间歇冲液脉冲电化学精密扩孔新技术

Pulse Electrochemical Finishing with Intermittent Flush for Small Hole

本文提出了间歇冲液微秒级脉冲电化学精密扩孔新方法，介绍了其工作原理和加工装置的组成。实验表明，该方法可实现微米级无应力加工，并且被加工表面十分光亮。

This Paper Proposes a new method of electrochemical finishing for small hole with microsecond pulses.In this method, the interelectrode gap was flushed out by electrolyte during the pulse off-times between two pulses or two groups of pulses.Experiments show that the method is capable of micrometer-scale machining without heat affected layers and stress, and obtaining smooth lustrous surface.
