GrindingHub 2026: Vollmer increases efficiency in tool machining with automation and AI 12.03.2026

At GrindingHub 2026, VOLLMER WERKE Maschinenfabrik GmbH will present itself as a competent partner for tool manufacturing. In Hall 7, Stand D71, the Biberach-based sharpening specialist will showcase its comprehensive portfolio of grinding, erosion and laser machines for the efficient machining of ultra-hard cutting materials such as PCD, CVD diamond, PcBN and carbide. The focus will be on automated production concepts, digital solutions and the targeted use of artificial intelligence (AI).

Hybrid machine concept as the key to efficiency

With increasing demands for precision and cost-effectiveness, Vollmer is specifically focusing on the hybrid machine concept of the VHybrid 260, which combines mechanical grinding processes with contactless EDM technology and digital solutions in a single machine. The VHybrid 260 not only represents the combination of several sharpening technologies but also forms the basis for fully digitalised and automated production processes. A central element is the Vpulse EDM generator, which enables the highly precise production of even the smallest micro-tools with diameters of 0.2 millimetres. During the erosion process, surface finishes of up to 0.05 μm Ra can be achieved. In addition, cutting edge radii of up to 1.5 μm can be produced. This can eliminate the need for subsequent grinding of functional surfaces, avoiding tolerance risks caused by re-clamping as well as additional process-intensive steps, thereby significantly reducing overall production costs.

At GrindingHub 2026, Vollmer will present its portfolio of grinding, erosion and laser machines that allow customers to machine ultra-hard cutting materials such as carbide, PCD, CVD diamond and PcBN. With a view to greater efficiency, hybrid machines in particular make it possible to sharpen tools faster and with higher quality. This can be seen, for example, in full-head PCD tools with complex geometries: within a single clamping operation, contours can be ground in carbide while the cutting edges in the PCD head are eroded. This approach not only shortens main and auxiliary processing times but also ensures a virtually seamless transition between the PCD head and the carbide blank – without irregularities or steps. The VHybrid 260 demonstrates particular strengths in cylindrical EDM. This contactless, highly precise process enables economical machining. Micro-tools in particular benefit from this, where dimensional accuracy, surface quality and reproducible processes are decisive. The combination of cylindrical grinding and cylindrical EDM enables the production of extremely small tool diameters with high precision, process reliability and efficiency – within a continuous, automated process chain.

Process for producing defined edge chamfers

For drilling tools, a rounded edge chamfer proves advantageous for several reasons. Sharply eroded cutting edges can lead to problems in various application scenarios – particularly in the area of PCD drilling tools. A cutting edge without a rounded chamfer can result in unstable cutting, increased wear, reduced tool reliability and deterioration in workpiece quality.

A rounded chamfer not only creates a defined cutting edge contour with reduced chipping but also improves the stability of the cutting edge as well as the surface structure and roughness in the cutting edge area. This leads to longer tool life, increased process reliability and improved workpiece quality. By integrating the chamfering process into the VHybrid 260, users are able to perform complete machining on a single machine. Geometry machining and the production of the rounded chamfer – whether eroded or ground – can be carried out in one clamping operation. Through the integration of LaserCheck, a closed-loop process can also be implemented, eliminating the need for manual adjustments during machining.

Automation and digitalisation for 24/7 production

Regardless of the sharpening technology used, all Vollmer machines are consistently designed for automated 24/7 production. Central robot systems handle loading via carts, pallet loaders or chain magazines and monitor the fully automated complete machining process. A newly developed ND gripper with an automatically adjustable gripping diameter significantly expands possibilities in tool handling. Its flexible adaptation to a wide range of tool types increases both process reliability and versatility in operation. At the same time, the innovative solution helps noticeably increase efficiency in automated loading. 
Machine and production data are recorded, analysed and managed via a central IoT platform. The web-based VPortal serves as a central information and service platform, offering users a transparent overview of documentation and service information. In addition, the Smart Hub intelligently consolidates production and
machine data and prepares them for further analysis. AI-supported algorithms and an intelligent chatbot assist users in analysing documentation and historical data, providing relevant information on machine utilisation, production volumes and scrap rates.

AI and digitalisation as an opportunity for SMEs

“Especially for small and medium-sized enterprises, the combination of hybrid machine technology, digitalisation and AI offers major opportunities,” says Tobias Trautmann, Managing Director of the Vollmer Group. “Processes can be made more transparent, downtime reduced and resources used more efficiently. With the VHybrid 260, we are creating a platform where different sharpening technologies, digital solutions and AI applications work seamlessly together to measurably optimise production processes.”

Machine portfolio live at GrindingHub

At GrindingHub 2026, Vollmer Werke will also present additional solutions from its current machine programme. These include the VLaser 370 in an automated version as well as the VGrind Infinity linear. The exhibition appearance will be rounded off by the models CS 860 and CP 650 as well as the KSC560-B from the subsidiary Loroch.
