[0002] During the operation of CNC machine tools, coolant plays a vital role. It can not only effectively reduce the temperature of the cutting area and prevent the machine tool and workpiece from deformation or damage due to high temperature, but also provide necessary lubrication, reduce the friction between the tool and the workpiece, and extend the service life of the tool. In addition, the coolant can also take away the chips generated during the cutting process and keep the processing area clean, thereby ensuring the processing accuracy and surface quality. Through these multiple functions, the coolant not only ensures the normal operation of the machine tool, but also significantly improves the production efficiency and processing quality.
