A magnetic-electrolytic-abrasive polishing (MEAP) system was newly developed and the finishing characteristics of a Ct-coated roller were analyzed. The paper describes the operational principle of the MEAP system and the magnetic field effect on the MEAP process using experimental results. The finishing characteristics and optimal finishing condition for the Cr-coated roller were experimented upon and analyzed. (C) 1997 Elsevier Science Ltd.
