This is a surface finishing process used on flat or cylindrical surfaces but often employed externally. Here abrading of a surface by the method of lay is carried out. Lap is nothing but a material made of a material softer than the material to be lapped. Lap is charged with the fine abrasive particles. The lap and the surface to be finished are rubbed together using fine abrasive particles and these particles become embedded in the softer lap. Lapping is employed to ensure geometrical truth of the surface, to correct shape imperfections and to obtain dimensional accuracy.
