Precision Metal Grinding - Metal Cutting Corporation

In fact, grinding is often considered a subset of cutting, and vice versa, since each grain of abrasive on a grinding wheel acts like a microscopic, sharp cutting edge that shears a tiny chip from a part surface. In general, precision metal grinding processes are used to remove small amounts of material in order to achieve a particular finish ...
