Abstract

L'invention concerne un découpage par abrasif où un abrasif (B) et un milieu d'entraînement (A) sont amenés dans une buse (2). Le milieu d'entraînement (A) en entrant dans la buse (2) est formé en un anneau (8), qui couvre la surface interne de la buse (2). Grâce à à la dépression créée, l'abrasif (B) est aspiré depuis la ligne d'alimentation (4) pour, ensuite, être entraîné à l'intérieur de l'anneau (8) du milieu d'entraînement (A). Le dispositif (1) présente une extrémité de sortie (7) d'une ligne d'alimentation (4) pour l'abrasif (B), montée à l'intérieur de la buse (2) et coaxialement par rapport à son axe, de manière à ce que l'anneau circulaire (6) créé entre la surface interne de la buse (4) et le diamètre externe de la ligne d'alimentation (4), ait une longueur d'au moins 1 mm.
