Experimental study on pulse electrochemical gear finishing technology

Abstract The principle of pulse electrochemical machining is applied to the finishing of the gear tooth surface. An experimental device for pulse electrochemical tooth surface finishing with a movable shaped cathode was established. The effect of electrolyte flow rate and other process parameters on the machining quality and efficiency was studied. An experimental study on the finishing of spur gear with 33 teeth was carried out. The results show that the process can not only reduce the roughness of the tooth surface in a short time but also increase the brightness of the tooth surface.
