Abstract
L'invention concerne une machine à rectifier sans centre. Cette machine comprend un bâti, une meule de travail et une meule d'entraînement qui forme entre elles une extrémité d'entrée et une extrémité de sortie des pièces, un support de pièce placé entre les meules, un pivot proche de l'extrémité d'entrée, un dispositif destiné à faire pivoter l'une des meules par rapport à l'autre sur ledit pivot, pendant la rectification, un dispositif destiné à déplacer axialement la pièce par rapport aux meules, pendant la rectification, et un dispositif d'avance par pivotement, faisant varier les distances d'avance le long de la face de la meule d'entraînement par rapport à la meule de travail, de l'extrémité d'entrée vers l'extrémité de sortie. Domaine d'application : fabrication de ressorts pour suspensions progressives de véhicules.
