Research on Technology and Application of Pulse Electrochemical Finishing
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, gear surface finishing that all of them are more difficult to be machined by the traditional finishing technologies. The results show mirror-like surfaces could be gained by PECF and the surface roughness values could be reduced from more than Ra 0.8 μm to less than Ra 0.08 μm within 1~2 seconds. It’s hoped that PECF will play an important role in finishing key parts in the modern manufacturing industries.
