① simple equipment, less demanding accuracy.
② reliable processing quality. Ra value obtained very high precision and very low. But generally does not improve the positional accuracy of the machined surface and other surfaces.
③ process a variety of steel, hardened steel, cast iron, copper and aluminum and its alloys, tungsten carbide, ceramic, glass and some plastic products.
④ grinding widely used in single and small batch production and processing of various high-precision surface, and can be used in a large number of mass production.
