As a finishing process, lapping plays a major role in establishing the final dimensional and surface

characteristics for many industrial parts. Lapping operation is used for many work materials

including glass, ceramic, plastic, metals and their alloys, sintered materials, stellite, ferrite, copper,

cast iron, steel etc.

Lapping is primarily considered to be a three-body abrasive mechanism due to the fact that it uses free abrasive grains that can roll or slide between the work piece surface and the lapping plate, although some grains become embedded in the lap leading to two-body abrasion. Lapping is a loose abrasive machining process that combines abrasive particles within an oil or aqueous medium depending on the material being finished. Fine abrasive is applied, continuously or at specific intervals, to a work surface to form an abrasive film between the lapping plate and the parts to be lapped. 

Each abrasive grain used for lapping has sharp irregular shapes and when a relative motion is induced and pressure applied, the sharp edges of the grains are forced into the work piece material. Each loose abrasive particle acts as a microscopic cutting tool that either makes an indentation or causes the material to cut away very small particles. Even though the abrasive grains are irregular in size and shape, they are used in large quantities and thus a cutting action takes place continuously over the entire surface in contact.
