Abstract

L'invention vise à proposer une machine de travail dans laquelle un outil fixé à un porte-outil effectue un travail extrêmement précis. Ceci est obtenu par l'adaptation du porte-outil pour qu'il soit réglable dans la direction radiale et par la prévention d'un changement de la force centrifuge autant que possible. A cet effet, une partie de support élastique annulaire (24), ayant une extrémité fixée au porte-outil (20) et l'autre extrémité formant une extrémité ouverte (24a), est fixée au porte-outil (20). Au moins deux outils, tels que des lames de semi-finition (26a, 26b) et des lames de finition (28a, 28b), sont ajustées sur l'extrémité ouverte (24a). Un mécanisme de pression (32) est installé dans le porte-outil (20), et le mécanisme de pression (32) se déplace vers l'avant et vers l'arrière dans la direction axiale du porte-outil (20) pour presser la partie de support élastique annulaire (24), déformant l'extrémité ouverte (24a) en une forme elliptique. Lorsque l'extrémité ouverte (24a) est déformée dans la forme elliptique, les lames de semi-finition (26a, 26b) se déplacent radialement vers l'intérieur et les lames de finition (28a, 28b), vers l'extérieur.
