When the tool body temperature drops, the sliding door automatically closes, thus stopping the supply of coolant. This can quickly remove heat, reduce the cutting temperature, prevent the cutting edge material from softening due to high temperatures, and maintain its original hardness. This prevents the tool from failing, deforming, or breaking due to overheating. At the same time, it can reduce friction between the workpiece and the tool body, reduce the tool wear rate, extend its service life, and maintain the hardness of the tool edge, keeping it sharp and improving cutting efficiency. Stopping the supply of coolant after the tool temperature drops can save coolant usage, conserve resources, and be more environmentally friendly.

[0024] 2. By setting up a grinding and anti-rolling mechanism, the motor drives the grinding roller to rotate. When the tool body moves to the grinding roller, it is ground.
