the company that designs, manufactures and operates a plant for nuclear fusion to generate power aims to accelerate the development of fusion energy, the most valuable technology of the 21st Century. “We were delighted to see the new consultation on the Industrial Strategy. A company like Tokamak Energy, with over 250 employees and global ambitions, can grow rapidly if we have consistent strong backing from the government.” The company has had spectacular success in recent years with the record-breaking ST40 high field compact spherical tokamak – which reached 100 million degrees Celsius plasma ion temperature, the threshold needed for commercial fusion energy. Its high-temperature superconducting (HTS) magnet development has also set records for magnetic field strength at a temperature of 20,000C. David says: “Our industrial strategy is to pursue fusion energy by assembling consortia around our core technologies to provide the complimentary capabilities necessary for the development and deployment of fusion. This will require major investment by governments and consortium partners, but the prize is the elusive goal of commercial fusion energy. The fastest achievable timeline for fusion is 10 years to a 50MW pilot plant, a goal set by the US Department of Energy milestone-driven fusion development program. “So a bold, consistent industrial strategy from the Government could enable the UK to have its fusion “cake” in the long term and “eat” the economic benefits of the magnet spin-off technology in the short to medium term.” In the supply chain, companies like Hone-All Precision want long-term stability, vision, and potential targeted support through programmes unafraid of ‘picking winners’ that have previously blighted attempts to assist the industry within state aid rules. Managing Director Andrea Wilson says “The new Labour government must commit to long term strategic thinking and investment decisions, and the newly formed Industrial Council will hopefully achieve this.” “The council’s success will be increased dramatically if it's informed by business leaders, owners, and most importantly, if it includes SME representation. The outcome of these two positive moves will hopefully result in us seeing the confidence and stability we all need to thrive.” Machine tool and machinery suppliers need orders, and for that, their customers need confidence to buy. Adrian Haller, managing director of Bruderer UK, a leading manufacturer of precision high-speed presses says “The UK has a fantastic opportunity in advanced engineering, and we have so many brilliant companies – at all levels of the supply chain – that are prospering despite the lack of a coherent Government strategy to support the sector.” “This isn’t tubthumping; this is what we see every day when our sales engineers and installers commission precision high-speed Bruderer presses on shop floors across the country. Imagine what we could do if we had a long-term Industrial Strategy that focuses on our strengths and invests in them? And I don’t mean the odd grant here and there. It needs to be substantial and flow down to SMEs – that is the critical bit. For industry to become more efficient, an area to improve is the education of manufacturing engineers about new, ‘smart’ technology. Mark Weymouth, MD of PLUS Automation and UK representative for Contrinex and Satron, who runs a popular LinkedIn newsletter says “There's a pervading tendency for engineers to buy and commission what they know and not look at new, better plant and equipment that can raise productivity.” While PLUS Automation is in its fourth year of growth, many food and liquid process manufacturers are not explaining this technology to their site engineers. He says “The UK is about seven years behind mainland Europe in adopting many process technologies.” Although the increase in employers’ national insurance payments may dampen this optimism, the indicators are that this new strategy for industry will help businesses, especially those in advanced manufacturing areas. /episode/index/show/mtdmag/id/34032234

