The JP Performance titanium rim is a globally unique project. A rim made of Grade 5 titanium – a material otherwise used in aerospace – was manufactured for the legendary Jaguar E-Type. It took over 160 hours of machining time to transform the 400 kg raw block into the finished 18 kg rim. The project began through a collaboration between Ladermanufaktur GmbH and JP Performance. We were directly involved as a tooling partner and played a decisive role in the manufacturing process with our high-performance titanium milling cutters.

Material & starting point: Grade 5 titanium

The journey to creating JP Performance titanium rims begins with a solid 400 kg block of titanium. Grade 5 titanium impresses with its high strength, corrosion resistance, and low thermal conductivity. These material properties make machining particularly challenging. Without the milling cutters specially developed for titanium, the transformation from raw block to high-end rim would not have been possible. Our tools ensured maximum stability, process reliability, and precision.

Manufacturing & machining: 160 hours of high-end machining

The production of the titanium rim is a prime example of high-end machining. Creating each rim from a 400 kg block of titanium requires over 160 hours of machining time. The process uses the following:

• 5-axis milling, including simultaneous machining
• CAM software: SolidCAM with strategies such as iMachining 2D/3D
• Machining methods: High-speed machining

Developed for extreme conditions, our titanium milling cutters ensure precision when machining complex geometries. Tool lengths of up to 400 mm placed special demands on stability and vibration damping.

Design & aesthetics of the titanium rim

The rim design is turbine-like, with deeply machined spokes and clearly defined contours. It combines the classic elegance of the Jaguar E-Type with state-of-the-art high-end manufacturing. Tailoring each contour to the capabilities of the tools and the machining strategy ensures precision. The result is technical perfection and aesthetics in a unique piece.

Technical challenges in titanium machining

Experts consider titanium a particularly challenging material for machining. The deep pockets and long milling cutters (up to 400 mm) create vibration risks and stability problems. The high strength and low thermal conductivity increase the risk of tool breakage and material overheating. In addition, the enormous material removal from the 400 kg raw block to the final weight of 18 kg must be precisely controlled.

Our solution consisted of optimized tool paths, adaptive cutting parameters, and continuous process monitoring. Every decision was based on our direct expertise in the manufacturing process.

In machining, nothing works without the right tool. If you want to manufacture a component, you need a cutting tool that is suitable for the task. We rely on modern CAD/CAM systems right from the planning stage – in particular CAD/CAM grinding – to make processes more efficient and easier to plan. The digital process chain has long been a reality at our HAM Performance Center (HPC) too.

We usually fall back on tried-and-tested standard solutions. Catalog tools are readily available and have proven themselves reliable in many applications. But sometimes these tools reach their limits. Not every machining operation can be carried out economically or technically in a sensible manner using these tools.

What then? The answer often lies in customized solutions. Special tools offer exactly what standard tools cannot. They are individually tailored to the component and enable machining operations that would otherwise not be possible.

What often makes us hesitate when it comes to special tools

Special tools offer many advantages. Nevertheless, the decision to opt for a customized solution is not always easy. The most obvious reason is the price. Especially with smaller quantities, the question quickly arises as to whether the investment is worthwhile at all.

Added to this is the necessary expertise. Complex geometries and special requirements call for technical understanding and experience – not every company has this available in-house. Delivery time also plays a role. Special tools first have to be developed and manufactured, which takes time. The longer it takes for the tool to arrive, the later the component can be produced.

Another point is the coordination effort involved. Requirements must be discussed, drawings checked, and queries clarified. This ties up resources and costs time – a real bottleneck, especially in tight project phases.

And yet, those who opt for special tools have a lot to gain. Customized solutions enable machining operations that would not be possible with standard tools. They save time, improve quality, and make processes more efficient.

Why special tools are worthwhile

Combination solutions allow several machining steps to be combined. This saves machining time and reduces tool changes – a clear advantage in terms of non-productive time. At the same time, the risk of misalignment or inaccuracies is minimized, as machining is carried out in a single operation. The result: higher quality.

