Abstract

L'invention concerne un disque abrasif de meulage (18) constitué d'un support comprenant une zone périphérique en forme de couronne (4), une zone médiane de forme conique (6) et une zone centrale en forme de disque (8) , la zone périphérique (4) étant munie de segments abrasifs (20), des ouvertures permettant l'aspiration ou l'insufflation d'air étant prévues dans la zone périphérique (4). Les segments abrasifs (20) ont en substance une forme d'accent circonflexe, et présentent une aile (22) s'étendant sensiblement suivant le pourtour du disque (18), et une aile (24) s'étendant sensiblement du pourtour vers le centre du disque (18). De manière préférée, les segments abrasifs (20) ont la forme d'une aube, et le profil de cette aube est déterminé de telle sorte que, lorsque le disque (18) est en rotation, l'air aspiré ou insufflé s'écoule avec une vitesses absolue suivant les rayons du disque.

Figure 00000001
The invention relates to a grinding abrasive disc (18) consisting of a support comprising a peripheral zone in the form of a crown (4), a central zone of conical shape (6) and a central zone in the form of disc (8), the peripheral zone (4) being provided with abrasive segments (20), openings allowing the suction or the blowing of air being provided in the peripheral zone (4). The abrasive segments (20) essentially have a shape of a circumflex accent, and have a wing (22) extending substantially along the periphery of the disc (18), and a wing (24) extending substantially from the periphery towards the disc center (18). Preferably, the abrasive segments (20) have the shape of a blade, and the profile of this blade is determined so that, when the disc (18) is rotating, the air sucked or blown flows with an absolute speed along the spokes of the disc.
