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
• Measuring instruments: BLUM TC 76-N, BLUM LC50

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.

Imagine a factory where gears not only mesh, but where ideas interweave to create groundbreaking solutions. A place where technology doesn’t stand still, but rather storms forward – faster, more precisely, more efficiently. This is exactly what our HAM showroom is. We launched it four years ago to provide a real insight into the digital process chain and to show what digital manufacturing looks like today and what it could look like in the future. Not a theoretical construct, but a functioning system that ranges from the first digital tool model to machining on the machine.

For us as a tool manufacturer, one thing is clear: precision tools are at the heart of every production process, but fully networked production requires more than just excellent tools. A digital process chain requires the perfect interplay of different components, from tool production to machining. That’s why we set up the HAM showroom together with strong partners. What started small is now a dynamic network that is constantly growing. Year after year, new partners join us to expand our processes with state-of-the-art technology and keep them up to date. After all, digital transformation is not a one-off project, but a continuous development process and this is exactly what our showroom reflects.

Networked production: the digital process chain

Modern manufacturing is more than just production; it begins long before and doesn’t end with the last chip. The digital process chain maps this entire process: from the initial tool model creation according to DIN 4000 to the final machining on the machine. A tool and other things, such as materials, operating resources, etc., go through several process steps in every company.

However, it is not just the physical components that pass through various stations; data and information must also flow seamlessly. Every manufacturing process spans several areas: Process design and simulation, procurement and storage, tool preparation and setup and finally, actual production. And this is precisely where smart manufacturing comes in. After all, what use is a perfectly assembled tool in the machine if essential data on measured values or tool life is missing? The answer is simple: nothing. Without precise information, valuable time is lost and with it efficiency and quality.

The digital process chain takes a holistic approach to production. It not only considers the moment when the tool meets the machine, but also all upstream steps. This is because the entire process is laid out in what is known as work preparation. And this is precisely where there is enormous potential for savings: less time, reduced costs and increased production quality.

What advantages do we achieve with our digital process chain?

Any production is only as strong as its weakest link. A single high-precision tool is not enough if the rest stagnates. Manufacturing is not a stiff construct. It lives, evolves and faces new challenges. This is precisely where our digital process chain comes in, as an invisible control center that intelligently links data, machines and processes. The result? Less downtime, more efficiency, maximum throughput.

Instead of transferring data manually and risking errors, seamless data consistency ensures that all information arrives exactly where it is needed. From the first planning step to final processing, all relevant values flow seamlessly through the entire process. Manual transfers and error-prone intermediate steps are a thing of the past. This not only reduces the risk of misunderstandings, but also the time spent on unnecessary corrections.

But data alone does not increase productivity. At the same time, machine time is used more efficiently. In the past, programming used to be done directly at the machine. This was a laborious and time-consuming process that resulted in valuable lost production time. Today, CAM systems perform this task in advance, while tools such as Vericut simulate the NC code before the first chip is cut. This not only prevents downtime, damaged tools, costly collisions and unusable parts, but also saves lengthy run-in processes and wasted material.

More machine running time, less downtime

At the same time the digital process chain ensures leaner processes. Shorter programming and set-up times, a reduced variety of tools and optimized stock levels ensure faster processes and lower costs. Everything is precisely coordinated, unnecessary steps are eliminated and the entire production runs smoothly like precisely timed clockwork.

Another often underestimated factor is the prevention of search times. Anyone who has ever spent precious minutes trying to find the right tool knows how quickly this time adds up. However, well thought-out tool management systems such as Toolbase solves precisely this problem. Every tool you need is available exactly when you need it – without tedious searching and unnecessary downtime.

With all these advantages, the digital process chain makes the difference between a production that works and one that is truly efficient. Fewer errors, shorter downtimes, lower costs and production that is ready for the demands of the future today. But what exactly does our digital process chain look like now?

Our digital process chain in action

In our showroom, we demonstrate how the digital process chain is perfectly integrated from the first step of planning through to final production. The starting point is tool planning with the ISBE Sketcher software. We use this innovative solution to design and plan special tools in 2D and 3D. In addition, digital twins of the tools are created that can be used throughout the entire production process. These enable seamless further processing of the data throughout the entire process chain.

We use Tooltracer for error-free management and integration of tool data. This web-based database guarantees error-free tool master data records from a wide range of tool manufacturers and transports the data via interfaces to all common shop floor systems, such as WinTool. The result: significant time savings of up to 80% when creating and adapting tool master data.

