摘　　要：针对绿色制造和微细加工的需求,对一种新型微细电解加工方法——超纯水微细电解加工进行了基础研究.在试验原理的基础上,研制了试验装置,研究了阳离子交换膜促进超纯水水解离的机理及其提高电解加工过程中电流密度的因素,并通过工艺试验在不锈钢薄片上加工出微小孔,从而论证了超纯水微细电解加工的可行性.In order to develop the green manufacturing and microfabrication, an innovative micro-electrochemi cal machining （ECM） method, the electrochemical machining, in ultrapure water was studied. On the basis of experimental principle, ECM set -up was developed for engineering application. Water dissociation mechanism was found under the function of cation exchange membrane, and many factors to enhance current density were analyzed. As a result of technological test, a micro hole was machined in the thin stainless slice. It is confirmed that the electrochemical machining technology is feasibile to make use of ultrapure water as electrolyte
