ABSTRACT:
A magnetic barrel finishing machine causes multiple different flows or motions of the abrasive media and workpieces by varying magnetic fields, thereby freeing the workpieces from the abrasive media and subjecting the workpieces to finishing action by the abrasive media. The machine includes a rotator made of magnetic material and a plurality of permanent magnets rigidly mounted on the rotator. A container is located above the rotator with a small gap therebetween, and contains workpieces to be finished and an abrasive medium of magnetic material, or workpieces to be finished and an abrasive medium including a magnetic material. The permanent magnets are arranged irregularly in such a way that they provide magnetic lines of force acting in the circumferential direction as well as the radial direction of the rotator.
