Electrochemical Finishing On Gear End Faces And Study Of The Distribution Of Electic Field And Flow Field

Electrochemical machining was applied in the middle of last fiftieth. Because of widely application, high efficiency, high surface quality, it had become one of the most extensively applied nontraditional processing. Electrochemical finishing is one application of electrochemical machining. Finishing is a machining to lower surface roughness, to improve mechanics engineering properties and to enhance machining precision including size, shape and location precision. The processing commonly includes removing surface burrs, rounding, refining surface roughness and improving surface physical property. Electrochemical fining has obvious advantage than other fining methods in some aspects, and will be widely applied in some fields.This paper research and manufactured electrochemical fining machine tool, which have higher automation extent aiming at gear end face fining. The paper detailedly describes kinds of parts of the machine tool including the main body of the machine, electrolyte circulating and filter system, control system, tool cathode. The designed machine tool has good rigidity and stability, which benefits to the machining precision. The designed electrolyte circulating and filter system avoids to frequently turn on and off the pump, and could maintain the balance of clear electrolyte and turbid electrolyte without increasing assistant equipments. It is proved a sample and stable system by practice. The PLC control system is stable, reliable and easy to amend programs. And the three machining modes satisfy the need of practice machining. Tool cathode is the key part of the machine. The paper detailedly describes the construction. The tool cathode includes top and bottom parts, and can machining two end face at the same time. The produced flow field can maintain electrolyte uniformity and consistency, and can update top and bottom electrolyte at the same time.
