Abstract

La présente invention concerne un centre d'usinage (30) destiné à l'usinage de pièces (38), comprenant au moins un espace d'usinage (32), dans lequel est disposée une machine-outil (10) servant à l'usinage par enlèvement de copeaux de pièces (38) avec au moins une broche de travail, au moins un espace de montage (40), dans lequel une pièce (38) à usiner peut être montée dans au moins un système de serrage (37) à l'aide d'un moyen de serrage (28) en vue de l'usinage et dans lequel une pièce (38) usinée peut être prélevée du système de serrage (37), et une bande de coulissement (36), qui s'étend linéairement dans l'espace d'usinage (32) depuis l'espace de montage (40) et le long de laquelle est monté l'au moins un système de serrage (37) de manière à pouvoir coulisser entre l'espace de montage (40) et l'espace d'usinage (32). L'au moins un système de serrage (37) permet de faire coulisser la pièce (38) à usiner sur la bande de coulissement (36) pendant l'usinage par rapport à la broche de travail.
