Vollmer says its new VGrind Infinity Linear tool grinding machine can precisely, quickly and energy-efficiently machine precision tools with diameters from 0.2 to 200 mm from different materials such as carbide, HSS, PcBN or ceramic. Automation and digital capabilities enable unmanned operation around the clock, from small batch sizes and special solutions to series production.

The foundation for precise sharpening processes consists of two vertically configured grinding spindles, which enable efficient multi-level machining and thus resolve issues associated with fixed and floating bearings commonly found in competitor machines. Furthermore, the grinding wheel set at the pivot point of the C axis and the wear-free linear induction motors on the X, Y, and Z axes ensure a lifetime of accuracy and stability.

Thanks to the configurable spindles, tool manufacturers can customise both the speed and power for the tool and cutting material. The optimised spindle transmission ratio guarantees a constant torque, which is delivered by the compact, powerful and energy-efficient motor.

The rigidity of the VGrind Infinity Linear and the intelligent cooling concept, which ensures thermal stability with plate heat exchangers, deliver the required tool precision. If necessary, the machine also runs through a defined warm-up program for thermal stability at the start of a shift. As soon as all monitored operating parameters are within the target range, scheduled production starts automatically.

In terms of tool dimensions, the VGrind Infinity Linear is capable of machining micro tools with diameters from 0.2 mm up to large drills and milling cutters with diameters of 200 mm – all with tool lengths of up to 360 mm.
