Abstract

L'invention concerne un procédé et un dispositif pour l'usinage par étincelage. Pendant une première phase d'usinage, on déplace les électrodes 1 et 2 selon un mouvement de translation effectué au moins après la pénétration de l'outil 1 dans la pièce 2, jusqu'à une excentricite limite. On diminue ensuite cette excentricite et on remplace, au moyen d'une vanne 8, le fluide diélectrique par un électrolyte pour effectuer un polissage électrolytique.
