在美国,用立方氮化硼砂轮磨削淬硬工具钢、合金铸铁和镍基、钴基高温合金零件已有15年以上的历史。用立方氮化硼砂轮磨削可提高生产率,精密控制磨削尺寸精度和表面光洁度;此外,更重要的是可改善磨削零件的疲劳强度,提高其寿命和可靠性。 In the United States, with cubic boron nitride grinding wheel hardened tool steel, alloy cast iron and nickel-based, cobalt-based superalloy parts for more than 15 years of history. Grinding with CBN grinding wheels increases productivity with precise control of the grinding dimensional accuracy and surface finish; more importantly, it improves the fatigue strength of the grinding parts and increases their life and reliability.
