Abstract

La présente invention concerne une machine d'usinage laser pour l'usinage d'un tube (4) au moyen d'un faisceau laser. La machine comporte des moyens pour mouiller et/ou pour refroidir la paroi interne d'un tube avant ou pendant l'usinage laser. Les moyens cités comprennent une tuyère (9) pour liquide. La tuyère (9) est placée dans le sens longitudinal du tube (4), devant l'emplacement d'usinage du faisceau laser, et produit un cône de liquide, lequel atteint la paroi interne du tube à la fois à la hauteur de l'emplacement d'usinage du faisceau laser et, également, sur le côté qui est diamétralement opposé à l'emplacement d'usinage du faisceau laser. Dans le cadre d'un procédé d'usinage mécanique d'un tube (4) au moyen d'un faisceau laser, la tuyère (9) est introduite dans le tube (4) dans son sens longitudinal jusqu'à ce qu'elle se trouve devant l'emplacement d'usinage du faisceau laser. Ensuite, la tuyère (9) produit le cône de liquide décrit précédemment.
