Abstract

L'invention concerne un disque de ponçage (10, 110, 210) pour une machine de ponçage (90). Le disque de ponçage comporte un côté machine (11) associé à la machine de ponçage (90) et une face de travail (12, 112, 212) associée au ponçage d'une pièce (V). Du côté machine (11), il est prévu un support de raccordement d'outil (15) destiné à être fixé à un élément de raccordement d'outil (92) de la machine de ponçage (90) et sur la face de travail (12, 112, 212), il est prévu un moyen de ponçage (50) destiné à poncer une pièce (V) ou des moyens de retenue (33) destinés à maintenir de façon amovible un tel moyen de ponçage (50). Selon l'invention, la face de travail (12, 112, 212) du disque de ponçage (10, 110, 210) comporte une zone de bord annulaire (44, 144, 244) destinée à former une surface d'appui plane du moyen de ponçage (50) sur la pièce (V) et une zone centrale (45, 145, 245) entourée par la zone de bord annulaire (44, 144, 244). La zone de bord annulaire (44, 144, 244) fait saillie, par rapport à la zone centrale (45, 145, 245), en direction de la pièce (V) et/ou le disque de ponçage (10, 110, 210) comporte un module de compression plus faible dans la zone centrale (45, 145, 245) que dans la zone de bord (44, 144, 244) de sorte que lorsqu'une pression (P) agissant sur le support de raccordement d'outil (15) est appliquée en direction de la face de travail (12, 112, 212), la zone de bord (44, 144, 244) est sensiblement contrainte en direction de la pièce (V), ou est en contact avec la pièce (V), pour traiter la pièce (V) par abrasion.
