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.

在研究中，研究了细陶瓷的延性超平滑度磨削条件，例如碳化硅，硝酸硅和氧化铝 - 丁香碳化物陶瓷，具有粗糙的＃140-MESH谷物尺寸钻石轮。遵循获得的主要结论：（1）首先，首先检查了对各种陶瓷的粗＃140英寸晶粒尺寸钻石车轮进行粗略的磨碎。对于碳化硅，氮化硅和碳化铝碳化物陶瓷（2），获得了比30nm（P-V）的表面粗糙度更平滑（P-V）（2），合适的超平滑度磨削条件取决于那种优质陶瓷。据认为，台式速度，车轮速度和车轮规格，特别是晶粒尺寸和车轮浓度，这将磨损面积和车轮表面上的尖端分布相关。下一步是对各种精美陶瓷的超平滑度研磨的定量研究。（3）为了清除车轮表面条件与超平滑度研磨条件之间的关系，开发了用于磨轮表面的自动图像处理系统。