Spark of Innovation. 11/20/2024

Spark of Innovation. Anotronic Ltd is a well-recognised subcontract machining business and manufacturer of high-quality EDM fast-hole drilling and EDM die-sinking machine tools. Founded in 1982, the Leighton Buzzard business started in ECM, ECD and EDM tooling and machining, evolving to the production and growth of its own ECM and ECD technology brand. Along this journey, the company has worked with Sodi-Tech UK and the Sodick brand of machines. Martin White, Managing Director of Anotronic Ltd, says: “My father started the business in 1982, and I joined the company in 1985. We tend to machine a lot of difficult materials such as inconel, titanium, special stainless steel, and everything that is difficult to machine. We take on the worst jobs because we can - and we have all the machines and processes in-house to do what we need.” Over the years, Anotronic has continually expanded its factory footprint, services and range of machines. This has resulted from an aggressive growth strategy, staff development, and investment in the latest machine tool technology. The Bedfordshire manufacturer currently operates three Sodick machines, with the latest ALC600G Premium wire EDM with linear motor drive technology arriving recently. The high-end plant list gives Anotronic the edge over its rivals. The Sodick ALC600G Premium from Sodi-Tech UK, with its spacious X, Y and Z-axis of 600 by 400 by 500mm and the U and V-axis travel of 120 by 120mm, clearly gives the company an edge. Martin recalls how Anotronic arrived at the ALC600G: “We always buy premium machines, and as the company has become more experienced, we always look to buy better machines. This always comes down to reliability and the ability to run unmanned. We have a Sodick AQ35L die sink machine that we’ve had for a very long time, and Sodi-Tech UK has looked after this machine for us for over 20 years.” The reliability and performance of the Sodick AQ35L meant that when Anotronic was in the market for another EDM machine, it once again turned to the Sodick brand. Martin says: “We bought a Sodick AG 600LH around seven years ago. That machine enables us to do tool work up to 500mm high, which we regularly do. We have a large bobbin on this machine, enabling us to run 70 to 80 hours unmanned.” The remarkably high level of lights-out machining with the Sodick AG600LH and its incredible reliability persuaded Anotronic to invest in its latest EDM machine, the Sodick ALC600G Premium with linear motor drive technology. “We bought this latest machine because we had a project with a sister part. The project typically consists of 40 parts that would maybe take us three months to complete. We suddenly had an order placed on us last year for 300 parts. We couldn’t have done this without another machine, as we knew we would have had to have been machining 24 hours a day to get the parts done.” Sodi-Tech UK Sales Manager Richard Bailey says: “Martin and Anotronic don’t just take on run-of-the-mill CNC jobs. This company tackles the higher end of the industry and often the parts that companies don’t want to tackle themselves. Anotronic looks at jobs from an application perspective rather than a ‘machining time’ point of view. With the Sodick technology and the special characteristics within the machine, Anotronic can utilise this to run all of its applications and do jobs that are unique and out of the norm. In this instance, the application that Martin has been working on requires some very steep angles. The ALC600G Premium has very large U and V-axis travel, allowing the processing of tapered angles up to 45°. So, when it comes to machining this part, it can be done in situ with the integration of a fourth and fifth axis.” “Manufacturers can also use the on-board technology and IQ software system that brings Anotronic’s model into the machine and draws the profile on-board utilising the U and V-axis cutting technology. The programme is generated, the parts machined, and the job is complete!” “We're using a very complex 4-axis programme to cut a rotary part with 45° slots in it. The only way we could do that was to use the software we currently use and without it, we couldn’t manage to do the part. So, we used the on-board software within the CNC control of the Sodick machine to create a 3D model and a tool path to cut the part. This is machining at extreme angles. We're cutting at 45° and machining up to 40 to 50mm in the U and V-axis to create this particular part. We also had to specify wide nozzles and wider guides to machine this part, and the ALC600G did a brilliant job.” “I have been a Sodick user for 35 to 40 years, and the beauty of the Sodick machines is that you can jump straight into a point anywhere in the programme without editing the entire programme. It makes things very easy as it is a powerful and user-friendly software system. It has many benefits, such as the negative offsets - normally, you have to cut a comp on a machine, but with the Sodick, we can drive the comp the other way and cut the other side of the part using a negative value. Most control systems would just throw that out, whereas the Sodick accepts it and gets the job done.” “I was working 15 to 20 hours daily, which was too much. I wasn’t seeing my kids growing up, and something had to change, so we went down the automation route. We have a great team that works very hard and helps us reach our common goal - we run a lot of machines with very few people through our application of automation. Sodick is a very established brand, and they have a great customer base and exceptional knowledge with engineers who are really, really good. I've known Peter at Sodi-Tech for over 35 years, and this relationship is based on our excellent support - it’s been a fantastic marriage between the two companies.” /episode/index/show/mtdmag/id/34032226

