1研究背景在机械加工中,正确选择和应用刀具材料至关重要。超硬刀具材料有两种:立方氮化硼(CBN)和金刚石。金刚石硬度最高,可达10000HV,CBN的硬度仅次于金刚石。金刚石刀具仅适合加工非铁金属材料和非金属材料;而CBN刀具对黑色金属
1 research background In machining, the correct choice and application of cutting tool material is essential. There are two types of superhard tool materials: cubic boron nitride (CBN) and diamond. The highest hardness of diamond, up to 10000HV, hardness of CBN second only to diamond. Diamond tools are only suitable for non-ferrous metal materials and non-metallic materials; and CBN tool for ferrous metals
