This paper describes a new finishing process (magnetic abrasive finishing process) in which a free from surface is finished in magnetic field using magnetic abrasives of 80 μm in mean diameter composed of both iron and alumina particles. From the experimental results, it is found that the spherical surfaces (convex surface and concave surface) of ferro-magnetic substance are finished very easily in a short time and its machining accuracy is high. On the other hand, the finishing performance in the case of non-ferro-magnetic substances is restricted due to the work thickness. Next, the finishing possibility for a free form surface is confirmed by modelled experiments in which plane and cylindrical surfaces are machined by applying a NC controlled machine tool.
