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.

History of Lapping Machine

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

Stone age man (fig-1) used the process of lapping in preparing their tool and implements to the extent that they drilled holes in a work piece by rotating sticks on it sand strewn surface.
