Abstract

The invention discloses a high-speed cutting resin grinding wheel. The high-speed cutting resin grinding wheel comprises, by weight, 410-500 parts of CBN abrasive, 70-100 parts of white corundum powder, 96-110 parts of 34-40% of formaldehyde solution, 5-7 parts of boric acid, 2-6 parts of hexamethylene tetramine, 13-20 parts of aniline, 2-3 parts of potassium oxide, 90-100 parts of phenol, 3.6-4 parts of sodium fluosilicate and 0.6-1 part of pentaerythritol. The high-speed cutting resin grinding wheel is particularly suitable for high-speed cutting, and the grinding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a high-speed cutting resin grinding wheel and a preparation method thereof. Background technique [0002] With the continuous improvement of the speed of automobiles and airplanes, the requirements for friction materials such as transmission and braking are more stringent, and the matrix, as an important part of friction materials, has always been the focus of development and research. Phenolic resin, epoxy resin, styrene-butadiene rubber and polytetrafluoroethylene can be used as the matrix of friction materials, but epoxy resin, styrene-butadiene rubber and polytetrafluoroethylene have poor wear resistance, heat resistance and Adhesive properties limit its application in friction materials. The advantages of phenolic resin in heat resistance, bonding performance, mechanical properties, molding performance and cost make it the most commonly used binder matrix material f...
