In this paper a new method of lapping as a way of automatically finishing the "die" is proposed, which utilizes a permanent rubber magnet to apply to the final finishing process of the "die" and is one of magnetic field assisted lapping. This method does not require any expensive and complicated apparatus compared with other magnetic field assisted lapping. In this paper two types of rubber magnet stronger and weaker magnetic forces were used, and hardened steel S55C as a specimen, and the mixture of # 400 and # 800 of WA abrasives and city water as a lapping fluid respectively were employed. Fundamental analyses of the lapping operations were made. It became evident that the lapping is also possible in this method as well as in conventional lapping.}, pages = {63--67}, title = {Fundamental Study on Magnetic Field Assisted Lapping with Rubber Magnet}, volume = {32}, year = {1990} }
