A vitrified bond composite parallel grinding wheel for double-end surface grinding

Abstract

The invention discloses a ceramic bond composite parallel grinding wheel for double end surface grinding. The ceramic bond composite parallel grinding wheel comprises a grinding material layer and a base layer, wherein the lower surface of the grinding material layer is bonded with the upper surface of the base layer, the diameter of the grinding material layer is equal to the diameter of the base layer, the grinding material layer is an oxide series or carbide series ceramic bond grinding block, the base layer is a resin bond grinding block, or an aluminum alloy plate or a bakelite plate, and an annular stress groove and a plurality of radial stress grooves are formed in the grinding material layer. The composite parallel grinding wheel is formed by fully utilizing and reasonably combining the respective advantages of a ceramic grinding wheel and a resin grinding wheel, and at the same time, stress suffered by the grinding material layer is fully released by forming the annular stress groove and the plurality of radial stress grooves in the grinding material layer. Therefore, one ceramic bond composite parallel grinding wheel which is large in load capacity, sharply grinds, is pollution-free and is suitable for being mounted on the existing double end surface grinding machine is realized.

Description

technical field [0001] The invention belongs to the technical field of double-end grinding machines, and in particular relates to a vitrified bond composite parallel grinding wheel for double-end grinding. Background technique [0002] The double-end grinding machine is the key equipment for processing piston rings and bearings. It is used for rough machining and finishing machining of piston rings or bearings. Its quality is directly related to the precision and qualification rate of piston rings or bearing grinding. Currently, piston rings or bearings are The grinding wheel used in the double-end grinding machine is limited by the connection method with the grinding machine and the conditions of heavy load, so the resin grinding wheel is generally used. The resin grinding wheel has the advantage of heavy load, but it is easily limited by the grinding fluid, the grinding performance of the grinding wheel is prone to change and instability during the grinding process, and it...
