Abstract：The research situation of new magnetic abrasive particle,improvement on magnetic abrasive finishing device,electrochemical magnetic abrasive finishing( EMAP),and ultrasonic assisted magnetic abrasive finishing( UMAF) are described,and the finishing mechanism of EMAF and UMAF are expounded. Pointed out that the research and development of unbonded magnetic abrasive and compound magnetic abrasive finishing are the main method to improve the performance of magnetic abrasive finishing. The problem of this technology that need to pay particular attention to is discussed,based on the review of the magnetic abrasive finishing.