Six of the best 11/20/2024

Six of the best With 75% of its turning centres bought from Dugard Machine Tools, it's safe to say that C&K Precision Engineers Ltd is reaping the rewards of working with the South Coast machine tool specialist. The Stoke-on-Trent manufacturer is a subcontract machining, assembly and fabrication business serving the medical, aerospace, surveillance and general manufacturing sectors. Working in these high-end segments, C&K Precision demands machine tools capable of delivering high-quality, tight-tolerance workpieces from the most challenging material grades. Matthew Kelsall from C&K Precision Engineers says: “We moved to a new large facility in 2017, and since then, we have continually grown. We’ve invested in new machines with a better working environment and aim always to increase productivity. There is a skills shortage, and we are lucky to have a good team around us, but we have to maximise that with the most productive machines.” This is why six of the company’s eight turning centres have been purchased from Dugard Machine Tools. The second-generation business was founded in 1969 kand eeps returning to Dugard, Matthew says: “One of the main things is reliability. The first Dugard machine we bought has been with us for six years and has been remarkably reliable. It’s a very robust and rigid machine with box guideways, and we need that as we machine many exotic materials - we have a lot of faith in the machine.” The turning centres supplied by Dugard are all fitted with a Siemens CNC system. “With a lot of machine tool manufacturers, if you want a machine built to order, it typically takes twelve months to wait, and we simply couldn't wait for that. Dugard had a machine in stock with many additional bells and whistles, such as a sub-spindle, that we never had before. The success of that machine led us to buy two more machines. That’s because if something serves you well, you stick with what you know.” “Since we purchased the first machine, we found that we could get more and more work through it, which eventually created a bottleneck. We had to do something about the bottleneck, so we bought a second machine with a Y-axis last year. We have now just had the third machine installed”. As a turner operating four machines at C&K Precision Engineers, Matthew Gerrard says: “The machines are built extremely well, and they perform brilliantly on materials like inconel 625 and titanium – they fly through the material. You can make massive cuts on the Dugard SMEC machines, whereas others can stall. This is due to the really high quality and high specification motors and the box way construction. We also love Siemens control as it is very user-friendly and has a lot of technical add-ons. If we're doing jobs out of titanium that may have just a 0.9mm wall thickness, the Dugard SMEC machines ensure that you don’t get any vibration. Additionally, the machines have BMT65 toolholders that are very large and robust for heavy-duty cutting.” “Looking at the first machine we bought with the Y-axis, it’s just so much more versatile and capable than our other machines. We have other machines with live tooling, but the Dugard Y-axis is perfect for opening slots and counter-boring holes. We were so impressed by the sub-spindle on the SMEC SL2500SY that we purchased a SMEC SL2500Y, which is an almost identical machine except for the sub-spindle. We purchased this as we only needed one machine with the sub-spindle, but we still needed a machine with a Y-axis for doing one-off jobs.” “We've just added a SMEC SL2000, and my son, who is just starting his apprenticeship, is on that machine. It doesn’t have the live tooling facility, but it has a Siemens 828 CNC control and is perfect for learning.” Matthew Kelsall says: “When you buy a machine, nobody wants to be stuck at the end of a phone talking to someone you’ve never spoken to before, but when you speak to Dugard, you have a great relationship that work well.” /episode/index/show/mtdmag/id/34032218

