This has a problem that the machine tool inevitably generates a large amount of heat during machining at such a high rotational speed, and the heat of the high-temperature chips adheres to the surface of the machine tool table or the workpiece, which adversely affects the final machining accuracy of the workpiece and the operation of the machine tool. A large number of practices prove that the temperature of the workpiece changes by 1 degree during processing and changes by several microns within 1 meter, and the temperature of scrap iron generated during high-speed cutting on a processing center reaches several hundred degrees. In order to avoid the influence of the high-temperature iron chips falling on the surface of the workpiece on the local deformation of the workpiece, the iron chips need to be rapidly cooled. The common cooling methods include oil cooling, water cooling, air cooling, etc., and the cooling requirements are different according to the type, material and mode of the processed workpiece, and the advantages and the disadvantages of each cooling method are different. However, the single cooling system in the market cannot meet the diversification of the processing work, and if a plurality of cooling system devices are purchased, additional cost investment is caused.
