Embodiment 1

[0016] will A24 # 40 copies, A30 # 40 copies, A36 # 20 parts, 6.0 parts of liquid resin, 11.5 parts of powder resin, 5.0 parts of sulfur concentrate powder, 6.0 parts of cryolite, 5 parts of light calcium carbonate and 0.05 parts of carbon black. Mesh sieve for mixing, after mixing, pass through 8-mesh sieve to form the molding material, loosen the molding material through the sieve and put it into the mold, spread and scrape the material, add mesh and hole ring, put it into the press for pressing, The pressure is not less than 150Mpa, the temperature is 40-60°C, the mold is unloaded after holding the pressure for 30 seconds, and it is hardened in the furnace. The hardening curve is 10 hours and 8 hours, and the highest temperature is about 185°C.

Abstract

The invention relates to a resin-reinforcing high-speed grinding wheel. The invention is characterized in that each group comprises A24<#,, A30<#>, A36<#>, resin liquids, resin powders, sulfur concentrate powders, cryolites, light calcium carbonates and carbon blacks. After a qualified inspection to each group, the components are weighted according to the prescription and are mixed through a 80-mesh sieve, and the mixture is griddled through a 8-mesh sieve to become a finished material. Then the finished material is loosened through the sieve and then is put into a mould. After the material is spread and scraped, a web piece and a bore-ring are put into the mould, and then the mould is put into a pressing machine for pressing, with a pressure of no less than 150MPa and a temperature ranging from 40 to 60 degree centigrade. After the pressure is preserved for 30 seconds the mould is disassembled and the material is put into a furnace for hardening. After hardening, the qualified product is the eligible product. The invention, on a basis of not reducing the product safety and various technical indexes, makes use of the home common raw materials and selects an excellent prescription so as to reduce the product cost and enhance the market competition as much as possible. The invention is characterized in that the strength is high; crash can be avoided and the grinding effect is good.

Description

technical field [0001] The invention relates to an abrasive tool, in particular to a resin-reinforced high-speed grinding wheel, which belongs to the abrasive tool manufacturing technology. Background technique [0002] Resin-reinforced high-speed grinding wheels are a type of grinding wheels that use phenolic resin as a bond for rough grinding and cutting. The resin-reinforced high-speed grinding wheels in the domestic market are generally divided into high-grade and low-grade. High-end products generally use imported raw materials, such as resin and abrasives. The products produced have the advantages of high strength, unbreakable, wear-resistant, etc., but are expensive; low-end products generally use domestic common raw materials, and the cost is low, but the products have disadvantages such as low strength, fragility, and poor abrasiveness, and lack market competitiveness. There is an urgent need in the market to have a resin-reinforced high-speed grinding wheel that c...
