Abstract

La présente invention concerne un outil d'usinage rotatif qui comprend un moyeu rotatif (10) qui supporte une pluralité d'éléments d'outil (14) autour de sa périphérie extérieure pour usiner une pièce au niveau d'une région de contact prédéterminée de l'outil ; une pluralité de passages (26) qui s'étendent vers l'extérieur à partir d'une chambre intérieure (22) du moyeu (10) à un angle non orthogonal par rapport à l'axe de moyeu (12) afin de sortir au niveau de la périphérie extérieure du moyeu entre des paires respectives d'éléments d'outil adjacents (14) ; et une tuyère (28) disposée à l'intérieur de la chambre intérieure (22) de façon adjacente au passage rotatif des extrémités intérieures des passages de moyeu (26) et conçue pour fournir un lubrifiant fluide dirigé à l'intérieur des passages de moyeu (26) sans interaction du fluide avec une autre partie de la surface de moyeu de roue et qui le force dans non plus de deux des passages (26) à un instant quelconque lorsque le moyeu est tourné, de sorte que le lubrifiant fluide soit éjecté entre des éléments d'outil (14) sensiblement uniquement au niveau de la région de contact prédéterminée de l'outil.
