At the EMO Milano exhibition in October, Vollmer delivered the public premiere of its VGrind 360S grinding machine for the complete machining of carbide tools. This new five-axis CNC grinding machine can produce carbide tools with a diameter up to 25.4 mm and, depending on machine kinematics and the equipping of grinding wheel packages, it can even be used for tools up to 150 mm diameter. The VGrind 360S incorporates wear-free linear induction motors on the X, Y and Z axes to lower maintenance costs for the machine, while contributing to higher surface quality for the tool.

The tried-and-tested vertical double-spindle concept from Vollmer now features an oriented spindle stop for the first time. Also known as spindle indexing, this function always stops the spindle at a specific position, resulting in a reduction of axial run-out errors and concentricity issues, while offsetting wear in the HSK holding system. Another new feature is a heat plate exchanger to efficiently cool the motors and spindles, which in turn leads to increased thermal stability.

Simple and intuitive operation is at the core of the VGrind 360S and, for customers to fully exploit its potential, Vollmer has created an ergonomic platform whereby users can operate the control panel comfortably while having full visibility of the work envelope. Operation via the keyboard or touchscreen allows for precise machining of the tool, and the multi-function hand wheel ensures even more flexibility as operators can position it freely on the enclosure. This design allows the setting of a required axis without using the control panel.

The VGrind 360S incorporates Vollmer’s established operating concept and can be used unmanned around the clock thanks to automation features such as a pallet magazine, free-arm robot or chain magazine.