Space is also saved in the tool magazine, which increases flexibility – especially when changer space is limited. All these factors contribute directly to cost-effectiveness. The additional expense is quickly recouped, especially with complex or recurring components.

And what about the typical concerns? The costs are offset by efficiency and precision. The necessary specialist knowledge is simplified by the ISBE Sketcher and standardized in accordance with DIN standards. The coordination effort is reduced by digital processes. And thanks to our HAMmer FAST LANE, long delivery times are a thing of the past – complex special tools are designed and manufactured within minutes.

More than just the right tool

A good tool alone is not enough to manufacture a component efficiently and precisely. The entire process is crucial – and it begins long before the first chip is cut.

Many components interact during production. The machine, clamping, CAD/CAM programming, cooling, and tools must be perfectly coordinated. Only when all components work together harmoniously can a stable and economical overall process be achieved.

There is also more to the “Tool” module than meets the eye. After all, what makes a normal tool a perfect tool? It’s the details – from the geometry and coating to the coordination with the material and machining strategy.

What makes a tool perfect

A perfect tool starts with the right material. The first crucial point is selecting the appropriate carbide. Carbide is a sintered material whose main components are tungsten carbide as the hard material and cobalt as the binder. Depending on the intended use, other carbides are added to specifically modify the properties.

Due to the high sintering temperature of around 1500°C, carbide is naturally extremely heat-resistant – and, as the name suggests, very hard. The grain sizes range from less than 0.2 µm in the nano range to over 6.0 µm in the coarse grain range. This means that the mechanical properties also vary greatly. At HAM, we generally use carbide grades ranging from ultra-fine to fine grain in order to achieve an optimal combination of hardness, toughness, and wear resistance.

Bevor das Werkzeug beschichtet wird, durchläuft es unsere eigene Oberflächenbehandlung: das Hybrid Surface Finish (HSF). Dabei wird der Spanraum poliert, um den Späneabtransport zu verbessern, und die Schneidkante gezielt verrundet – für mehr Stabilität und längere Standzeiten.

Before the tool is coated, it undergoes our own surface treatment: Hybrid Surface Finish (HSF). This involves polishing the chip space to improve chip removal and specifically rounding the cutting edge for greater stability and longer service life.

Various hard coatings are used, depending on the application and material. Examples include:

• TiAlN / TiSiN: Multilayer or nanocomposite
• TiAlN: Monolayer or multilayer
• AlTiN supernitrides: Nanocomposite or nanolayer
• ta-C (DLC): Tetrahedral, amorphous carbon layer – also known as “rainbow layer”

A clear example of this is dome polishing. This technique makes the structure of a TiAlN-based multilayer coating visible—a process that not only looks impressive, but also provides valuable technical insights.

Grinding the perfect tool – a process with many components

A perfect tool is not only the result of good materials and precise geometry. Grinding itself is also a complex process in which many factors must interact.

It all starts with selecting the right grinding wheels. This is followed by programming – a step that often takes a lot of time. With CAD/CAM Grinding, tools can be designed quickly and easily and tracked digitally throughout the entire process. Parameters that have already been entered when preparing the quote do not need to be entered multiple times. This saves time and reduces sources of error.

The grinding machine must also reliably implement the required process parameters. And to ensure the right quality, precise measurement technology is needed. Modern systems measure the tool during the process – with micrometer precision—and compensate automatically. This minimizes the influence of human error and ensures a stable, uninterrupted process.

To ensure that this process runs smoothly, all of our partners work hand in hand:

• Vollmer VGrind infinity as a flexible grinding machine
• ISBE Sketcher for tool design
• BLUM laser measuring bridge for in-process measurement
• and HAM‘s tool expertise

Implementation in practice: From component to solution

Unser Beispielbauteil: ein pneumatischer Zylinderboden. Für das G1/8-Gewinde fehlten Wechslerplätze – die Lösung war ein Sonder-Stufenbohrer, der vier Operationen auf zwei reduziert.

