英文摘要：

This paper presents the research of grinding temperature caused by machining sintered Nd-Fe-B permanent magnetic material through the way that was controlled-force radial ultrasonic vibration aided face grinding. The grinding force and speed in the process of the grinding were mainly analyzed; The theoretial calculation and experimental validation of the grinding surface temperature were completed, and it was founded that the temperature of controlled-force radial ultrasonic vibration aided face grinding was higher than that of controlled-force face grinding, and the main reasons were pointed out in this paper. The satisfying machining properties can be obtained and workpiece burn can be controlled through the research of grinding temperature, then the composite machining technique may be used.
