Abstract

L'objet de l'invention se rattache au secteur technique des machines-outils. Le mandrin est caractérisé en ce que la bague solidaire de la broche reçoit à coulissement élastique un disque en matière de bonnes caractéristiques d'adhérence entraînant l'organe porte-pièces à la vitesse de la broche; en fin de course du disque, le cône-mâle de l'organe porte-pièce étant alors en contact avec le cône-femelle de la bague tournant avec la broche. L'invention s'applique principalement aux tours.
