Pulse Electrochemical Finishing removes the metal of the surface by electrochemical dissolution. Because of no cutting force, cutting heat, there are no cutting mark, plastic deformation layer on the surfaces of the parts.

• 脉冲电化学光整加工以离子溶解形式去除工件表层金属，加工中因为没有切削力和切削热的作用，所以加工后的工件表面与机械加工表面相比无附加切削痕迹、塑性变形层。
