Abstract

On forme au moins un évidement (10) en secteur angulaire dans la partie d'extrémité (2A) du manchon cylindrique (2) travaillée en fin d'usinage, de telle sorte que lorsque l'outil d'usinage de l'alésage (2B) du logement (2) vient à la hauteur dudit évidement (10) en secteur angulaire l'outil d'usinage n'enlève plus de la matière sur une circonférence complète, ce qui a pour résultat de briser « l'anneau de copeau » résiduel formé en fin d'usinage en petits copeaux (30) qui peuvent ensuite être évacués par des moyens classiques de lavage. Véhicules automobiles. Culasses à distribution à attaque directe de véhicules. Usinage des culasses des véhicules automobiles.
