In the reseach, the ductile-mode ultra-smoothness grinding conditions of fine ceramics such as silicon carbide, silicon nitride and alumina-titanumu carbide ceramics with the coarse #140-mesh grain size diamond wheel are investigated. The main conclusions obtained are followed :(1) First of all the possibility of the ducile-mode ultra-smoothness grinding with coarse #140-mesh grain size diamond wheel examined for various kinds of ceramics. The smoother surface roughness than 30nm (P-V) is obtained for silicon carbide, silicon nitride and aluminatitanium carbide ceramics(2) The suitable ultra-smoothness grinding conditions depends on the kind of fine ceramic. It is considered that the table speed, wheel speed, and the wheel specification, specially grain size and concentration of wheel, which relates the wear area and distribution of cutting edge on the wheel surface. The quantitative research on the ultra-smoothness grinding for the various kinds of fine ceramic is the subject in next step.(3) To clear the relationship between the wheel surface conditions and the ultra-smoothness grinding conditions, the automatic image processing system for grinding wheel surface is developed.

研究了用140目粗粒度金刚石砂轮对碳化硅、氮化硅、铝钛碳化物等精细陶瓷进行延性超光滑磨削的工艺条件。得到的主要结论如下：（1）首先考察了#140目粗粒度金刚石砂轮对各种陶瓷进行延性模式超光滑磨削的可能性。碳化硅、氮化硅和碳化铝钛陶瓷的表面粗糙度均小于30 nm（P-V）。（2）超细陶瓷的超光滑磨削条件取决于超细陶瓷的种类。研究认为工作台转速、砂轮转速、砂轮规格，特别是砂轮的晶粒度和浓度，与砂轮表面的磨损面积和分布有关。各种精细陶瓷超光滑磨削的定量化研究是下一步的课题。(3)为明确砂轮表面状态与超光滑磨削条件之间的关系，开发了砂轮表面自动图像处理系统。
