Electrolytic Machining Method, Manufacturing Method of Perforated Member, Electrode for Processing, and Electrolytic Machining System

摘要

The electrolytic machining method is a method of forming a bent hole in a workpiece by electrolytic machining. The electrolytic solution is circulated through an internal flow path of an electrode for processing, and the electrolyte is ejected from the outlet opening of the internal flow path provided in the front end surface of the electrode for processing. And a step of applying a potential difference between the electrode for processing and the workpiece while ejecting the electrolyte solution from the outlet opening of the electrode for processing, and a step of forming a bending hole in the workpiece, thereby ejecting the electrolyte solution. In the above, at least one of the distribution of the current density of the front end surface of the processing electrode or the flow rate distribution of the electrolyte solution ejected from the outlet opening is eccentric with respect to the shaft center of the front end surface of the processing electrode.
