Sintered Nd-Fe-B magnet is the third generation rare earth permanent magnetic material. In this paper, contrasted with traditional grinding, the experiment of radial ultrasonic vibration aided grinding of sintered Nd-Fe-B permanent magnetic material was conducted. The effect on normal grinding force of grinding parameters was analyzed respectively in the two grinding processes. Experimental results indicate, the process of radial ultrasonic vibration aided grinding is especially suitable for shape machining of sintered Nd-Fe-B permanent magnet. The radial ultrasonic vibration improved the stability of grinding, and in the precondition of high machining efficiency, avoided edge collapse in a certain extent, assured the integrality of machining surface.
