Title (EN) DEVICE FOR MACHINING AND FACING RESILIENT MATERIALS
(FR) DISPOSITIF D'USINAGE ET DE SURFAÇAGE DE MATERIAUX ELASTIQUES
Abstract:
(EN) A grinding device is provided for machining and facing workpiecies made of resilient or semi-resilient materials. Said device comprises means (31) for holding the workpiece being processed after the machining operation to allow facing thereof. Machining can be improved by allowing limited drift of the workpiece, providing a flexible rotational drive, applying back pressure and using a recessed grinding wheel. This device can be used particularly for machining and facing drive rollers for office machines.
(FR) La présente invention concerne un dispositif à meule pour l'usinage, et le surfaçage de pièces en matériaux élastiques ou semi-élastiques. Selon l'invention, ce dispositif comporte des moyens (31) d'immobilisation, en fin d'opération d'usinage, de la pièce en cours de traitement pour en assurer le surfaçage, l'usinage étant amélioré par diverses dispositions: un léger flottement de la pièce, une commande souple pour son entraînement en rotation, une contre-pression et l'utilisation d'une meule à évidements. Un tel dispositif est utilisable notamment pour l'usinage, y compris le surfaçage, des rouleaux d'entraînement utilisés dans les appareils pour bureautique.
