This paper describes the process principle and a few finishing characteristics of the magneticabrasive finishing in which susceptive abrasives magnetically (magnetic-abrasives so called) made of iron and alumina particles are used. It is found experimentally by a model test that the magnetic-abrasive pressure is introduced by magnetic field strength and its measured value reaches at the conventional lapping pressure one. These experimental results are discussed analytically. The experiments showed that a cylindrical workpiece is finished smoothly in a short machining time from the unmachined surface roughness value of about 1.5 μmR_max to the machined value of submicron. Magnetic-abrasive finishing process reported in this paper will be used in practice.
