Abstract

A resin and rubber combined binding agent grinding wheel for polishing of ceramic materials comprises a grinding wheel base body and a grinding material layer stuck to the outer side of the base body; the base body is a bakelite base body; the grinding material layer is formed by mixing combined binding agents and grinding materials; the combined binding agents are composed of polyvinyl butyral resin, natural rubber, vulcanizing agents, vulcanization accelerators and vulcanizing activators; the grinding materials are composed of diamond and silicon carbide; the grinding material layer is composed of, by volume percentage, 15-40 parts of the polyvinyl butyral resin, 10-20 parts of the natural rubber, 2-6 parts of the vulcanizing agents, 3-6 parts of the vulcanization accelerators, 1-4 parts of the vulcanizing activators, 18-40 parts of diamond micro powder and 10-20 parts of silicon carbide micro powder. The prepared grinding wheel can meet the machining requirements for high precision and high surface quality of the fine ceramic materials.

Description

technical field [0001] The invention belongs to the field of superhard materials and products in mechanical processing, and in particular relates to a resin-rubber composite bond diamond abrasive grinding wheel for polishing precision ceramic materials and a preparation method. Background technique [0002] With the development of the electronics industry, especially the rapid development of high-precision processing industries such as electronic communications, LED, flat glass, and sapphire, the polishing process of finely ground ceramic materials is becoming more and more widely used. It specifically involves the polishing of sapphire wafers, blue glass polishing, silicon carbide seals, zirconia and other precision ceramic materials. Such workpieces require extremely high machining accuracy and surface quality. Through the corresponding high-precision, highly automated grinding equipment, advanced grinding technology matching the processing materials, and the corresponding...
