ELECTRODE, ELECTROCHEMICAL MACHINING DEVICE USING AFOREMENTIONED ELECTRODE, ELECTROCHEMICAL MACHINING METHOD, AND MACHINED ARTICLE MACHINED BY MEANS OF SAID METHOD

摘要

This electrode (4) is provided with: a core tube (41) that uses a material capable of forming a second hole (101b), which differs in direction or in curvature from a first hole (101a) formed with a predetermined curvature, in a manner joined to the first hole (101a); and a covering (42) adhered to the outer periphery of the core tube (41). As a result, an electrode having a high degree of freedom in machining shape and having a simple structure, an electrochemical machining device using the electrode, and an electrochemical machining method are achieved.
