Abstract

La présente invention améliore la précision d'usinage en maintenant de manière appropriée la distance entre : une pièce à travailler qui est maintenue par un élément de maintien ; et une partie d'usinage qui usine la pièce à travailler. L'invention concerne un dispositif d'usinage qui est destiné à usiner une pièce à travailler, le dispositif d'usinage ayant un élément de maintien en forme de plaque qui maintient la pièce à travailler et, en sandwich entre des rouleaux, comprend : des parties épaisses qui sont sur l'une ou l'autre partie d'extrémité dans une deuxième direction qui est orthogonale à une première direction, font saillie dans une troisième direction qui est orthogonale à la première direction et à la deuxième direction et s'étendent dans la première direction ; et un élément d'espacement en forme de plaque qui est fixé de manière amovible à une première surface et maintient la pièce à travailler au niveau d'une surface de maintien qui est sur le côté opposé à partir d'une surface en regard qui fait face à la première surface. Lorsque l'élément d'espacement est fixé à la première surface, les parties épaisses font face à au moins une partie de l'une ou l'autre partie d'extrémité de deuxième direction de l'élément d'espacement. La longueur sur laquelle les parties épaisses font saillie à partir de la première surface dans la troisième direction est supérieure à l'épaisseur dans la troisième direction de l'élément d'espacement fixé à la première surface.
