Abstract

L’invention se rapporte à un outil rotatif (1) pour la retouche d’une pièce (124a) par usinage, l’outil s’étendant selon un axe central longitudinal (2) correspondant à son axe de rotation, le long duquel cet outil comprend une queue d’outil (4) suivie d’une portion de travail (6). Selon l’invention, la portion de travail (6) comprend plusieurs têtes d’usinage (10a-10c) se succédant selon l’axe central longitudinal (2), deux têtes d’usinage (10a-10b) quelconque et directement consécutives de la portion de travail étant séparées l’une de l’autre par une zone de jonction sécable (12), de section réduite par rapport à celle des deux têtes d’usinage. Figure pour l’abrégé : Figure 8.
