多年来,切削加工光学组件都用单晶金钢石。用此加工的工件不仅表面光洁度好,而且外形误差可小至R(?)=5nm或254nm。此外,诸多材料,尤其是应用于光学工业的材料如黄铜、银、硼、金、铍-铜合金和其他铜合金、化学镍、石墨、塑料、硅铜、锗、锌合金、锂-铌合金、镓-砷等都适于用单晶金钢石切削加工。单晶金钢石刀具有着许多特殊性能:硬 Over the years, cutting optical components are used single crystal diamond. Workpieces machined with this finish not only have a good surface finish, but also have a low profile error of R (?) = 5 nm or 254 nm. In addition, many materials, especially those used in the optical industry such as brass, silver, boron, gold, beryllium-copper alloy and other copper alloys, chemical nickel, graphite, plastic, silicon copper, germanium, zinc alloy, Alloy, gallium arsenic, etc. are suitable for single crystal diamond cutting. Single crystal diamond tools have many special properties: hard
