Abstract

The invention belongs to the field of abrasive wheels, and in particular relates to a fiber-reinforced resin heat-resistant high-speed abrasive cutting wheel with a large diameter and a flake structure and a processing method thereof. In the invention, the abrasive wheel is divided into a center reinforced part and a cutting part which adopt different formulas, wherein the formula of the center reinforced part has the advantages of high strength and good cohesiveness with a fiber glass reinforced net, and because the center reinforced part does not use zirconia alumina and other materials with a relatively higher price, the cost is saved. By adding iron sulfide powder, cryolite powder and titanium dioxide fine powder to the cutting part, and optimizing the respective proportion, the heat resistance and wear resistance of the cutting part are enhanced and the cutting ratio is improved. The abrasive wheel of the invention has the advantages of good heat-resistant property, good wear-resistant property, high cutting ratio and low cost.

Description

technical field [0001] The invention belongs to the field of grinding wheels, and in particular relates to a fiber-reinforced resin heat-resistant high-speed cutting grinding wheel with a large diameter and a sheet structure and a processing method thereof. Background technique [0002] Fiber-reinforced resin grinding wheel is a type of grinding wheel that uses phenolic resin as a binder for cutting and rough grinding. It has the advantages of high strength, not easy to break, and high removal rate. However, when cutting the shaped round steel, square steel and other steel products just out of the smelting furnace, the cutting wheel with large diameter and thin slice structure is prone to defects such as poor high temperature resistance, high consumption of the grinding wheel and small cutting ratio due to the high temperature of the steel. Even cause the fragmentation of emery wheel, have had a strong impact on the application of resin cutting emery wheel in hot-rolled ste...
