Title
(EN) COATED ABRASIVE ARTICLES AND METHODS OF MAKING AND USING THE SAME
(FR) ARTICLES ABRASIFS REVÊTUS ET LEURS PROCÉDÉS DE RÉALISATION ET D'UTILISATION
Abstract
(EN) Coated abrasive articles comprises a backing having a major surface with an abrasive layer disposed thereon. The abrasive layer has an outer major surface comprising ridges separated by valleys, wherein the abrasive layer comprises magnetizable particles and abrasive particles in a binder. Each of the ridges is irregularly shaped and is oriented along at least a portion of its length substantially parallel to adjacent ridges. Methods of making the same involving a modulated magnetic field are also disclosed.
(FR) L'invention concerne des articles abrasifs revêtus, lesquels articles comprennent un revers ayant une surface principale avec une couche abrasive disposée sur celle-ci. La couche abrasive a une surface principale externe comprenant des crêtes séparées par des vallées, la couche abrasive comprenant des particules magnétisables et des particules abrasives dans un liant. Chacune des crêtes est de forme irrégulière et est orientée le long d'au moins une partie de sa longueur sensiblement parallèlement aux crêtes adjacentes. L'invention concerne également des procédés pour leur réalisation, mettant en œuvre un champ magnétique modulé.
