摘　　要：采用块状工具电极的精密电火花磨削加工法是低刚度轴和微细轴类零件电火花加工的主要方法之一 ,该方法过去采用的是径向进给方式。由于电极损耗的因素 ,使得工件的形状和尺寸的一致性不好 ,且对生产率也有影响。本文采用一种新的块状工具电极的进给方式———切向进给方式 ,利用伺服进给自动补偿电极损耗 ,大大地提高了成批加工工件的一致性和生产率。It is one of main methods in EDM of the low stiffness and micro shaft parts that adopting block electrode in precision electrical discharge grinding. The mode of radial feeding is used ever, but it can not get the good shape of parts and conformance of size and influence the productivity even. In this paper, a new feeding mode of block electrode is adopted that is the mode of tangent feeding. It can enhance the conformance and productivity of machining parts in batches by using servo-feeding system to compensate the reduction of electrode wear automatically.
