Since, according to the invention, the adjusting devices are arranged both for the B pivoting and for the movement in the Z direction in the region of the connection between the carriage and the arm, the masses required for this purpose are omitted in the cutting head region of the arm.

Abstract

L'invention concerne une machine de découpage au jet d'eau comprenant un chariot (2) mobile dans la direction X doté d'un bras (4) monté mobile dans la direction Z. La tête de découpage (5) est montée mobile dans la direction Y sur le bras (4) au moyen d'un dispositif de déplacement. Le bras (4) est monté rotatif sur le chariot (2) de manière à pouvoir effectuer une rotation B et de telle sorte que les coordonnées spatiales du point de rotation du bras (4) dans la direction X et la direction Z soient identiques à celles du point d'usinage sur la pièce. Grâce à la structure selon l'invention, lors d'une correction nécessaire du biseau de coupe et du retard de jet dans la direction X, l'ensemble du bras (4) accompagné de la tête de découpage (5) tourne sur la pièce autour du point d'usinage. Un dispositif de réglage destiné à corriger le retard de jet dans la direction X sur la tête de découpage (5) elle-même peut donc être omis.
