Lapping is the process of using a grinding compound of free grit and oil to create very precise surfaces of high finish. Flat lapping machines are used to make small flat surfaced parts (figure 1).

Polishing and buffing are also methods of grinding. The buffing compound (grit) is applied to buffing wheels (figure 2) that are mounted on special buffing grinders (figure 3)
