  • Patent number: 6354929
    Abstract: The present invention is a fixed abrasive article for grinding or polishing the surface of a glass workpiece. The abrasive article for grinding glass has abrasive composites containing a binder, an alkaline metal salt, and diamond abrasive particles or agglomerate particles comprising diamond particles, the composites integrally molded to a backing. The abrasive article for grinding glass is capable of removing between about 200 and 400 micrometers of glass using an RPP procedure having a polish time interval of between 10 and 15 seconds, generally about 12 seconds. The abrasive article for polishing glass comprises a backing containing fibers, and a plurality of abrasive composites integrally molded to the backing comprising an organic resin, ceria abrasive particles, and alkaline metal salt. The abrasive articles for polishing glass also provide an optimum rate of breakdown of the abrasive composites and improved adhesion between the abrasive composites and the backing.
