The grindability of fine-ceramics is the most important information in order to determine the optimum grinding conditions and dressing intervals. This study proposed the method of grindability evaluation of fine-ceramics by using removal rate in constant pressure grinding. In this paper, constant pressure grinding of four kinds of alumina in which particle diameter differs was performed. And, the influence of particle diameter on removal rate was examined. As a result, it found that the removal rate increases by the 0.5th power of particle diameter based on the Griffith theory. Then, the removal rate in consideration of particle diameter was formulated based on this experimental result. The calculated removal rate was well corresponding to the removal rate obtained by experiments. From these results, the possibility of evaluating the grindability from both mechanical properties of fine-ceramics and particle diameter was found.
