US 2026/0216804 A1 · ELECTROCHEMICAL MACHINING TOOL, ELECTROCHEMICAL MACHINING DEVICE, AND BLADE MANUFACTURING METHOD

Abstract

The present invention has: a tool electrode that is cylindrical around the tool axis and that forms an electrolytic solution passage on the inner circumferential side thereof; and an insulating layer that is formed on the outer circumferential surface of the cylindrical tool electrode. The electrolytic solution passage has: an outlet that is formed at the end on a first side, among the first side and a second side in the axis direction in which the tool axis extends, within the tool electrode; and a diameter expansion portion in which the inner diameter thereof increases gradually toward the first side. The end on the first side in the diameter expansion portion is said outlet.
