Abstract: A process for lapping a surface and providing a very smooth surface in short periods of time comprises:a) providing a work piece to be lapped, having at least one surface to be lapped,b) providing a rotating platen havingi) a back surface andii) a flat surface which can be adjusted to a position parallel to said at least one surface of said work piece,c) providing a sheet of abrasive material having an abrasive face and a back side, said back side being on said flat surface of said platen with the abrasive face of said sheet facing said at least one surface to be lapped,d) securing said sheet of abrasive material to said flat surface of said platen,e) rotating said platen at a rotational speed of at least 500 revolutions per minute, and a surface speed at an outside edge of said sheet of abrasive material of at least 1500 surface feet per minute, andf) contacting said abrasive face and said at least one surface of said workpiece to be lapped.