Quick holemaking 11/20/2024

Quick holemaking The design concept of assembled drills with exchangeable solid carbide cutting heads, adopted by ISCAR at the turn of the century, significantly altered the company’s holemaking product program. As part of this concept, a precise carbide head is mounted in a steel holder using the ‘self-clamping’ principle, which relies on the holder’s elastic deformation without any mechanical clamping means. This approach is characteristic of various successful ISCAR products, such as the SELF-GRIP and MULTI-MASTER tool lines. These have substantially improved machining performance and revolutionised traditional perspectives on cutting tool design. This is complemented with stoppers and locking sections for reliable security. In the assembled drills with carbide heads, the cutting head has a specially shaped rake surface to optimise chip formation and a centring area to ensure high accuracy. The drill body is produced from a high-strength steel grade and features the innovative design of the head pocket, helical flutes, and internal channels for coolant supply. Advancements in technology, particularly in powder metallurgy processes and CNC machining, have made this design feasible. The concept of assembled drills with carbide heads guarantees several key advantages: 1. With a rigid structure, reliable clamping principle, unique cutting geometry and advanced carbide grade of the heads, the drills guarantee productive results. This significantly reduces cycle times and enables high-quality holes. These drills can be used for machining a wide range of materials, including steel, stainless steel, cast iron, titanium and high-temperature alloys. 2. High repeatability and ISCAR’s ‘no-setup-time’ principle promise that a worn head can be replaced without removing the drill from a machine, eliminating additional setup operations and considerably decreasing downtime. The simple change of the heads makes the drills user-friendly and easy to handle. 3. The drills are available in a wide range of diameters and overall lengths to suit various applications. 4. The use of interchangeable heads diminishes the need for a large drill inventory. ISCAR’s drills with exchangeable carbide heads provide customers with a valuable tool solution to enhance the profitability of holemaking operations. Over the past 20 years, these drills have undergone significant changes. Beginning with the CHAMDRILL family, each new phase in the concept’s enhancement has led to new products that outperform their predecessors. Today, SUMOCHAM is ISCAR’s most popular family of assembled drills with exchangeable carbide heads and is highly regarded by customers. The continuous search to increase drilling productivity, mainly when machining materials that produce fine chips, has created the LOGIQ-3-CHAM – a family of three-flute drills that utilise the same self-clamping approach. ISCAR’s development of carbide-headed drills continues to aspire. Unsurprisingly, ISCAR’s latest product campaign, LOGIQUICK, has unveiled innovative designs that enrich the existing product families, broaden their scope, and pave the way for new application areas. The new holder with three flute heads allows a 10:1 drilling depth-to-diameter ratio. The holder’s main feature is a specific flute design that minimally affects the tool’s structural strength. Another innovation is the expansion of the LOGIQ-3-CHAM family application to include counterboring. The specially designed three-flute heads are mounted on existing tools and transformed into highly efficient counterbores. The unique design features of the heads include a corner chamfer for rapid chipping, specialised deflectors for improved chip formation and a unique margin for enhanced support and guidance. This significantly boosts performance when machining materials like sticky steel, stainless steel and high-temperature superalloys. This design facilitates a broad spectrum of counterboring operations, ensuring high-quality holes, even when machining cross-holes with inclined surfaces. The CHAM-SPADE-IQ is a new family of holemaking tools with exchangeable heads. Introduced as part of the LOGIQUICK, the family provides a solution for drilling steel profile construction beams. Machining beams often occurs under non-rigid conditions, presenting a significant challenge for manufacturers. To address this issue, drilling tools must have an adaptive cutting geometry to compensate for the lack of rigidity. The newly introduced family, dedicated explicitly to profile construction, includes two flute carbide drilling heads and reinforced steel holders. The heads feature a specific self-centring cutting edge for secure hole penetration and sharp corners to prevent deformation. The holders’ durable structure maximises the tools’ dynamic stability when drilling at a depth-to-diameter ratio of up to 5. New drills with MULTI-MASTER adaptations that carry exchangeable carbide heads essentially serve as a ‘bridge’, connecting the successful SUMOCHAM and MULTI-MASTER families. The drills are a component of a versatile modular tool assembly that allows the mounting of drilling heads on a wide range of MULTI-MASTER tools. This facilitates an easy and quick change of the heads and the drill bodies. Moreover, the modular concept provides straightforward customisation and flexibility regarding overall length and diameter and finding the optimal tool configuration. It’s worth noting that the holemaking innovations in the LOGIQUICK campaign aren't solely represented by assembled tools with exchangeable heads. Several products of another design concept can also be highlighted. The three-flute flat-bottom solid carbide drill with internal coolant channels is one such product. The drill features a small isle for improved penetration, wavy cutting edges for assured chip control, an optimised core diameter to increase tool rigidity, and narrow wiper sections to reduce friction. This improves surface finish and combines with an internal coolant supply that extends tool life and improves chip evacuation. These incredible attributes contribute to the promising prospects of this product line. In the boring line, a new series of boring heads with extra fine digital adjustment has replaced the existing heads with an MB connection. In the milling line, the portfolio has been enhanced with the addition of the The QUICK-D-MILL is a family of multi-functional indexable cutters. These versatile ‘all-in-one’ cutters are suitable for various machining applications, embracing the milling of shoulders, slots, and pockets and drilling flat-bottom holes. The overview of the mentioned products highlights that ISCAR’s focus on holemaking continues to drive its development efforts. With the metalworking industry seeking solutions to enhance holemaking performance, ISCAR is confident that its latest LOGIQUICK drilling developments will effectively meet the industry’s demands. /episode/index/show/mtdmag/id/34032198