Our example component: a pneumatic cylinder base. There was not enough space for the G1/8 thread – the solution was a special step drill that reduced four operations to two.

Instead of centering, drilling, countersinking, and cutting, machining is now performed in a single operation. The core hole and countersink are combined, and the thread is milled and checked. This saves time, reduces tool changes, and increases efficiency.

Key technical data for the component:

• Material: EN AW-2007
• Dimensions: 110 × 110 × 40 mm
• Machine: Hermle C12U
• Control: Heidenhain TNC 640
• Workpiece clamping: LANG zero point clamping system
• Tool clamping: Schunk HSK-A63
• Cooling: MMS, KSS

Technical data of the special tool:

• Material: VHM K40 10
• Dimensions: Ø12 × 103 mm
• Grinding machine: Vollmer VGrind infinity LINEAR
• Control: NUMROTO
• Workpiece clamping: Schunk hydraulic expansion chuck

Practical implementation: Live demonstration in the workshop

Our compact video shows how all the process components described interact in reality. From the digital design of the special step drill to precise grinding and final use on the pneumatic cylinder base—every step is part of a well-thought-out, efficient, and proven process.

The live demonstration clearly shows that with the right combination of CAD/CAM technology, machine expertise, and tooling know-how, even complex requirements can be implemented quickly and economically.

Turning, milling, drilling, reaming, threading, measuring – all in a single integrated process. Sounds like the future, but it has long been a reality in modern manufacturing companies. Complete turning-milling machining combines high-precision machining steps into an efficient process that saves time, reduces errors and sustainably improves processes.

This is exactly what we demonstrated in our workshop. How CAM programming, tool strategy and machine concept combine to form a coherent solution. From the digital model to the finished component. With real workpieces, real machining strategies and real results.

In this article, we take you on a practical journey. You will learn how we transform complex requirements into clear solutions. And you will see why tool selection, CAM system and process thinking are now more decisive than ever for quality and competitiveness. Welcome to the world of complete turn-mill machining. Welcome to the “Drevolution“.

From past challenges to today’s precision

Anyone involved in modern turn-mill complete machining today should understand the hurdles that had to be overcome in the past. The production of complex components often began with the creation of elaborate 2D drawings. Every line, every dimension had to be interpreted precisely. This often resulted in ambiguities that developed into real problems in production.

Programming was also carried out directly on the machine. This was not only time-consuming but also blocked valuable machine running time. Any manual input error could lead to downtime. In addition, tools were often not managed centrally. Whether a suitable tool was available or even suitable at all could often only be determined during set-up. In many cases, the first part produced only served as a test piece – rejects were almost inevitable.

Digital thinking. Made efficiently.

Today, things look very different. Modern production begins with a well thought-out 3D model, for example in Step or SolidWorks format. It is no longer programmed directly on the machine, but using powerful CAM systems that also enable simulations. Even before the first cut is made, it is possible to check how the tool will behave in the installation space, whether there are any collisions and whether all the machining steps mesh properly.

Tool data, geometries and cutting values are available centrally. Customers are increasingly demanding digital twins to supplement their own systems, for example for CAM programming or collision-free assembly planning. Tool management is thus becoming an integral part of a digitized, end-to-end process.

At HAM Präzision, we live exactly what we teach in our workshops. Our goal is not only to understand processes, but to consistently optimize them. Error prevention, maximum process reliability and short production times are our daily focus. After CAM programming, we can go straight to the machine – without rejects, without time-consuming set-up, without long searches for the right tool or room for interpretation of drawings. This end-to-end process is a decisive advantage, especially in our one-off and small series production.

The advantages speak for themselves: machine downtimes are avoided, tools are centrally managed and available at all times, manual programming errors are a thing of the past. The result is an end-to-end manufacturing process that combines maximum precision with impressive efficiency. What we are experiencing is not a slow change, but a noticeable further development in machining. A new way of thinking. A real turning revolution.