Once all the required tools have been imported into WinTool, they are virtually assembled with a suitable tool holder. The measuring programs for production are already defined and written in the work preparation phase. The combined tool list is then seamlessly transferred to the CAM program via an interface. This eliminates the need to manually create individual tools, which speeds up the manufacturing process considerably and allows programming to begin immediately.

SolidCAM‘s patented iMachining technology enables cycle times to be reduced and tool life to be extended. Thanks to a wide range of simulation options, you retain control of the programmed tool path at all times. The generated NC code is stored together with relevant production data in a digital NC folder. This means that the process is theoretically designed and can be transferred to production on the shop floor.

From theory to practice: transferring data to production

All relevant production data, such as measuring programs or NC codes, can now be transferred to the machine control system. The automatically generated loading list shows the storage locations of the tools so that the required components can be removed quickly and without errors. Thanks to the barcode scanning system, the removal is documented and the system automatically updates the stocks. If reordering is required, this is done automatically to avoid expensive downtimes.

The TOOLFIX system from Schunk guarantees safe assembly of the Schunk toolholders and HAM tools. For the subsequent measurement of the missing tools, the measuring instruction sent by WinTool is called up in the Zoller DNC system. The tools are measured fully automatically using the venturion 450 CNC setting and measuring machine and the data is transferred to the machine without errors and with process reliability. The tool magazine locations are updated virtually to ensure complete traceability.

After selecting the NC code, machining begins. The TC52 touch probe from Blum-Novotest determines the workpiece zero point of the raw material before high-precision HAM carbide and diamond tools in Schunk tool holders go to work. Air, emulsion or the innovative minimum quantity lubrication with the AerosolMaster from KNOLL ensure optimum cooling. The LC50-DIGILOG from Blum-Novotest enables tool measurement and monitoring directly on the machine. Deviations from the target value are compensated for fully automatically. The measurement report created can be clearly assigned to each finished component. The finishing touch is provided by the compact C12 5-axis machining center from Hermle, which produces cubic parts weighing up to 100 kilograms with maximum efficiency.

Practical application: The digital process chain in live machining as part of our workshop “The HAMmer Smart Factory” on March 19, 2025

Der Beitrag The path to smart manufacturing: The digital process chain live at our workshop! erschien zuerst auf HAM Präzision.

The manufacturing world is at a turning point. With Industry 4.0, automation and intelligent production processes, the entire structure is changing – faster, more efficiently and more precisely than ever before. However, technological progress not only brings new opportunities, but also significant challenges: High investments, security risks in IT and the complex integration of new systems into existing structures are slowing down many companies.

Despite all the hurdles, digital transformation is no longer just a nice extra feature, but a decisive factor in remaining competitive. Companies that rely on networked production landscapes, smart maintenance concepts and digital processes benefit from increased efficiency, reduced downtimes and optimized quality assurance. But where do you start? How can proven processes be made fit for the future? And how do you manage to use digital innovations without losing flexibility?

These questions are groundbreaking and the answers to them could determine which companies remain at the top in the long term and which lose out.

The smart factory: networked production

Industrial production has undergone a profound transformation in recent years. Industry 4.0 marks the dawn of a new era in which machines, sensors and intelligent software interact seamlessly to make manufacturing processes not only more efficient, but also more flexible and predictive. The “smart factory” is not just a fad, but the consistent further development of modern production technologies. All processes are digitally networked so that data can be recorded, evaluated and used immediately for optimization in real time – an essential prerequisite for adapting quickly to dynamic market requirements.

In this digitalized environment, machines no longer act as isolated units, but as intelligent nodes in a finely tuned network. Through the use of IoT (Internet of Things) technologies, production systems communicate with each other continuously, coordinate processes autonomously and identify potential bottlenecks before they occur. The potential of this development is particularly evident in machining technology: machine tools are now able to diagnose wear at an early stage and independently initiate maintenance measures to avoid unplanned downtime – a principle known as “predictive maintenance“.

The digital transformation is no longer an optional addition, but an integral part of future-oriented manufacturing. According to the German Federal Ministry for Economic Affairs and Climate Protection, 95% of companies now recognize Industry 4.0 as an opportunity. In fact, more than half are already using Industry 4.0 applications. ¹ No wonder, as it not only increases efficiency, but also raises quality standards to a new level. Companies that take the step towards the smart factory rely on the intelligent integration of automation and networking and thus secure a decisive competitive advantage. In an increasingly networked economy, these technologies are the key to remaining competitive in the long term and preparing for future challenges. Those who make targeted investments in digital production strategies today are laying the foundations for sustainable, adaptable and future-proof production that meets the growing demands of the market.

