The authors developed a SiC whisker grinding wheel with its whiskers aligned normally to the grinding surface, and have studied the grinding characteristics of this wheel. Using this new type of grinding wheel, a surface finish of 16 nm Ry (l. 5nm Ra) roughness was successfully produced in hardened die steel (SKDll, HRC60).In this work, a few honing stones of aligned whiskers, alumina and CBN were prepared, and its honing performances were investigated. Moreover, the effectiveness of the addition of vibration in honing process was examined. The honing efficiency were remarkably improved by the addition of vibration. The following conclusions were obtained.1) SiC whisker stone decreases the honing efficiency than alumina and CBN but a better surface finish is obtained.2) With regard' to the cross-hatch angle, a larger angle improves surface finish.3) With regard to the addition of vibration, the most honing efficiency is obtained when adding the vibration of 800 Hz.

研制了一种晶须垂直于磨削表面的SiC晶须砂轮，并对其磨削特性进行了研究。使用这种新型砂轮，表面光洁度为16 nm Ry（l.本文制备了几种定向晶须、氧化铝和CBN珩磨油石，并对其珩磨性能进行了研究。此外，在珩磨过程中添加振动的有效性进行了检查。通过加振，珩磨效率得到了显著提高。结果表明：1）SiC晶须的加入降低了珩磨效率，但获得了较好的表面光洁度; 2）在网纹角度方面，较大的网纹角度提高了表面光洁度; 3）在振动频率方面，当振动频率为800 Hz时，珩磨效率最高。
