This paper describes a new finishing process using magnetic abrasives in which the finishing pressure is generated by a magnetic field. The process principle and the finishing characteristics
are described. Specifically, the effect of the magnetic abrasive particle size on stock removal and
surface finish is investigated for cylindrical finishing. Based on the results, diamond coated magnetic
abrasives were newly made to finish Si3N4 fine ceramic bars (12mm in dia.) and its finishing performances were clarified. The surface roughness of 0.45 µm Ra before finishing was improved to 0.04 µmRa. It was also clarified that the precision edge finishing of about 0.01 mm in radius was performed easily by this process.
