Tool Grind Workholding System Limits Runout - Production Machining

The two-component system consistently limits radial and axial runout to less than 0.0001 inch (3 microns) for tools 2 inches (50 mm) from the face of the collet. Typical tool grinder runout is about 0.0002 inch. Suitable for both manual and automated tool loading, it can be used for the production grinding of 3- to 13-mm diameter tools.
