Abstract

The present invention provides an abrasive article formed of a binder, abrasive particles associated with the binder, and a lubricating particulate additive comprising polytetrafluoroethylene associated with the binder. The abrasive article of the invention is useful in the polishing of fiber optic connectors (13a) because the lubricating particulate additive allows the polishing rate of the softer glass fiber material (19, 22) to be slower than the polishing rate of the harder ceramic ferrule material (25). Methods of manufacture and methods of polishing a fiber optic connector (25) are also provided.
