[0002] With the development of industry and technology within the industry, we have found that there is a great demand for light-colored and colored grinding wheels in the market. The phenolic resin currently used in resin grinding wheels generally uses urotropine as a curing agent to cure and color the grinding wheels. Generally, the post-curing temperature is high, which will cause the resin color to turn black-brown, and the phenol in the resin will also change due to hydroxyl oxidation. At present, light-colored resin grinding wheels are generally manufactured by lowering the post-curing temperature, but due to insufficient post-curing temperature, the grinding wheel itself will not be fully cured, the brittleness will increase, the grinding efficiency will be reduced, and the dust will increase. Now a light-colored and dust-free grinding wheel structure is needed.

The heat dissipation and chip removal effect of the existing grinding wheel structure during use is not good enough, which reduces the structural strength of the grinding wheel structure body and the abrasive layer when the grinding wheel structure is used, increases the possibility of breakage of the grinding wheel structure body and the abrasive layer during operation, and greatly shortens the service life of the grinding wheel structure; thirdly, the resin color of the grinding wheel structure turns black-brown when it is used, and more dust is generated.
