【摘要】 本文对各种可能的成型加工聚晶金刚石的方法进行了探讨和研究。分析表明,放电加工是粗、半精成型加工聚晶金刚石的有效途径。作者提出了一种创新的加工方法,适合于成型加工含有导电粘结剂的聚晶金刚石、金属陶瓷等所有导电的超硬材料。试验结果表明,用新方法加工聚晶金刚石,效率高达2.5mm~3/min以上,加工表面粗糙度 R_z在10μm左右,是一种十分有效的方法,并且具有设备简单、性能稳定、工作可靠、成本低廉等特点。更多还原

【Abstract】 In this paper, almost every possible method for machining polycrystallinediamond was analysised and tested. The result shows that electro-discharge mach-ining is the most effective method for rough and semi-finish machining of PD.The authors have presented a new method which can be used to machine all super-hard materials with conductive bond, such as PD, metal-ceramic,etc. It is provedthat the removal rate of PD with the new method is as high as 2.5mm³/min,and the surrace roughness is about R₂ 10μm. The method is very efficient andcharacterized by it s simple principal, steady performance, and low equipmentand machining costs.更多还原
