Abstract

L'invention concerne un dispositif pour faire passer un courant électrique pulsé dans la zone d'usinage comprise entre une électrode-fil 1 et une électrode pièce 2 dans une machine à usiner par étincelage érosif. Ce dispositif comporte deux frotteurs 9, 10 et un condensateur 19 connecté entre ces frotteurs. Le frotteur 10 fait contact avec un plateau métallique 11 fixé sur le bâti 5 de la machine et relié galvaniquement à la pièce 2 et à une borne A du générateur d'impulsions. Le condensateur 19 est chargé périodiquement et se decharge dans la zone d'usinage en créant des impulsions de courant à fronts raides et de courte durée. Application usinage par électro-érosion.
