Lap/polish plates revolve at slow speed. The conditioning rings held in position on the machine plate also rotates freely. Lapping Machine Parts are kept free inside conditioning rings with the surface to be lapped facing the machine plate. The sharp abrasive particles which are continuously fed on the machine plate gets charged in the plate and cuts the material from the surface of the work piece transferring the flatness of the plate on to the work piece surface. The surface finish produced on the parts depends upon abrasive particle size used in the process.