Prima Additive and Comau respond to Euro 7 standards. 11/20/2024

Prima Additive and Comau respond to Euro 7 standards. Prima Additive and Comau, two Italian companies and global leaders in their respective sectors have joined forces to showcase the advantages of dual-layer laser cladding. This results from developing a high-speed, fully automated brake disc coating system for Stellantis. The first in a series of robotic-driven Rapid Coating Process cells was presented during the Stellantis Factory Booster Day, held in Turin on September 18th. By hard coating the raw brake discs with resilient steel and composite materials, the solution will enable Stellantis to significantly increase brake disc durability, reduce emissions pollution by up to 80%, and keep cycle times at a minimum. This will allow the automotive manufacturer to fully comply with the Euro 7 standard, which requires a 27% reduction in particle emissions from brake discs by the end of 2026. With a combined commitment to innovation that spans over 50 years, Comau and Prima Additive developed the robotic cell using a combination of advanced laser systems, high-speed robotic arms, additive manufacturing processes and safe powder management. Furthermore, the full integration of Comau’s robotic arms with Siemens SINUMERIK Run MyRobot allows the industry-standard software platform to directly control the robotic arm without needing external or embedded robot controllers. The modular system also allows maximum flexibility and productivity. Indeed, the cells are equipped with adjustable grippers that can handle different sizes of discs, from cars to trucks, to address evolving production mix scenarios. Finally, besides being highly versatile and energy efficient, the solution is characterised by a reduced overall footprint. Paolo Calefati, CEO of Prima Additive says “We believe that collaboration and innovation are the driving forces shaping the future of manufacturing.” “Our collaboration with Comau joins two companies with deep expertise in their respective fields to develop a truly cutting-edge industrial solution in automation and advanced laser systems for material processing. More importantly, the laser system developed for the brake disc coating application is one of the most profitable and sustainable cases of laser additive manufacturing/laser cladding technology applied in mass production for automotive. This solution not only contributes to improving the performance of automotive brake discs but also plays a crucial role in promoting sustainability by reducing the overall environmental impact of motor vehicles.” Pietro Gorlier, CEO of Comau says “This robotised solution represents a great example of innovation, led by two Italian companies who have developed advanced technologies to meet important sustainability targets.” “In working together to automate high-speed laser cladding safely, Comau and Prima Additive are helping meet a growing demand in Europe and beyond for flexible, turn-key solutions that will help reduce particle emission pollution in response to recent regulations. We're confident there is significant market potential for this type of solution.” The jointly developed Rapid Coating system is scheduled to be deployed at the Septfonds plant in France by the end of 2024, making Stellantis one of the first automakers to launch a fully automated line for the hard coating of brake discs in compliance with Euro 7 policy standards. /episode/index/show/mtdmag/id/34032190

Powerful lathe enables stainless broaching. 11/20/2024

Powerful lathe enables stainless broaching. Architectural ironmongery manufacturer Instinct Hardware has recently invested in a host of equipment that includes an Italian-built Biglia bar-fed, twin-spindle lathe with a ± 45 mm Y-axis turret having and 15 driven tools. Installed in the Stirchley factory where premium quality door knobs and handles, door stops, and accessories are manufactured, the latest turning centre was sourced in May 2024 from the Whitehouse Machine Tools. The company supplied the machine as a turnkey package with a bar feeding unit and a gantry-type system for unloading components onto a conveyor. This handling method was chosen to prevent damage to the components’ surface and preserve their aesthetic appearance. Whitehouse also supplied programs and tooling for producing two key components and their prove-out in Kenilworth, plus comprehensive training. Instinct Hardware products are either standard catalogue items or manufactured to bespoke designs and have been used in prestigious projects. These include the ongoing refurbishment of Citibank UK’s London headquarters, Google’s new headquarters in King’s Cross, various London Underground stations, the recent renovation of Wembley Stadium and Liverpool FC’s modern training centre. Until now, stainless steel has accounted for 80% of production, with the remainder mainly brass and bronze. However, an increasing amount of aluminium is being processed due to its easy recyclability. Director Nil Chohan says: “Since we moved to our current premises, we have been increasing our machining capacity to reduce our reliance on subcontractors. All of our lever handles require a square hole to be broached. This has always been done separately on a hydraulic press, as before the Biglia B 620 YS was installed, we did not have a rigid enough lathe.” “We bought the Italian turning centre specifically because it can broach our stainless steel handles, which Whitehouse demonstrated before we committed to the machine. So, we can now perform all operations in one hit rather than in five or six operations. It significantly reduces scrap rate by avoiding repeated manual setups and greatly speeds manufacturing time, enabling us to fulfil our promise of a 10 to 14-day order turnaround.” A case in point is machining a component assembled into a stainless steel, oval-profile, mitred lever handle. It previously required six machining operations from turning on a 3-axis lathe, milling and drilling on a VMC, broaching on a hydraulic press, further prismatic machining on a different VMC, slotting on yet another VMC and mitring on a bandsaw before welding. This consumed 15 minutes of machining time plus 10 minutes of handling and setup for each of the five additional operations. On the Biglia, the part comes off complete in 8.5 minutes, representing an eight-fold time saving, with the added benefit of eliminating work-in-progress and the potential damage to components. Nil Chohan needed a robust and powerful machine capable of broaching stainless steel, he was impressed by the specification of the B 620 YS, particularly the 30kW direct-drive, liquid-cooled main spindle motor offering 700Nm of torque. The lathe has boxways in the X and Y axes to promote rigidity and accurate machining, with a linear guide rail in the Z-axis for traverse speed. He says: “Reputation is hard to establish but even more challenging. Through hard work and endeavour, we have become a leading European manufacturer of bespoke architectural ironmongery. Today, our team is committed to continued investment and further developing our range and brand with an increased focus on sustainability of materials and logistics. We are constantly looking at new machinery like the Biglia to develop and enhance our offering whilst maintaining our passion to continue driving the company and our industry forward.” /episode/index/show/mtdmag/id/34032182

