Abstract

L'invention vise à améliorer un tour comportant un châssis, un carter de broche qui est disposé sur le châssis et dans lequel une broche porte-pièce est montée pivotante autour d'un axe de broche, et au moins une unité fonctionnelle conçue comme porte-outil et/ou dispositif de transport de pièce, de manière à ce que l'usinage d'une pièce soit le plus efficace possible. A cet effet, le carter de broche est un élément support qui est disposé sur un côté d'un espace de travail de manière contiguë et sur lequel sont montées plusieurs unités fonctionnelles.
