Abstract: Special features of the binary electrical layers of the electrode interface in ECM were analyzed. Aiming at the cathode design, influence of the depolarization of electrode surfaces on the electrode process and improvement in the precision of ECM through changes in the fluid field and in the distribution of eiec- trical current on the electrode surfaces were discussed. A method was proposed to improve the machining precision of ECM through changes in the gap electrical field distribution by the magnetic field. Microscopi?cally, the magnetic field affects the molecular structure of the electrolyte and the direction of movement of the charged ions. The effect affects the electrode process and the gap electrical field, which in turn reduces the dispersive corrosion and fluid wrinkles in ECM.
