What is Cylindrical Grinding - Steps in Cylindrical Grinding

Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece.

The oldest machining process - at the beginning of “Stone Era

GRINDING MACHINES (GRINDERS) Two standard types of shapes: Cylindrical and Flat The form of the work gives the type of the grinder - Special grinders for tool grinding (other type of shapes ) - Grinders –heavy and rigid machines, with precise controls and special protection of moving parts.