Hexagon and SEAT S.A. partner in digital transformation. 11/20/2024

Hexagon and SEAT S.A. partner in digital transformation. Hexagon, a world leader in digital reality solutions that combine sensors, software and autonomous technologies, has expanded its collaboration with the automotive manufacturer SEAT S.A. The deal builds upon a 25-year partnership working with Hexagon’s Manufacturing Intelligence division. The companies have signed a strategic agreement that aims to deepen the digital transformation of SEAT S.A, focusing on the digitalisation of vehicle components, the management of digitised information and advanced process simulation. This agreement will enable SEAT S.A. to optimise production and make decisions on process adjustments in real-time. Hexagon has successfully implemented SEAT S.A.’s measurement and quality control systems. Through the extended collaboration, the team will integrate a digital twin that applies metrology data with process simulations to predict outcomes and improve efficiency. The solution will use systems to digitise the car body and its components, manage their data and provide reports and analytics to drive efficiency and reduce costs. The collaboration is based on three fundamental pillars: the digitalisation of the vehicle’s manufactured parts, the management of digitised information and the simulation of processes. Under the new agreement, Hexagon’s PRESTO system will fully automate the high-precision 3D laser scanning of the entire body with high-speed robotic inspection. The second pillar is managing digitised information, which uses Hexagon’s eMMA data management, quality planning and analytics platform. This automatically captures metrology data and manages it in a standardised way. The centralisation of all 3D measurement data captured during the digitalisation process facilitates informed and efficient decision-making, allowing SEAT S.A.’s production and quality managers to monitor the condition of the parts and optimise quality in all assembly phases. The third key aspect is process simulation, which allows SEAT S.A.’s quality analysts to accurately predict problems and optimise critical vehicle manufacturing processes such as part alignment, assembly and subsequent welding operations. Thanks to Hexagon’s simulation solutions, SEAT S.A. can optimise production and adjust the production settings using a virtual prototype of the product, speeding up the process of fine-tuning production methods used in series manufacturing. This capability translates into a significant reduction in costs, a reduction in material waste, and an improvement in time-to-market for the new vehicle models. Josh Weiss, president of Hexagon’s Manufacturing Intelligence division, says: “We're committed to helping SEAT S.A. stay at the forefront of the automotive industry by implementing innovative digital processes that transform agility in manufacturing and take control of quality from the start. By combining technologies such as automated quality inspection, connected quality workflows and virtual manufacturing, SEAT S.A. can supervise each production stage with significant savings in time, material waste and costs”. Daniel Cortina, Director of Quality at SEAT says: “At SEAT we are at a time of unprecedented transformation for our company towards smarter, more connected and efficient production, which involves the digital transformation of our production processes. Now, we'll acquire data about the quality of our parts faster and more accurately, and will also be able to improve manufacturing performance with them. This predictive approach to quality allows us to improve our customer satisfaction and significantly reduce the materials used in the manufacturing process, reinforcing our commitment to sustainability.” /episode/index/show/mtdmag/id/34032174
