Alumina-Zirconia composite ceramic has some excellent properties as wear resistance and fracture toughness. However, this material is hard to grind with high efficiency or high grinding ratio. In this paper, experiments are carried out to establish the total high efficiently grinding including truing and dressing conditions. The main results obtained are as follows: (1) It's easy to true a grinding wheel using proposed method, but cutting edges are flatten. Therefore, high normal grinding force happened and increased rapidly with an increase of accumulative removal volume of ceramic. (2) Dressing process is necessary to remove the flatten cutting edges and bonds. And, it is clear that the optimum dressing condition exists. (3) Grinding at higher stroke speed exhibits lower grinding force and higher grinding ratio.
