INTRODUCTION TO GRINDING PROCESS • • • It is the only economical method of cutting hard material like hardened steel. It produces very smooth surface, suitable for bearing surface. Surface pressure is minimum in grinding. It is suitable for light work,which will spring away from the cutting tool in the other machining processes. 3.

Mechanical properties Hard cutting and grinding processes have to create the final geometry and surface topography of the workpiece, to ensure its functionality. To achieve more wear resistance, the workpieces are hardened before the finish-machining. Depending on the heat treatment, the workpieces are through hardened or surface hardened.
