Abstract: A vibrational magnetic polishing machine comprises a machine frame on which a workpiece container, an action device and a rotary alternating magnetic field generator are mounted such that the workpiece container is vibrated by the action device, thereby causing the workpiece and the polishing media to jump in the container. The polishing media arc induced by the alternating magnetic field to jump so as to smooth the surface of the workpiece.

Abstract: A magnetic polishing machine comprises a polishing tub and an alternating magnetic field generator for producing a magnetic field effect to induce a number of magnetic media to travel at a high speed to polish by rubbing a workpiece contained in the polishing tub. The magnetic polishing machine further comprises a built-in separation tub and a homomagnetic field generator for generating a unidirectional magnetic field effect to separate the cohered magnetic media from the workpiece which is transferred from the polishing tub to the separation tub upon completion of the polishing process.
