Abstract

L'INVENTION CONCERNE LES OUTILS DE COUPE DE METAL. UN OUTIL DE BROCHAGE COMPORTE ESSENTIELLEMENT UN CORPS 20 MUNI D'UN CERTAIN NOMBRE DE CAVITES DANS LESQUELLES SONT LOGES DES DISQUES DE COUPE 24. CES DISQUES ONT UNE TRANCHE DE FORME GENERALE CONCAVE QUI FORME UN ANGLE AIGU AVEC LES FACES D'EXTREMITE DES DISQUES. ON CHOISIT CET ANGLE AINSI QUE L'INCLINAISON DU DISQUE PAR RAPPORT A L'AXE LONGITUDINAL DE L'OUTIL DE FACON A OBTENIR UN ANGLE DE GROUPE POSITIF DE 1 A 25 ENTRE LA PARTIE COUPANTE DU DISQUE ET LA PIECE USINEE. APPLICATION AUX OPERATIONS DE BROCHAGE.THE INVENTION CONCERNS TOOLS FOR CUTTING METAL. A BROACHING TOOL ESSENTIALLY INCLUDES A BODY 20 PROVIDED WITH A NUMBER OF CAVITIES IN WHICH CUTTING DISCS ARE HOUSED 24. THESE DISCS HAVE A SLICE OF CONCAVE GENERALLY SHAPE WHICH FORMES A SHARP ANGLE WITH THE END FACES OF THE DISCS. THIS ANGLE IS CHOSEN AS WELL AS THE INCLINATION OF THE DISC IN RELATION TO THE LONGITUDINAL AXIS OF THE TOOL SO AS TO OBTAIN A POSITIVE GROUP ANGLE OF 1 TO 25 BETWEEN THE CUTTING PART OF THE DISC AND THE MACHINED PART. APPLICATION TO BROACHING OPERATIONS.
