[0028] In addition, the device ensures that the cooling liquid can be quickly and accurately sprayed to the cutting area, effectively reducing the cutting temperature and cutting resistance, improving the cutting efficiency, reducing the generation of heat and wear, thereby prolonging the service life of the cutting tool 14 and the cutting table 1; the waste generated during the cutting process can also flow smoothly into the drain pipe 20 through the flow-through hole 19 for centralized treatment, ensuring the cleanliness and efficiency of the entire cutting process.
