CHAPTER 1- INTRODUCTION TO GRINDING

operation are called active grains. In peripheral grinding , each active grain remove a short chip of gradually increasing thickness in a way that is similar to the action of a tooth on a slab milling cutter. Because of irregular shape of the grains, however, there is considerable interface or plowing action, between each active grains and the new work surface. This plowing action

8 Principles of Centerless Grinding - Metal Cutting ...

2016-12-08  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.