What “Drehvolution” means to us

For us, “Drehvolution” describes a holistic approach that begins long before the first chip – namely, with the design of the tool. In this early phase, we lay the foundation for precise, economical and consistent production. Our goal is to design each process step in such a way that maximum precision goes hand in hand with high efficiency. This includes the consistent use of digital tool data and well thought-out process planning right from the start.

The demands on production are constantly increasing. Customers expect shorter delivery times, consistently high quality and reliable prices. At the same time, qualified personnel are becoming increasingly rare. We meet these challenges with innovative solutions that closely interlink and coordinate planning, production and tool management.

Complete machining as the key to efficiency

Modern complete turning-milling machining combines all work steps – turning, milling, drilling, threading, deburring and measuring – in a single machining center. The process runs continuously with just one reclamping, supported by automated loading and unloading systems such as bar or gantry loaders for a smooth material flow.

A look at the time involved shows the progress: whereas modeling, drawing creation, checking and programming often used to take more than 800 minutes, it now takes around 500 minutes with CAM programs and digital tool data. Manual programming and downtimes in particular are eliminated, saving several hours of time.

This efficiency is the result of high-performance CAM systems in combination with central tool management. Tools are digitally recorded and available at all times, minimizing machine downtimes and significantly reducing sources of error.

Additional challenges and solutions

In addition to technical implementation, modern manufacturing presents numerous challenges that can be specifically addressed through integrated turn-mill complete machining. In terms of economic efficiency, every minute counts today. The time from quotation to finished product must be kept as short as possible. At the same time, fewer personnel are employed, but they have to take on more responsibility and tasks.

Competitiveness is also under pressure. Delivery deadlines must be met, prices must be calculable and processes must be planned. Automated tool management provides support here, as it ensures that all operating resources are available at all times. This avoids unnecessary machine downtime due to missing tools.

Digitalization offers enormous potential, but is not yet fully exploited in many companies. Although industry four point zero is frequently mentioned, full implementation often fails due to limited financial resources, a lack of specialists or the complexity of the systems.

Added to this is the increasing time pressure in day-to-day business. Delivery times are getting shorter and customers are making changes at ever shorter notice. Sometimes adjustments even reach us during ongoing production. Without digital models and precise CAM programming, such changes would be almost impossible to implement realistically.

And finally, the focus is on quality. Optical and functional repeatability is essential today. Automated deburring ensures that every manufactured part meets the exact same requirements and remains constant in terms of form and function.

From digital model to the integrated process

The work begins on the screen long before the chips start flying. The basis for stable complete turn-mill machining is a complete 3D model of the component. This can be integrated quickly and directly into SolidWorks and forms the basis for CAM programming. This allows machining strategies to be simulated, checked and specifically adapted long before the workpiece reaches the machining center.

However, a challenge arises with models that are not designed for mid-tolerance. This is because the CAM system implements exactly what the model specifies. For example, it does not automatically recognize whether a diameter is between plus zero point one and plus zero point two. In such cases, we therefore specifically program a grinding allowance that appears to be a deviation in the simulation, but corresponds exactly to the target dimension in actual production.

For consistent and precise complete machining, all components must be coordinated with each other. The machine with its kinematics and cooling functions, the workpiece clamping, the tool holder, the CAM strategy, the selected cutting values, the type of cooling and, of course, the tools used themselves. Whether PCD or solid carbide, whether with special cutting edge geometry, coating or coordinated helix angle – every detail contributes to process reliability and repeat accuracy. A stable, reproducible production process can only be achieved when everything works together.

Turning-milling complete machining in live application

This interaction was demonstrated live during our workshop. The focus was on the complete machining of a base body for a PCD tool made of steel. From cutting, turning, milling, drilling, reaming and threading to automatic deburring and measuring, every step was carried out directly on site.

