Abstract

L'invention concerne une machine à rectifier comportant un dispositif de dressage de meule Elle comporte un détecteur de position initiale absolue du porte-meule et un dispositif à mémoire non volatile qui mémorise une position initiale transitoire. Lorsqu'un cycle de dressage de la meule est exécuté, la valeur d'avance au cours de ce cycle est ajoutée à la valeur représentant la position initiale transitoire de manière à compenser la diminution du rayon de la meule due à l'opération de dressage. L'invention s'applique notamment à des machines à rectifier les arbres à cames.The invention relates to a grinding machine comprising a grinding wheel dressing device. It comprises a detector of the absolute initial position of the grinding wheel holder and a non-volatile memory device which memorizes a transient initial position. When a grinding wheel dressing cycle is performed, the feed value during that cycle is added to the value representing the initial transient position so as to compensate for the decrease in the grinding wheel radius due to the dressing operation . The invention applies in particular to machines for grinding camshafts.
