Abstract

The invention discloses a large-diameter high-speed cutting and high-speed heavy load grinding resin wheel prepared from the following three components in percentage by weight: 60-72 percent of grinding materials, 18-25 percent of filling materials and 8-18 percent of resin, wherein the grinding materials in the wheel are film-coating calcined brown fused alumina, the filling materials comprise aheat conducting material and an active filling material, and the resin comprises a phenolic resin liquid and phenolic resin powder. The sand is produced by adopting the film-coating calcined brown fused alumina, which has good heat conduction property of metal plating, obviously strengthens the heat radiating effect of the wheel and prolongs the abrasive resistance and the service life of the wheel. In addition, the grinding materials have improved ball-milling flexibility after calcined, which enables the wheel to be durable and the property to be better. The wheel can be used for cutting hot-wire type steel with a diameter of over 100 mm or grinding the steel in a high-speed and heavy load way, and has long service life reaching 100-120min.

Description

technical field [0001] The invention relates to a cutting and grinding grinding wheel for machining, in particular to a resin grinding wheel for large-diameter high-speed cutting and high-speed heavy-load grinding. Background technique [0002] Large-diameter high-speed cutting resin grinding wheel refers to a glass fiber mesh reinforced resin cutting wheel with a diameter between Φ1000mm~Φ1800mm, a thickness of 10mm~16mm, and a working speed of 80m / s~120m / s. heat resistance. This grinding wheel is mainly used for the cutting of fixed-length linear materials produced by iron and steel enterprises. When cutting, the temperature of the steel is between 400°C and 600°C, and the cutting speed V is greater than or equal to 100m / s. Under such working conditions, the cutting grinding wheel should have the characteristics of high strength, good heat resistance, sharp cutting, good heat conduction and heat dissipation, and high durability of the grinding wheel. [0003] At present,...
