8 Principles of Centerless Grinding Metal Cutting

2016-12-8 A larger abrasive grinding wheel; The beauty of centerless grinding is that the workpiece is held in place by the pressure of the rotating wheels. No fixturing is required, so the setup is simple and turnaround times are fast. And because the workpiece is rigidly supported, there is no deflection during the grinding operation.
