Research on Electrochemical Machining Technology of Deep Small Hole using Suction Electrode

Abstract

Aiming at the problem of deep small hole machining for difficult-to-machine material, a suction electrode electrochemical machining method is used to solve the problems of slow electrolyte renewal and poor stability during the electrochemical machining of deep small holes. This paper mainly uses the multi-physics coupling software COMSOL to establish a multi-physics coupling model for the electrochemical machining of deep small holes with a suction electrode and simulates the forming process of the deep small hole and the distribution of the flow field and electric field during the machining process. This model verifies the feasibility of electrochemical machining technology of deep small holes using a suction electrode.