A Mazak Integrex i 100H S, equipped with the Mazatrol control system, was used. For workpiece clamping, we used gripper jaws on the main spindle and specially machined jaws on the counter spindle. Tool clamping was ensured by Capto C6 in combination with hydraulic expansion technology. Classic emulsion ensured reliable cooling.

A particular highlight was the integrated measurement during the machining process. The TC62 3D touch probe from Blum Novotest was used in this configuration for the first time. The measurement data was processed directly and fed back to the machine for correction. The result was a consistently precise component – with no manual reworking and no loss of time.

The CAM programming was implemented with SolidCAM. Among other things, powerful strategies such as iMachining were used, which enable uniform machining with optimum loading of the cutting edges. The tools we used were precisely matched to the material and the machining task. The cutting material, cutting values, geometry and surface technology interlocked perfectly.

The result was a functional, dimensionally accurate basic body – completely manufactured in a single clamping operation. Fast, safe and with maximum precision.

Watch the video to see what this process looks like in reality. Immerse yourself in the practice of modern turn-mill complete machining – precise, efficient and live.

Aluminum is omnipresent. We encounter it in vehicle bodies, aircraft structures, machine components, packaging and in many industrial applications. The reasons for this are obvious: the material is light, malleable, corrosion-resistant and impresses with its excellent conductivity. However, it is precisely this diversity that poses particular challenges for manufacturers. This is because aluminum machining is anything but a matter of course.

Depending on the alloy, strength and structure, it reacts very differently to machining processes. Chip sticking, built-up edge formation and abrupt tool wear are just some of the typical side effects. The challenges often lie in the details and the path to a stable, efficient process is rarely straightforward. What makes the decisive difference only becomes apparent when you delve deeper.

From lightweight to high-performance: What makes aluminum so attractive for machining

As a material, aluminum has an exceptional combination of technical properties that make it particularly attractive for machining. Aluminum naturally forms an oxide layer that protects it from corrosion, and anodizing can further enhance this protection — a clear benefit in harsh environments or for demanding surface requirements. At the same time, aluminum conducts heat and electricity very efficiently: with around 60 percent of the thermal conductivity of copper and an electrical conductivity of around 62 percent at only a third of the weight, it is ideal for lightweight, high-performance components.

The material also offers advantages both visually and functionally. It reflects up to 90 percent of thermal radiation and 80 percent of light, making it predestined for use against light and thermal radiation in applications such as roofing and heat shields for motor vehicles. In terms of sustainability, it scores highly with its excellent recyclability. Recycling uses only a fraction of the energy while maintaining full quality and strength. Furthermore, it generally does not require any additional protective coating, as simple processes such as brushing or shot blasting are usually sufficient. However, if increased protection is required, additional surface treatments such as paints or electrochemical treatments (e.g. anodizing) can be applied.

Light, strong, versatile – ideal conditions for machining

A decisive factor for aluminum machining is the excellent ratio of weight to strength. This makes the material ideal for lightweight, robust constructions, such as in vehicles or aircraft. It also impresses with its uncomplicated processing: it can be produced in almost any desired thickness. Its easy machinability – for example through turning, milling, or grinding – and the high processing speed also make production more economical. Furthermore, it is highly formable and can be processed into fine threads or complex shapes without breakage. Despite its lower ductility compared to copper, its low density and low melting point enable the flexible production of a wide range of products such as sheets, tubes or rods..

Aluminum also shows its strengths at low temperatures: it does not become brittle, but stronger, and remains corrosion-resistant. It is also non-magnetic, which makes it ideal for shielding antennas and computer panels. Anyone who wants to machine aluminum is working with a material that is not only light and conductive, but also robust, sustainable and extremely versatile. Provided you know its characteristics and use the right precision tools, such as those developed by HAM.

Not all aluminum is the same, and that makes all the difference

Aluminum is a real lightweight with amazing strength. Compared to other materials, aluminum is in the middle range in terms of strength. However, when its density is taken into account, it clearly stands out and even surpasses steel. It is precisely this ratio that makes it so attractive for lightweight construction. Aluminum has played a key role in automotive engineering, aviation, and mechanical engineering for many years.

