聚晶金刚石车刀和镗刀是一种新型刀具。由于它具有超硬特性,解决了某些硬质合金或陶瓷、立方氮化硼等刀具所不能解决的关键问题,使生产效率、刀具寿命成倍提高,从而降低了产品成本,保证了工件精度。一、聚晶金刚石刀具的特点及使用范围特点:这种刀具是将聚晶金刚石块经过特殊钎焊和刃磨工艺而制成的超硬刀具。而聚晶金刚石块是采用人工或天然金刚石微粒加上一定量的金属微粉作粘结剂,然后,经高温、高压制成具有一定几何形状和尺寸的聚晶块,具有近
Polycrystalline diamond turning tools and boring tools is a new type of tool. Due to its super-hard properties, it solves the key problems that can not be solved by some cemented carbide, ceramic, cubic boron nitride and other knives, which leads to double the production efficiency and the tool life, thus reducing the product cost and ensuring the accuracy of the workpiece . First, the characteristics of polycrystalline diamond cutting tools and the use of Features: This tool is polycrystalline diamond block through a special brazing and grinding process made of superhard cutting tools. The polycrystalline diamond block is the use of artificial or natural diamond particles plus a certain amount of metal powder as a binder, and then, by high temperature, high pressure made of a certain geometry and size of the polycrystalline block, with near
