Abstract

L'objectif de la présente invention est d'éviter la déviation d'un rail de guidage, qui supporte de façon mobile une partie d'usinage pour usiner une pièce, en raison d'une force de réaction produite de manière concomitante avec une action d'usinage effectuée par la partie d'usinage, et ainsi d'améliorer la précision d'usinage. Dans un dispositif d'usinage pour usiner une pièce : un chariot qui maintient une partie d'usinage pour usiner la pièce est supporté sur un rail de guidage de manière à être mobile dans une deuxième direction ; le rail de guidage comprend une partie corps principal s'étendant dans la deuxième direction, et une partie de guidage qui s'étend dans la seconde direction et qui est reliée à un premier côté, dans une troisième direction, de la partie corps principal ; la partie corps principal et la partie de guidage sont reliées l'une à l'autre dans au moins un emplacement entre une paire de cadres latéraux ; et le chariot est pourvu d'une partie de mise en prise qui est positionnée entre une partie de support et la partie de guidage dans la troisième direction, a une section transversale, orthogonale à la deuxième direction, qui forme une forme d'arc circulaire ayant une partie d'ouverture sur le côté rail de guidage, qui est l'autre côté dans la troisième direction, et qui vient en prise avec la partie de guidage de manière à pouvoir coulisser dans la deuxième direction.
