Therefore, the spindle performs two-dimensional machining on the workpiece placed on the work table. This is because laser processing is generally not suitable for cutting or drilling thick plates and does not require three-dimensional movement. However, it is known that a thin plate can be moved in the Z-axis direction by a small distance in order to correct the shift of the focal point of the laser beam due to the work thickness or the like.

Therefore, if a metal work having such a three-dimensional shape is cut and then the surface is to be hardened by laser processing, continuous operation with one laser processing machine is impossible. However, cutting by a cutting machine tool was required. In order to eliminate the need to transfer the work from the cutting machine tool to the laser machine, to facilitate the programming of the work process, and to reduce the scale of the machine, the cutting machine tool and the laser machine are combined into a single unit.

Abstract

Une machine-outil de coupe et une machine d'usinage au laser sont combinées de manière à obtenir une machine-outil combinée pouvant alternativement effectuer des opérations de coupe et de traitement par trempe superficielle sur une pièce tridimensionnelle à usiner. Un arbre principal (28) de construction creuse présente un chemin à trou traversant (42), est mis en rotation par un moteur (30) et se déplace dans le sens de l'axe des Z. Une table de travail (22) est disposée mobile dans le sens des axes X et Y sur un lit (12) sous l'arbre principal (28). Soit un porte-outil (40) portant un outil de coupe soit un arbre (46) pourvu d'un condenseur de rayon laser (54) peut être monté de manière appropriée sur une partie (41) de serrage d'outil à l'extrémité antérieure de l'arbre principal (28) par l'intermédiaire d'un dispositif de changement d'outil (58). Un rayon laser est guidé dans le chemin à trou traversant (42) via l'extrémité arrière de l'arbre principal (28) par l'intermédiaire d'un miroir (50) et d'un conduit (52). Une direction incidente du rayon laser est une direction parallèle à l'axe Z par réglage du miroir (50). A l'aide de cet agencement, l'arbre principal (28) peut se déplacer dans le sens de l'axe Z pendant que le rayon laser reste appliqué.
