Title (EN) AN APPARATUS FOR DRESSING A GRINDING WHEEL
(FR) APPAREIL DE DRESSAGE DE MEULE
Abstract:
(EN) An apparatus (1) for dressing a grinding wheel (2) mounted thereon by creating structures (12) on the surface of a, in particular cylindrical, grinding surface (3) of the grinding wheel (2), the apparatus (1) comprising: - a dressing tool holder (6) arranged for accommodating a dressing tool (4) in a dressing position, - a controllable actuator (7) for adjusting the position of the tool holder (6) within the apparatus (1) in at least one direction (x), - a grinding wheel support (14) for rotatably supporting a grinding wheel (2) to be dressed, the apparatus (1) further comprises means (13, 9) for monitoring an individual structure (12), created by the dressing tool (4) on the surface of the grinding wheel (2), and means (8) for monitoring a circumferential position and/or the rotary speed (19) of the grinding wheel (2), and means (10) for controlling the actuator (7), adapted to control the actuator (7) as a function of the monitored structure (12) and the monitored circumferential position and/or rotary speed (19).
(FR) La présente invention concerne un appareil (1) permettant de dresser une meule (2) montée sur celui-ci en créant des structures (12) à la surface d'une surface de meulage (3), en particulier cylindrique, de la meule (2), l'appareil (1) comprenant : - un porte-outil de dressage (6) conçu pour recevoir un outil de dressage (4) dans une position de dressage, - un actionneur commandable (7) permettant de régler la position du porte-outil (6) à l'intérieur de l'appareil (1) dans au moins une direction (x), - un support (14) de meule permettant de supporter en rotation une meule (2) destinée à être dressée, l'appareil (1) comprenant en outre des moyens (13, 9) permettant de surveiller une structure individuelle (12), créée par l'outil de dressage (4) à la surface de la meule (2), et un moyen (8) permettant de surveiller une position circonférentielle et/ou la vitesse de rotation (19) de la meule (2), et un moyen (10) permettant de commander l'actionneur (7), conçu pour commander l'actionneur (7) en fonction de la structure surveillée (12) et de la position circonférentielle surveillée et/ou de la vitesse de rotation (19) surveillée.
