Abstract

L'invention a pour objet l'amélioration d'un tour comprenant un bâti de machine, une unité de broche porte-pièce disposée sur le bâti de machine avec un logement de pièce pouvant être entraîné par rotation autour d'un axe de broche porte-pièce pour une pièce à maintenir dans une position de pièce, un porte-outil pouvant être déplacé par rapport au bâti de machine, sur lequel est disposée une pluralité d'emplacements de logement d'outils pour des outils, de telle sorte que le tour soit conçu le plus compact possible. A cet effet, le porte-outil peut être déplacé parallèlement à un plan de déplacement agencé transversalement à l'axe de broche porte-pièce uniquement en direction de deux axes de déplacement agencés transversalement l'un par rapport à l'autre, les outils et les emplacements de logement d'outils sont disposés de telle sorte que les lames des outils sont disposées dans une direction parallèle au plan de déplacement sur un côté, tourné vers la pièce, des emplacements de logement d'outils et des outils individuels peuvent être sélectionnés uniquement en déplaçant le porte-outil dans le plan de déplacement à partir d'au moins une partie des outils attribués aux emplacements de logement d'outils et peuvent être amenés dans au moins une position d'usinage pour l'usinage de la pièce en direction de l'axe de broche porte-pièce.
