Title (EN) AN ABRASIVE ARTICLE HAVING A BACKING, SUITABLE FOR ATTACHMENT TO A ROTATABLE SHAFT, AND PREPARATION THEREOF
(FR) ARTICLE ABRASIF DOTÉ D'UNE SURFACE DE SUPPORT, ADAPTÉE POUR LA FIXATION À UN AXE ROTATIF, ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract: front page image
(EN)A method is described for making an abrasive article comprising an abrasive part (1) and a backing (2) fixed to the abrasive part to provide for attachment of the abrasive article at a central location (3) to a rotatable shaft of a driven tool, wherein the abrasive part (1) comprises a substrate having abrasive characteristics. The method comprises placing a restricting layer (6) adjacent the abrasive part (1), injecting molten polymeric material onto the restricting layer, the restricting layer causing the polymeric material to spread over the abrasive part, and allowing the polymeric material to cool while remaining in contact with the abrasive part to form the backing (2).
(FR)L'invention concerne un procédé de fabrication d'un article abrasif qui comprend une partie abrasive (1) à laquelle est assujettie une surface de support (2) destinée à assurer la fixation de l'article abrasif, dans un emplacement central (3), à un axe rotatif d'un outil entraîné. La partie abrasive (1) comporte un substrat doté de caractéristiques abrasives. Le procédé consiste à: placer une couche restrictive (6) à proximité de la partie abrasive (1); injecter un polymère fondu sur la couche restrictive, cette dernière amenant le polymère à s'étaler sur la partie abrasive; et laisser refroidir le polymère en contact avec la partie abrasive pour former la surface de support (2).
