  • Publication number: 20220305620
    Abstract: A tool-cooling mechanism includes a grinding tool. The grinding tool is provided with a converging disc, and the converging disc rotates with the grinding tool to draw external cooling water into the grinding tool for convergence, and then radially conveys the cooling water as converged toward an inner wall of the grinding tool, such that the cooling water can flow to a grinding surface along the inner wall of the grinding tool. The cooling water is allowed to enter via a water inlet and cool the grinding surface smoothly even when the grinding tool is rotating at a high speed, such that the cooling water can be prevented from passing through the grinding tool axially and failing to cool the grinding surface. In addition, the grinding surface is cooled after the cooling water as dispersed and atomized by the rotation of the grinding tool is converged.
