摘　　要：用中性电解液进行脉冲电化学光整加工可获得良好的表面质量,探讨了加工原理和优点,并通过传统光整加工难以加工的应用案例如光亮刻字、深小孔、型面和齿轮齿面等来证明加工效果。结果表明,脉冲电化学光整加工能在数秒钟将表面粗糙度Ra0.4-1.6μm减小到Ra0·02-0.1μm。由此可见,该技术将会在现代制造业中发挥更大的作用。Top - quality surfaces are obtained by means of pulse electrochemical finishing （ PECF）in neutral electrolyte. The machining principles and advantages of PECF are analyzed. Moreover, the technique are applied to some typical cases, such as sheeny lettering, fine and deep holes and complex shaped surface finishing, as well as gear surface finishing that all are more difficult to be machined by the traditional finishing technologies. The results show that mirror -like surfaces could be gained by PECF and the surface roughness values could be reduced from about Ra 0. 4 -0.1μm to about Ra 0. 02 - 0. 1μm within several seconds. It＇s hoped that PECF will play an important role in finishing key parts in the modem manufacturing industries.
