一、引言立方氮化硼砂轮(简称 CBN 砂轮)是当前高效磨削各种难加工材料的理想砂轮,把几种切削工具材料的耐磨性进行比较可得出:若硬质合金为1,陶瓷为10～30,立方氮化硼则为50,显而易见,立方氮化硼具有较高的耐磨性,同时其导热性和耐热冲击性也好,生产率高,立方氮化硼的发展和普及是80年代和90年代的技术发展的一个中心课题,权威人士指出:CBN 的出
I. Introduction CBN grinding wheel (referred to as CBN grinding wheel) is the current efficient grinding all kinds of difficult to machine the ideal grinding wheel material, several cutting tool wear resistance can be drawn: If the carbide is 1, Ceramic 10 to 30, cubic boron nitride is 50, it is clear that cubic boron nitride has high wear resistance, thermal conductivity and thermal shock resistance is also good, high productivity, the development of cubic boron nitride and Popularization is a central topic of technological development in the 1980s and 1990s. Authorities pointed out: CBN’s
