Title (EN) SELF-CONTAINED CONDITIONING ABRASIVE ARTICLE
(FR) ARTICLE ABRASIF DE TRAITEMENT INDÉPENDANT
Abstract: front page image
(EN)Provided is a fixed abrasive article for polishing a workpiece having a hardness comprising (a) a substrate having a first surface and a second surface, (b) a region of abrasive composites distributed on the first surface of the substrate, and (c) a region of conditioning amalgams distributed on the first surface of the substrate. The abrasive composites include a composite binder and abrasive particles of a first hardness, which first hardness is higher than the hardness of the workpiece. The amalgams include an erodible binder and conditioning particles sufficient to condition the composite binder and having a second hardness, which second hardness is less than the hardness of the workpiece and greater than the hardness of the composite binder. Also provided are other abrasive articles, and methods of making them.
(FR)La présente invention concerne un article abrasif fixe destiné à polir une pièce à travailler ayant une dureté, comprenant (a) un substrat doté d’une première surface et d’une seconde surface, (b) une région de composites abrasifs répartis sur la première surface du substrat, et (c) une région d’amalgames de traitement répartis sur la première surface du substrat. Les composites abrasifs comprennent un liant composite et des particules abrasives présentant une première dureté, laquelle est plus importante que celle d’une pièce à travailler. Les amalgames comprennent un liant érodable et des particules de conditionnement suffisants pour traiter le liant composite et présentant une seconde dureté, laquelle est moins importante que celle de la pièce à travailler et plus importante que celle du liant composite. L’invention concerne également d’autres articles abrasifs et des procédés pour les fabriquer.