But as versatile as the material is, it also behaves differently when it comes to machining. Because not all aluminum is the same. In addition to pure aluminum, there are a variety of aluminum alloys with their very own properties. While pure aluminum is very soft and only has low strength, alloys usually have significantly better prerequisites for aluminum machining. A distinction is made between wrought alloys and cast alloys. Both types are basically machinable but require a differentiated approach.

In practice, aluminum alloys are divided into three classes. Class one comprises very soft materials with low strength. These often produce greasy chips during machining, which stick to the tool and lead to the formation of built-up edges. Class two describes materials with increased strength in the range of around 300 to 600 Newtons per square millimeter. These alloys are significantly more stable and lead to fewer built-up edges. Class three stands for free-cutting materials and wrought materials with chip-breaking additives such as lead. These additives ensure clean chip formation and significantly reduce the tendency for built-up edge.

The biggest challenges in machining aluminum

At first glance, aluminum seems like a dream partner for machining. Light, easy to shape and clean to process. But when you stand at the machine, you quickly realize that this material also has its peculiarities. In particular, the sticking of chips and the stubborn built-up edge make even experienced machining professionals break out in a sweat. Especially when milling aluminum, these effects can have a negative impact on dimensional accuracy, tool life and surface quality.

One key to successful aluminum machining lies in high-speed machining. Combined with a carefully selected cooling lubricant strategy, many problems can be avoided from the outset. Aluminum generates significantly lower cutting forces than steel during milling, often only about a third. This property allows high cutting speeds, but at the same time requires consistent control of the chip flow.

To ensure process stability, it’s crucial to remove chips from the cutting zone quickly and efficiently. This requires special tools for aluminum with smooth, slippery surfaces that prevent sticking and actively remove the chips. Milling cutters with a lower number of teeth than tools for steel are also characteristic. This design significantly improves the chip flow. Coordinated coating solutions, when integrated into the process, reliably control even sticky aluminum chips.

These are the factors that really matter when machining aluminum

If you want to machine aluminum reliably and precisely, you have to master the interaction of many components. It starts with the machine itself. It should not only work stably, but above all be prepared for the use of modern cooling lubricant solutions. Systems like the AerosolMaster 4000 ATS from Blum-Novotest enable highly efficient minimum quantity lubrication by precisely dosing a fine film of lubricant. At the same time, the machine must support internal and external cooling options and allow clean adaptation to dry machining, emulsion or MQL.

Another cornerstone of aluminum machining is the clamping. The tool holder and workpiece holder must grip precisely to avoid vibrations and ensure clean chip formation. In MQL machining, the cooling channel must be optimally positioned to ensure effective performance. This is the only way to ensure reliable chip removal without leaving any residue in the machining zone. When drilling, for example, a special clamping structure with a central lubricant supply via the holder can be crucial.

And let’s not forget the digital side of the process. CAM programming has a massive impact on efficiency and tool life. Those who rely on well thought-out strategies and smart adjustments to the cutting values not only save time but also ensure uniform surfaces. Those who rely on well-thought-out strategies and smart adjustments to cutting parameters not only save time but also ensure consistent surfaces. Technology such as SolidCAM‘s iMachining, in combination with optimized cutting data, enables a constant load and reduces thermal peaks at the same time.

However, the optimum machine, perfect clamping and intelligent programming only unfold their full potential in combination with the right tool. This is because the cutting material, cutting values, tool geometry and surface technology determine the cutting quality and process stability, especially with aluminum. Therefore, it’s worth taking a closer look at the specific requirements of tools for aluminum machining.

What makes our tools so special when machining aluminum

What truly makes a tool for aluminum machining outstanding isn’t just the cutting material used or a single design feature. It’s the interplay of sophisticated materials, sophisticated geometry, and state-of-the-art surface technology that makes the decisive difference.

