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.
