Abstract

The invention discloses a resin grinding wheel for steel rail cutting and a manufacturing method of the resin grinding wheel, and relates to the technical field of grinding wheel manufacturing and production. The formula includes the following components of, in parts by weight, 7 - 9 parts of monocrystalline fused alumina, 7 - 9 parts of fused zirconia alumina, 3.8 - 4.2 parts of silicon carbide,2.8 - 3.2 parts of a binding agent and 0.8 - 1.2 parts of potassium sulfate, wherein the binding agent comprises phenolic resin powder and phenolic resin liquid, and the weight part ratio of the phenolic resin powder to the phenolic resin liquid is 2 : 1 - 3 : 1. The manufacturing method of the resin grinding wheel for steel rail cutting comprises a material mixing process and a forming process, wherein the material mixing process comprises the following steps of A1, mixing and preparing a pre-mixing material; A2, mixing a coarse grinding material; and A3, screening the coarse grinding material; and the forming process comprises the following steps of B1, paving a forming material; B2, carrying out pressurizing and forming; and B3, carrying out drying and hardening. The resin grinding wheel for the steel rail cutting has the technical effects that the cutting efficiency is high, the resin grinding wheel is not easy to wear, so that the service life is long.
