YANG Zhao-jun~1 ZHANG Li-xin~(1,2) WANG Li-hui~1 (1.College of Mechanical Science and Engineering,Jilin University,Changchun 130022,China; 2.College of information Engineering,Jilin Teachers Institute of Engineering and Technology,Changchun 130052,China)  
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.
