ABSTRACT:
Lapping or polishing at high speeds with fine abrasive particles offer significant advantages in the speed of lapping, savings of time in lapping, and smoothness in the finished articles. An improved lapping system comprises a lapper platen system comprising: a) a frame (e.g., having a total weight of at least 200 kg) supporting a work piece holder b) a rotatable platen having an abrasive surface comprising an abrasive sheet secured to said platen, said platen being capable of providing surface feet per minute speeds on in outer edge of at least about 1,500 surface feet per minute; and c) a work piece holder which is movable on said frame.
