Abstract：In order to the influence of the multi-pore structure of the ceramic hollow ball super hard abrasive on the grindingtemperature，the structure and grinding model of ceramic hollow ball composite super hard abrasive were investigated. The analysis of themechanism of the effects of the multi-pore structure on depth of cut and flow of cooling fluid was made in theory. On the temperature，theeffects of depth of cut and flow of cooling fluid were tested，varied trends of grinding temperature according to different depth of cut andflow of cooling fluid were analyzed. The experimental results show that the grinding wheel with hollow ball super hard abrasive has more
holes in the working layer，it can carry more cooling fluid into the grinding area for heat exchanges and its grinding temperature is lowerthan normal super hard abrasives grinding wheel and thus reducing the grinding temperature can be.
