The invention relates to a method for grinding metallic workpieces containing, in particular, nickel, whereby a rotationally driven grinding wheel (2) is continuously dressed by a rotationally driven dressing wheel (3) during the grinding of the workpiece (1) by the continual advance (vfrd) of the dressing wheel. In order to increase the grinding capacity, the invention provides that with a dressing advance velocity of 1 to 2 µm per rotation of the grinding wheel and with a circumferential velocity of the grinding wheel (vs) of at least 45 m/s, the advance (table velocity vt) is set such that the rate of metal removal is at least 90 mm3/mms.
L'invention concerne un procédé permettant de meuler des pièces métalliques contenant notamment du nickel, selon lequel une meule (2) entraînée en rotation, d'une roue de dressage (3) entraînée en rotation est dressée en continu pendant le meulage d'une pièce (1), par approche continue (cfrd) de la roue de dressage. Afin d'augmenter la capacité de meulage, il est prévu d'ajuster l'avance, pour une vitesse d'approche de dressage allant de 1 à 2 µm par rotation de la meule et pour une vitesse périphérique de la meule (vs) d'au moins 45 m/s, de sorte que le taux d'enlèvement de copeaux soit d'au moins 90 mm?3¿/mms.
