Abstract

Méthode servant à l'usinage électrochimique d'une pièce (10) et utilisant un électrolyte qui passive la pièce (10), l'outil conducteur (20) étant muni d'une surface abrasive non conductrice (24). Ledit outil (20) et ladite pièce (10) sont réunis par un mouvement relatif de mise en contact de façon que ladite surface abrasive (24) abrase sélectivement la pièce (10) pour éliminer toute couche de passivation sur les zones de la pièce devant être usinées; les zones de la surface non abrasées conservent la couche de passivation, ce qui permet d'éviter ou de retarder l'usinage électrochimique. La composante réciproque du mouvement relatif entre l'outil (20) et la pièce (10) pompe l'électrolyte à travers l'espace situé entre l'outil (20) et la pièce (10) et empêche la surchauffe de la pièce.
