聚晶金刚石是一种超硬和耐磨的材料,它的硬度几乎与天然金刚石相近,它的耐磨性稍优于天然金刚石。采用常规的机械磨削法加工这类材料是非常困难的。若采用我们开发的引燃式脉冲电源──电火花刃磨技术,不但可以加工聚晶金刚石刀具,而且可以加工立方氮化硼刀具,还可大大提高生产 Polycrystalline diamond is a super hard and wear-resistant material, its hardness is almost similar to natural diamond, its wear resistance is slightly better than natural diamond. It is very difficult to machine such materials using conventional mechanical grinding methods. If we use the ignition pulse power developed by us ─ ─ EDM grinding technology, not only can process polycrystalline diamond tools, and can process cubic boron nitride tool, but also greatly improve production