When it comes to cutting materials, we specifically focus on two proven materials: polycrystalline diamond (PCD) and solid carbide. PCD tools are the first choice for machining abrasive aluminum alloys with a high silicon content or for very high-volume production combined with long tool life. They are characterized by exceptional wear resistance and deliver consistently high surface qualities – an advantage that is particularly in demand in sensitive sectors such as aviation or automotive engineering.

Solid carbide tools, on the other hand, score points for their versatility. They are ideal for smaller series or for processes that require a high degree of flexibility. Their advantage lies not only in their good cutting performance, but also in the fact that they are generally more cost-effective than PCD tools. They are also a particularly good choice when machining other materials in addition to aluminum, as they are suitable for a wider range of applications.

Geometry and surface technology as the key to performance

The tool geometry is decisive for the quality of machining. Our milling cutters have precisely ground cutting edges, a sharp point and defined cutting edge rounding. Internal cooling channels enable an efficient supply of cooling lubricant, while flat helix angles and uneven helix pitches minimize vibrations and improve chip breaking at the same time. The chip chambers have also been specially designed for aluminum alloys to ensure reliable chip evacuation. The strength of our tools is particularly evident when drilling: The specifically designed MQL chamfer on the cutting edges optimally supports aerosol lubrication and makes the tools particularly efficient in combination with modern MQL systems.

A decisive contribution to tool performance comes from surface technology. In order to meet the high demands placed on PCD and solid carbide tools, HAM has developed Hybrid Surface Finish, or HSF for short, a hybrid and technologically highly complex solution. This produces a defined surface finish while simultaneously homogenizing the cutting edge. In combination with a precisely coordinated grinding quality, this creates a high-performance overall system.

For tools with shank diameters up to 32 millimeters, we apply PVD hard coatings such as TiN, TiAlN, TiNAlOx, or AlOx. The HSF process ensures mirror-smooth surfaces on carbide and PCD, for diameters between 0.5 and 32 millimetres. Depending on the application, defined cutting edge preparations of 4 to 20 µm are achieved. The tool’s meticulous design comes to life only when all its properties are combined optimally, unleashing its full potential.

Machining aluminum – exploiting potential, mastering challenges

Machining aluminum is more than just a routine production step. Different alloys, complex material properties and process-specific requirements demand a high level of expertise. If you want to manufacture economically and reproducibly, you need to have the entire machining process under control – from material selection and the optimum cooling strategy to the precise coordination of machine, clamping and CAM programming. The high quality that modern applications require today can only be achieved if all factors are interlinked.

With our many years of experience in aluminum machining and our highly developed tool solutions – from polycrystalline diamond to finely tuned solid carbide – we not only offer individual components, but also sophisticated overall solutions. Technologically leading geometries, specially developed surface treatments such as HSF and perfectly coordinated coating concepts make our tools the first choice for demanding production tasks. Anyone who wants to machine aluminum efficiently and reliably benefits from our expertise down to the smallest detail.

Practical application

In our workshop “Zerspanung ALU – Best of HAMmer”, we showed how theory and practice can be optimally combined. We machined a component made from the high-strength aluminum alloy EN AW-2017A. This alloy is an age-hardenable material that develops its full strength potential after targeted heat treatment, such as solution annealing with subsequent cold ageing. It plays a key role in the aerospace and defense industry in particular due to its high mechanical strength and good machinability.

The workpiece, measuring 200 x 100 x 25 millimetres, was machined on a Hermle C12U, controlled by a Heidenhain TNC 640. We used a zero-point clamping system from LANG to ensure reliable and repeatable clamping. In combination with a precise tool holder from Diebold based on HSK-A63, a high level of stability was guaranteed.Milling was performed with targeted use of minimum quantity lubrication and classic cooling lubricant, ensuring optimal chip removal and maximizing tool life based on the machining area.

When everything works together, it shows how powerful aluminum can be in the right environment.
