Abstract

The invention relates to a grinding wheel applied to a zirconia ceramic ferrule PC spherical surface. The grinding wheel comprises a grinding wheel base body and a grinding layer, wherein the grindinglayer is mainly composed of an abrasive material, a resin binder and stuffing; the stuffing is made of polytetrafluoroethylene, high-density polyethylene and an active nano-polishing agent; the active nano-polishing agent is composed of the following raw materials of, by weight, 10%-30% of cerium oxide, 5%-15% of ferric oxide, 25%-40% of chromium dioxide and 20%-40% of flake graphite. The grinding wheel belongs to superfine powder grinding wheels, the requirements for curvature radius and high-surface quality of the ferrule PC spherical surface can be met, the grinding wheel is sharp, the shape retention property is good, the processing efficiency is high, and the no-dressing situation can be achieved during grinding.

Description

technical field [0001] The invention belongs to the technical field of superhard materials and products in mechanical processing, and in particular relates to a grinding wheel applied to a PC spherical surface of a zirconia ceramic ferrule and a preparation method thereof. Background technique [0002] Ceramic ferrule is a kind of optical fiber ferrule, which is made of nano-zirconia (ZrO 2 ) is a cylindrical precision ceramic device made through a series of complex sintering processes. It has a hard texture, high melting point, wear resistance, and good thermal stability. It is the most commonly used and the largest number of precision positioning parts in optical fiber communication networks. Manufacture of fiber optic connectors, optical coupling of devices, etc. The main function of the ceramic ferrule is to realize the physical connection of the optical fiber, and it is often used in conjunction with the ceramic sleeve. [0003] Ceramic ferrule has high strength and h...
