The electrochemical machining starting in the mid-1950s, due to the wide range of processing, high production efficiency, good surface quality, becoming one of the special processing technology is the most widely used technology. Electrochemical Finishing is one of the applications of electrochemical machining. The finishing machining is necessary to reduce the surface roughness and improve the mechanical properties of the surface layer mechanics, but also to improve the machining accuracy (including size, shape, location accuracy) of the processing method. Processing generally include burr clear the workpiece surface, rounding refinement of the surface roughness, improve the surface physical properties. Electrochemical Finishing with other finishing methods compared in some ways has obvious advantages, is expected to be widely used in some areas. In this paper, the gear end fine the whole, the study developed a higher degree of automation gear end electrochemical finishing machine bed. And machine parts made detailed, including machine tool main the electrolyte circulation filtration systems, control systems, tools cathode. Designed machine tool rigidity, and stability, which will help to ensure the accuracy of processing. The electrolyte circulation filtering system design to avoid frequent opening of the pump, without having to increase the auxiliary equipment to achieve a clear, voiced the amount of electrolyte balance, and actual proof for simple, reliable system. Used PLC control system is stable, reliable, and easy to modify the program, The the three processing mode designed to meet the actual processing requirements. As a key part of the machine tool, the tool cathode detailing its structure. Design tool on the cathode comprises two parts, capable of the upper gear, the next two end faces at the same time processing, the flow field generated to ensure the uniformity of the electrolyte solution, consistency, and the upper and lower end face of the electrolysis The liquid can be updated at the same time. Electrochemical machining, the change of the electric field is the driving force behind the changes in distribution machining gap is directly related to the efficiency and quality of processing, starting from the electric field distribution law of solving the machining gap is the basic method. The powerful finite element calculation capabilities of ANSYS software, three-dimensional and two-dimensional analysis of the electric field. Analysis draw gear peripheral corner of a larger current density, so in the design of the electrode may be chamfered or increase the processing of the gap. By calculation analysis of the relationship of the size and location of the different tools cathode can amend the design of the cathode reasonable reasonable cathode size.