More efficient, smarter, cheaper: the biggest opportunities of digital manufacturing

Digitalization is opening up completely new opportunities for the manufacturing industry. Not only can processes be made more efficient and cost-saving, they can also be controlled more precisely. Automation, networked machines and data-driven processes ensure that production processes run faster and more smoothly. Companies that take advantage of these digital opportunities benefit from smoother processes and a clear competitive advantage.

Automation is a key aspect of this. It replaces or supplements manual processes in order to increase productivity and precision. Intelligent systems and machines take over repetitive tasks, reduce manual intervention and minimize sources of error. At the same time, networked sensors provide valuable real-time data that can be used to continuously adapt and optimize processes. This helps to identify bottlenecks at an early stage, make better use of resources and shorten production times.

Digitalization also brings major benefits when it comes to maintenance. Instead of only repairing machines when they break down, intelligent sensors continuously record the condition of the systems (predictive maintenance). They detect wear and tear at an early stage and give a timely signal for upcoming maintenance. This not only reduces expensive downtimes, but also extends the service life of the machines and saves maintenance costs in the long term.

Not forgetting quality control. Digital measurement technology and AI-supported analyses detect even the smallest deviations in real time. This reduces waste, reduces reworking and ensures that the end products are of a consistently high quality. This is particularly important for companies that want to produce economically and sustainably.

Ultimately, digitalization is not just about efficiency. It fundamentally changes how production takes place and makes manufacturing processes more flexible, smarter and future-proof. Those who embrace this can secure long-term competitive advantages and respond better to new challenges.

Challenges: Where companies fail in the digital transformation and how you can do better

Digitalization in manufacturing brings many advantages, but also some challenges. Companies not only have to reckon with technological and financial hurdles, but also take organizational and security-related issues into account. Those who recognize and address these challenges early on can avoid typical mistakes and successfully shape the path to the digital future.

One major problem is the high initial investment. The introduction of new automation technologies, sensor technology and data-driven processes requires high financial resources. The total costs, especially for the integration of existing systems or necessary IT infrastructure, are often underestimated. Added to this is the lack of uniform standards, which makes it difficult to integrate different machines and software solutions. Without a well-thought-out digitalization strategy, the changeover can be expensive and inefficient.

IT security and data protection are also important issues. The increasing networking of machines, cloud services and IoT systems also increases the risk of cyberattacks. Robust security concepts with preventive IT security measures and employee training in the secure use of digital systems are essential. This is the only way to protect sensitive production data and ensure smooth operations at the same time.

The acceptance of employees should also not be forgotten. New technologies require new knowledge and not everyone is immediately enthusiastic about change. However, if employees understand why change is important, resistance can be reduced through further training and open communication.

Digital manufacturing is not just about technology, but also about strategy, security and people. Those who make the right decisions, keep safety in mind and involve their employees will remain competitive in the future.

Human vs. machine? Why the human factor remains crucial in digitalization

When talking about digitalization in manufacturing, the question often arises as to whether machines will take over our work at some point. Sure, automation through intelligent systems makes many things faster and more efficient, but they still need people. Machines don’t run on their own: they need to be monitored and adapted. This requires well-trained specialists who are able to solve complex problems and drive innovation.

Ultimately, it is the employees, with their technical expertise and creativity, who make the true added value of digital technologies possible in the first place. People remain irreplaceable when it comes to developing innovative solutions and finding the right strategy for digital change. That’s why it’s so important that companies to continuously train and educate their teams so that everyone understands how to make the best use of new technologies.

Digital manufacturing is not about replacing people with machines, but about bringing the two together. Machines ensure greater efficiency, while people use their experience and ingenuity to steer and further develop the digital transformation.

Conclusion: Digital progress won’t wait – set the course now

The digital transformation has long since reached the manufacturing industry. According to a PWC study, 64% of companies are still at the beginning of their digitalization efforts, but the digital pioneers are already investing 45% of their IT budget in transformation projects.² Automation, the use of data and predictive maintenance ensure that processes become leaner and quality increases. With concepts such as the smart factory and the principles of Industry 4.0, companies can shorten their production times and use resources more efficiently.

Of course, this progress also brings challenges – such as investing in modern IT structures and reliable security solutions. But more importantly, employees need to be involved. Their expertise and commitment are crucial if new technologies are to develop their full potential.

Those who invest in digital progress today are laying the foundations for sustainable and future-proof production. This is also confirmed by figures from the German Federal Ministry for Economic Affairs and Climate Protection: 91% of companies see Industry 4.0 as a prerequisite for maintaining the competitiveness of German industry.¹ Change will not wait – now is the time to take action.
