Summary: | The present invention relates to a method and an article for rapidly polishing a glass workpiece surface using a structured abrasive article including cerium oxide particles dispersed in a binder. The abrasive article for rapid polishing of a glass workpiece comprising a backing and at least one polishing layer. The polishing layer comprises cerium oxide particles dispersed within a binder. The binder provides the attachment means of the at least one polishing layer to the backing. The abrasive article is capable of reducing an initial Rtm of about 0.8 mu m or greater on a glass test blank to a final Rtm of about 0.3 mu m or less in about one minute using an RPE procedure defined herein. The present invention is also directed to a method of polishing a glass workpiece using the present abrasive article. |
