Abstract

L'invention concerne une machine-outil susceptible de tailler des collets circulaires. La machine selon l'invention comporte une deuxième tête porte-outil, des moyens permettant de la faire tourner, des moyens permettant de la déplacer de façon que la pièce à usiner puisse subir en même temps l'action de la première et de la deuxième tête. Application à la fabrication des machines-outils.The invention relates to a machine tool capable of cutting circular collars. The machine according to the invention comprises a second tool-holder head, means allowing it to be rotated, means allowing it to be moved so that the part to be machined can undergo at the same time the action of the first and of the second head. Application to the manufacture of machine tools.
