Vollmer showcases hybrid tool manufacturing at GrindingHub 2026

At GrindingHub 2026 (May 5–8, Stuttgart), VOLLMER WERKE Maschinenfabrik GmbH will present its technologies for tool manufacturing in Hall 7, Stand D71. The focus is on solutions for machining ultra-hard cutting materials such as PCD, CVD diamond, PcBN and carbide, complemented by concepts for automation, digitalization and the use of artificial intelligence in production.

Hybrid machine concept for integrated processes
A central element of the exhibition is the VHybrid 260, a hybrid machine concept combining grinding and electrical discharge machining within a single system. The integration of mechanical and non-contact processes enables continuous production workflows without re-clamping, reducing tolerance risks and eliminating additional processing steps.

A key component is the Vpulse EDM generator, which enables high-precision manufacturing of micro tools with diameters down to 0.2 millimeters. Surface finishes of up to 0.05 μm Ra can be achieved during EDM, while cutting edge radii down to 1.5 μm are possible. This level of precision can reduce the need for subsequent grinding operations and lower overall production costs.

The advantages of the hybrid approach are particularly evident in complex tool geometries, such as full-head PCD tools. In a single setup, contours can be ground in carbide while cutting edges in the PCD section are eroded. This reduces main and auxiliary processing times and ensures seamless transitions between different materials.

Precision machining and defined cutting edges
In cylindrical EDM applications, the VHybrid 260 enables precise and economically efficient machining. This is particularly relevant for micro tools, where dimensional accuracy, surface quality and process stability are critical. The combination of cylindrical grinding and EDM allows small tool diameters to be produced within a fully automated process chain.

For drilling tools, the creation of a defined edge chamfer improves cutting stability, wear behavior and workpiece quality. Integrating this process into a single machine enables complete machining without additional clamping steps. The use of LaserCheck systems further supports a closed-loop process, allowing automated measurement and correction during machining.

Automation and digital infrastructure
Vollmer’s machines are designed for automated 24/7 production. Robotic systems handle loading and manage the complete machining process, while flexible gripper systems enable adaptation to different tool types.

At the same time, machine and production data are captured and analyzed via a central IoT infrastructure. The web-based VPortal provides access to operational, service and documentation data, while the Smart Hub processes and structures data for further analysis. AI-supported functions assist in evaluating production metrics and contribute to optimizing machine utilization and process stability.

Machine portfolio and applications
In addition to the VHybrid 260, Vollmer presents further systems including the VLaser 370 in an automated configuration and the VGrind Infinity linear. The portfolio is complemented by the CS 860 and CP 650 models, as well as the KSC560-B from its subsidiary Loroch.

The showcased solutions address applications in tool manufacturing requiring high precision, reproducible processes and efficient production workflows. The combination of hybrid machining, automation and digital integration provides a foundation for scalable and cost-efficient manufacturing.
