Abstract
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.
