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.
La présente invention concerne un article abrasif constitué d'un liant, de particules abrasives associées au liant, et d'un additif particulaire de lubrification contenant du polytétrafluoroéthylène associé au liant. L'article abrasif selon l'invention peut être employé pour le polissage de connecteurs de fibres optiques étant donné que l'additif particulaire de lubrification permet de polir le matériau plus doux des fibres de verre à une vitesse inférieure par rapport à la vitesse de polissage du matériau plus dur de la ferrule céramique. La présente invention concerne également des procédés de fabrication et de polissage d'un connecteur de fibres optiques.
