초록

This study has focused on the application of magnetic assisted polishing for ELID ground surface of aluminum oxide ceramics. Aluminum oxide ceramics has been widely used as advanced materials for electric, optic, mechanic, chemical usage and so on. In this study, ELID grinding and magnetic assisted polishing technology was adopted for high-effective manufacturing and high quality surface of ceramic parts. The characteristic of MAP machining have been evaluated by the value of surface roughness and surface profile before and after magnetic assisted polishing. As the results of experiments, the surface roughness after magnetic assisted polishing has shown a significant improvement and the surface roughness was more improved when the feed rate of tool became slow.
