Abstract
An electrical discharge machining tool of a ring sector for an aircraft turbomachine is provided. The ring sector includes an abradable member and a support element to which the abradable member is fixed; and one or more gripping holes opening on a radially outer surface of a central body of the support element. The machining tool includes at least two machining sets chosen from groove, notch, opening, length-cutting, or abradable element electro-machining sets. The machining tool also has a gripping device for the ring sector by the gripping holes. The gripping device is configured to move the ring sector from one of the electro-machining sets to another of the electro-machining sets.
