An abrasive article (10) made from a plurality of abrasive composites (20) bonded to form a three dimensional abrasive article. Each abrasive composite (20) includes a plurality of primary abrasive particles (30) bonded together by a first binder matrix (34) to form a shaped or irregular abrasive composite. Present within the abrasive composite (20) is an intra-composite porosity between and among the primary abrasive particles. Inter-composite porosity is present within the abrasive article (10) between and among the abrasive composites (20). The abrasive article (10) is used to grind glass and other workpiece surfaces to a mirror finish.
Cette invention se rapporte à un article abrasif (10) fabriqué à partir de plusieurs composites abrasifs (20) agglomérés de façon à former un article abrasif tridimensionnel. Chaque composite abrasif (20) contient plusieurs particules abrasives primaires (30) agglomérées par une première matrice de liant (34), afin de former un composite abrasif façonné ou irrégulier. Dans le composite abrasif (20) est présente une porosité intra-composite entre et parmi les particules abrasives primaires. Une porosité inter-composite est présente dans l'article abrasif (10) entre et parmi les composites abrasifs (20). Cet article abrasif (10) est utilisé pour meuler du verre et d'autres surfaces de pièces travaillées pour leur conférer un fini miroir.
