Abstract
CET OUTIL PEUT ETRE FIXE DANS LE MANDRIN D'UNE MACHINE-OUTIL ET COMPREND UNE TIGE 2 SUR LAQUELLE PEUT GLISSER AXIALEMENT UNE ELECTRODE FLEXIBLE 24 ET QUI PRESENTE INTERIEUREMENT UN CONDUIT 35 POUR AMENER UN FLUIDE ELECTROLYTIQUE A LA PIECE A USINER. L'EXTREMITE DE TRAVAIL DE L'OUTIL EST CONSTITUEE PAR UNE TETE DE GUIDAGE DETACHABLE 25 QUI DEFINIT UN PASSAGE DE GUIDAGE 43 PARTIELLEMENT EN ARC DE CERCLE POUR L'ELECTRODE, DE MEME QUE LES TRONCONS EXTREMES 39, 40 DU CONDUIT 35. L'ELECTRODE EST GUIDEE DE MANIERE QUE SON BOUT LIBRE 24A DEPASSE A PEU PRES RADIALEMENT DU SUPPORT FORME PAR LA TIGE 2 ET LA TETE 25, L'ANGLE ENTRE CE BOUT ET L'AXE DU SUPPORT ETANT DEFINI PAR LE RAYON DE COURBURE DU PASSAGE 43. LA TETE 25 PEUT ETRE REMPLACEE PAR AU MOINS UNE AUTRE TETE DONT LE PASSAGE 43 POSSEDE UN RAYON DIFFERENT. L'INVENTION EST NOTAMMENT APPLICABLE AU CREUSEMENT DE CAVITES EN FORME DE CHAMPIGNON DANS DES SOUPAPES POUR MOTEURS A COMBUSTION INTERNE.
