[0002] CNC is the abbreviation of digital control. CNC technology is a method of controlling mechanical movement and processing using digital information. The early CNC system was composed of hardware circuits and was called hardware CNC. Nowadays, hardware circuit components are gradually replaced by dedicated computers and are called computer numerical control systems. CNC machine tools are part of the application of CNC systems.

[0003] A Chinese patent with publication number CN215147341U was searched and disclosed a cooling device for high-precision CNC machine tools.

[0004] The above technical solution includes: a liquid storage tank, a liquid inlet pipe is provided on the upper surface of the liquid storage tank, a cold liquid chamber is provided just below the liquid inlet pipe and inside the liquid storage tank, a liquid spray pipe is fixedly connected to the lower surface of the cold liquid chamber, a control valve is fixedly connected to the upper end of the liquid spray pipe, a circulation pipe is provided on the upper surface of the liquid storage tank, a circulation chamber is provided just below the circulation pipe and inside the liquid storage tank, a circulation nozzle is fixedly connected to the lower surface of the circulation chamber, a control valve is fixedly connected to the upper end of the circulation nozzle, a circulation hose is fixedly connected to the upper end of the circulation pipe, and a liquid outlet pipe is fixedly connected to the other end of the circulation hose. In the utility model, by providing a liquid storage tank and a recovery tank, the recycling of coolant can be achieved, resources can be saved, and costs can be reduced;

[0005] However, in the above scheme, although this technology can cool the workpiece during machine tool processing, the contact area and contact pressure during processing cause the temperature of the workpiece to change accordingly. This technology cannot realize dynamic cooling, and there will be untimely cooling or waste of coolant. Although this technology can recycle the coolant, the fine debris contained in the coolant cannot be completely filtered, which will cause equipment damage. The machine tool is usually set in a flat surface, and a part of the debris will not flow with the coolant, and will be deposited on the machine tool, affecting the appearance.

[0006] To this end, we propose a cooling device for CNC machine tools. Utility Model Content
