Abstract

Selon l'invention, il est prévu au moins une, de préférence deux machines-outils (1,2) pour produire des pièces d'usinage ou pour produire entièrement des éléments d'usinage complexes. Chaque machine-outil présente un corps de base (3,4) et des unités (7,8) déplaçables dessus dans le sens horizontal. Chaque unité de machine comporte un arbre moteur (13,14) maintenu dans un support (11,12) sous forme de vilebrequin, de manière à se déplacer dans le sens de l'axe de l'arbre. Ledit support est monté pivotant et maintient chaque arbre au-dessus du système de transport (31,32) respectif prévu pour une pièce ou un élément d'usinage (37,38). Dans la zone fonctionnelle d'une de ces machines-outils, il est prévu des dispositifs d'usinage, par exemple sous forme de porte-outil (44) pour outils de tournage, d'alésage et/ou de fraisage, de dispositif de soudage laser (46), de dispositif de rectification (47) et de dispositif de brossage (48), ainsi que de dispositif d'assemblage.
