Abstract

L'invention concerne un procédé de fabrication d'un dispositif de guidage linéaire, qui dispose d'une unité de guidage linéaire (2), composée d'un corps support (12) et de deux rails de guidage (13a, 13b) intégrés dans le corps support (12). Lors de l'assemblage de l'unité de guidage linéaire (2), on intègre préalablement les deux rails de guidage (13a, 13b) dans le corps support (12) de manière telle que les dispositifs de surface de guidage (8) réalisés sur ceux-ci, servant à guider un chariot de guidage, présentent encore une distance de guidage (A) supérieure à celle visée. Ensuite, on guide un chariot d'étalonnage (54) le long des deux dispositifs de surface de guidage (8), qui intègre les rails de guidage (13a, 13b) dans leur position finale, de telle sorte qu'une distance de guidage (A) visée est réglée entre les dispositifs de surface de guidage (8).
