The invention describes an abrasive system comprising a fiber-backed abrasive disc (1) and a backup pad (11) in which the backup pad (11) has spaced portions (12) removed from the circumference such that the disc (1) overlaps in the area of the removed portions (12). This has the effect of inhibiting catching of the disc on obstructions and enabling easy swarf removal during operation.
L'invention concerne un système d'abrasion, comprenant un disque abrasif (1) renforcé de fibres et un tampon d'appoint (11), ce dernier comportant des parties espacées (12) retirées de sa circonférence de façon que le disque (1) se superpose à l'emplacement des parties retirées (12), ce qui a pour effet d'empêcher tout accrochage du disque lors d'obstacles et de permettre une élimination facile des copeaux en cours d'utilisation.
