The gear finishing and finishing is to improve gear accuracy and tooth quality of the main means. Electrochemical mechanical finishing (ECMF) has high leveling efficiency and leveling ability. It is important to solve the problems of gear precision and tooth surface by using electrochemical mechanical finishing technology for cylindrical gear machining significance. The developing mode of gear ECMF was proposed. The influence of process parameters on the roughness of tooth surface was studied. The influence of spread electrochemistry mechanical processing on gear tooth profile, tooth profile and tooth profile accuracy was studied. The results show that the cylindrical gear forming electrochemical mechanical finishing can reduce the Ra value of the tooth surface roughness from more than 1.0μm to less than 0.1μm, compared with the pre-processing indicators, the tooth profile characteristics are improved, Accuracy increased by 2, tooth profile and tooth accuracy has also been improved.
