Surface finishing processes

Abstract

Grinding is an operation performed by a rotating abrasive wheel, which removes metal from the surface of an object. It is usually a finishing operation which gives a good surface finish and high dimensional accuracy to workpieces which have already been machined by other methods. Very little metal is removed in this operation. Grinding is also used to machine materials which are too hard to be machined by other methods.The different types of grinding processes are:

(1) External cylindrical grinding, including centreless grinding (2) Internal cylindrical grinding (3) Surface grinding (4) Form grinding.
