ABSTRACT:
A method and a device for finishing the cut surface of a work which is cut from a metal blank by a wire cut discharge process. The work and the waste piece of the metal blank are positioned in the same condition as just after the process. Electrolyte is fed through a clearance between the work and the waste piece and, at the same time, current is caused to flow from the work to the remainder. This subjects the cut surface of the work to electrolytic treatment to thereby make it smooth while removing oxide films and degenerated surface layers therefrom.
