In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
