立方氮化硼和多晶金刚石之类超高压烧结工具材料,美国通用电器公司在1973～1974年就已研制成功。经过近年来的迅速发展,这类特殊工具材料不断推广普及,似将成为普通工具材料。作为一代新型工具材料,它的出现势必对整个切削技术带来巨大的影响。现在欧美和日本等主要工业国家对于研制和应用超高压烧结工具非常重视。特别是在日本,近来出现了很多生产超高压烧结工具的厂家,产量急剧上升,并且研制了一些独特的产
Cubic boron nitride and polycrystalline diamond ultra-high pressure sintering tool material, the United States General Electric Company in 1973 ~ 1974 has been successfully developed. After the rapid development in recent years, this kind of special tool material has been popularized and popularized constantly, it seems to become a common tool material. As a new generation of tooling material, its appearance is bound to have a huge impact on the cutting technology. At present, major industrialized countries such as Europe, the United States and Japan attach great importance to the development and application of ultra-high pressure sintering tools. In Japan, in particular, there have been many recent manufacturers of ultra-high pressure sintering tools that have experienced a dramatic increase in production and have developed some unique products
