超硬材料刀具(即人造金刚石复合、立方氮化硼复合刀具),广泛应用于切削加工高强度、高硬度、金属与非金属难加工的材料,对有色金属材料进行高精度,高光洁度切削加工,可取代磨削加工,具有超硬特性、高稳定性、高化学惰性与高导热性等独特优点。耐用度是普通硬质合金材料的30—50倍。世界科学技术的进步带来材料工业的不断发展,一些特殊性能和用途的材料相继出现,对机械加工提出越来越高的要求,同时机械工业本身的发展也急需使用高效率、高精度、高硬度和高耐用度的新型刀 Ultra-hard materials, tools (that is, synthetic diamond composite, cubic boron nitride composite tool), widely used in cutting high strength, high hardness, metal and non-metallic materials difficult to process, non-ferrous metal materials for high-precision, high-finish machining , Can replace the grinding process, with super-hard features, high stability, high chemical inertness and high thermal conductivity and other unique advantages. Durability is 30-50 times more than common carbide materials. Progress in the world of science and technology has led to the continuous development of the material industry, some of the special properties and uses of materials have emerged, put forward higher and higher machining requirements, while the machinery industry itself is also in urgent need of the development of high efficiency, high precision, high Hardness and high durability of the new knife
