聚晶金刚石是一种新型超硬材料。它的硬度和天然金刚石相近,耐磨性比天然金刚石还好,因此在切削刀具。石油地质钻头,拉丝模等方面得到广泛的应用。因聚晶金刚石材料超硬耐磨,所以将其制成各种成型工具的加工技术是近年来世界各国极其重视的科研课题。北京市电加工研究所曹凤国、孙琏妮、李小兵、王燕春等同志根据对聚晶金刚石物理性能的分析,采用不同于普通电火花加工的脉冲波形和工艺参数,大幅度增加放电击穿爆炸力进行放电加工,并研制了BDDG-1型加工聚晶金刚石专用电源设备,从而能高效率、高质量将聚
Polycrystalline diamond is a new type of superhard material. Its hardness and natural diamond are similar, abrasion resistance is better than natural diamond, so cutting tools. Petroleum geological drill bit, drawing die and so has been widely used. Polycrystalline diamond material due to superhard wear-resistant, so it will be made into a variety of molding tools processing technology in recent years the world has attached great importance to scientific research topics. Based on the analysis of the physical properties of polycrystalline diamond, Cao Fengguo, Sun Jini, Li Xiaobing and Wang Yanchun from Beijing Electric Processing Research Institute used different pulse shapes and process parameters than ordinary EDM to greatly increase the discharge breakdown explosive force EDM processing, and developed BDDG-1 processing polycrystalline diamond dedicated power equipment, which can be efficient, high-quality will be poly
