摘　　要：对高强度共晶复合TiC-TiB_2陶瓷进行了不同参数下的普通加工和超声旋转加工的对比试验,研究分析了超声旋转加工中不同加工工艺参数对加工工件表面质量的影响。实验结果表明:在同样的加工工艺参数下,超声旋转加工比普通加工的表面粗糙度值小,能获得更好的加工表面。在超声振动加工中由于砂轮做高频振动,不易堵塞,有利于使用细粒度砂轮。The contrast experiments of grinding TiC-TB2 between rotary ultrasonic machining- （RUM） and common machining were carried out in this paper. The influence of RUM on the surface quality of TiC-TB2 ceramics was analysed, different processing parameters that influence the surface roughness were studied. The result of testing showed that, with the same processing parameters, the RUM surface roughness were smaller than common grinding, and we can obtain a better surface. Besides, the grinding wheel works at high frequency vibration so that it is not easily loaded, which permits fine grint wheel to be used in RUM.
