Abstract

Dispositif pour l'usinage électrochimique d'évidements dans une pièce conductrice constituant l'anode. Au moins une électrode conformatrice, solidaire d'une table fixe, est située à l'intérieur d'une cavité déterminée par un guide en matière synthétique non conductrice; ce guide comporte une partie supérieure de plus faible dimension dans laquelle est disposée une ouverture centrale aux dimensions de la pièce à usiner ; un support creux en matière synthétique isolante, susceptible de coulisser sur la partie supérieure du guide, est ouvert à son sommet; une coiffe en matière synthétique isolante comporte une ouverture à sa partie supérieure lui permettant d'être traversée par ledit support ; au moins un élément conducteur, relié au pôle positif d'un générateur et mobile dans un guide isolant, est situé face à l'électrode conformatrice, solidaire d'un plateau mobile en direction de la table fixe. Application à l'usinage électrochimique.
