天然金刚石单晶车刀是超精密切削加工中最理想的刀具之一,在金刚石车刀和其他金刚石工具的制造和使用过程中,都存在一个如何将金刚石晶体固定在夹具或刀体上的问题。国内最普遍采用的制造工艺是:先将不规则的金刚石晶体经定向后(用夹具直接夹持),粗加工成规则的六面体刀坯,再进行刀具切削部的修磨与精抛,用机械夹固或粘接的方法将金刚石刀固定在刀杆上。这种方法主要有两个缺点。一是金刚石的加工量较大,天然 Natural diamond single crystal turning tool is one of the most ideal cutting tools in ultra-precision machining. There is a problem of how to fix the diamond crystal on the fixture or the cutter body during the manufacture and use of diamond turning tools and other diamond tools . The most commonly used manufacturing process in China is as follows: the irregular diamond crystal is first routed (directly clamped by the clamp), roughed into a regular hexahedron blanks, and then the grinding and polishing of the cutting part of the cutter are carried out with a mechanical Clamping or bonding method will be fixed to the diamond knife on the arbor. This method has two major disadvantages. First, a larger amount of diamond processing, natural
