ABSTRACT:
The present invention provides a method for processing such as deburring, polishing and washing of surfaces of slits of a workpiece, having slits with narrow width from outer surface toward inside, with high accuracy and high efficiency. Magnetic abrasive material is retained in a magnetic field formed between magnetic poles 3 and 4, and magnetic brushes 5 are formed. A workpiece 1 made of non-magnetic material and having slits 1f with narrow width is placed in said magnetic brushes 5, and by relatively vibrating said magnetic poles and said workpiece, surfaces of the slits are processed. It is more effective to tilt the slit surface with respect to the magnetic field after the slit surface is arranged in parallel to the magnetic field.
