Lapping Process

Lapping is the process of rubbing two surfaces together with a lapping medium (Lapping fluid and Lapping Grit) between them.

Lapping is a low pressure abrading process which is employed as a precision finishing operation tooling to achieve high dimensional accuracy, improve geometrical accuracy, fine surface finish and ensure close fit between mating parts.
