Surface grinding Wikipedia

Surface grinding Wikipedia

Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.This is machine also used in many industries to surface grinding.
