摘　　要：提出了线切割加工导电工程陶瓷回转表面的新工艺.对普通快速走丝线切割机进行了改造,在机床上加装带动工件回转、并能传递加工电流的工件主轴装置,实现了对工程陶瓷复杂回转表面的放电加工.采用正交多项式回归设计对线切割放电加工碳化硼陶瓷回转表面的工艺参数进行优化,得到了较低的表面粗糙度,验证了线切割放电加工导电工程陶瓷回转表面新工艺的可行性.A novel technology of wire electro-discharge machining （WEDM） rotary surface of engineering ceramic is presented in this paper. The common high-speed WEDM is advanced, and the current can be transmitted by the workpiece spindle machining device to achieve the complexity of the engineering ceramic rotary surface. The process parameters of WEDM boron carbide ceramic rotary surface are optimized by orthogonal polynomial regression design, and the lower surface roughness and the feasibility of new technology that WEDM conductive ceramic rotary surface is further validated.
