The research is done for the aims of building the high removal ultra-smoothness grinding technique of fine ceramics with coarse grain size diamond wheel. In the present research, first of all, by using silicon carbide ceramic, the mechanism of ultra-smoothness grinding with coarse grain diamond wheel is investigated experimentally and theoretically. The experiments are carried out with NC surface grinder. The bond, concentration and grain size of diamond wheel used are metal, 100 and #140, respectively. On the basis of the result, the existing of limiting smoothness, which can attain in traverse grinding is discussed theoretically and presented experimentally. Furthermore the newly devised ultra-smoothness grinding method is proposed and ascertained to be useful for finishing to near the ultra-smoothness surface.The main conclusions obtained using the new ultra-smoothness grinding method are as follows;(1) The surface roughness of silicon carbide ceramic formed by the ultra-smoothness grinding method using #140 diamond wheel is found to attain below 10nm(Ry) or 2nm(Ra).(2) The surface roughness of silicon nitride ceramic and alumina-titanium carbide ceramic is somewhat worse than silicon carbide ceramic though it attains to near the ultra-smoothness surface too.(3) In the cemented carbide without fine ceramics, the surface roughness attains below 30nm(Ry) or 4nm(Ra).

这项研究的目的是为了建立具有粗谷物尺寸钻石轮的高陶瓷的高移除超平滑度磨削技术。在本研究中，首先，通过使用碳化硅陶瓷，通过实验和理论上研究了用粗粒钻石轮磨的超平滑度的机理。实验是用NC表面研磨机进行的。所用钻石轮的键，浓度和晶粒尺寸分别为100和＃140。在结果的基础上，在理论上和实验中讨论了可以在遍历磨削中获得的限制平滑度。此外，提出并确定新设计的超平滑度磨削方法可用于完成在超平滑度表面附近。使用新的Ultra-Smoothness Grinding方法获得的主要结论如下；（1）使用硅含量为140的液体铜制的液化液的表面； 10nm（ry）或2nm（ra）。（2）硝酸硅陶瓷和碳化木陶瓷的表面粗糙度比碳化硅陶瓷较差一些，尽管它在超平滑的表面附近也达到了carbide carbide carbide carbide carbide的表面。
