近十年来,立方氮化硼磨具在工业的各个部门实际上早已得到广泛的应用。立方氮化硼的硬度仅次于金刚石,而其耐热性和化学惰性却高得多,故在磨削和刃磨高速钢(特别是含钨量低的高速钢)刀具时效率更高。
The past decade, cubic boron nitride abrasive in various sectors of industry has long been widely used. Cubic boron nitride is second only to diamond and its heat resistance and chemical inertness are much higher, so it is more efficient when grinding and sharpening high speed steels (especially those with lower tungsten content).
