Title (EN) ELECTRO-EROSION CUTTING MACHINE FOR FINAL TREATMENT OF STAMPING AND CUTTING TOOLS
(FR) MACHINE A DECOUPER A ELECTRO-EROSION POUR LE TRAITEMENT FINAL DES OUTILS A ETAMPER ET A DECOUPER
Abstract: front page image
(EN)Erosion cutting machine for cutting closed concave or convex forms (15; 16) from a work piece (12) fixed to a support; to that effect, a wire or band electrode (14) is used, which is fixed to guiding means (13, 18). At least one guiding means (13, 18) is arranged on a rotary motor device (20), so that the center line (23) of the rotary device (20) is in register, at least on one geometric location, with the center of the section of electrode (14). Thereby, a collision of the guiding means (13, 18) with the forms (15, 16) or even with a support (11) is avoided during the erosion process.
(FR)Machine a usiner a erosion pour decouper des formes concaves ou convexes fermees (15; 16) d"une piece (12) a usiner fixee a un support; on utilise pour ce faire une electrode (14) en forme de fil ou de bande fixee a un moyen de guidage (13, 18). Au moins un moyen de guidage (13, 18) est dispose sur un dispositif rotatif motorise (20), de telle facon que la ligne mediane (23) du dispositif rotatif (20) coincide en au moins un endroit geometrique, avec le centre de la section de l"electrode (14). Par ce moyen, on evite une collision des moyens de guidage (13, 18) avec les formes (15, 16) ou meme avec un support (11), durant le procede d"erosion.
