[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. Among them, cutting machine tool refers to a machine tool that uses cutting, grinding or special processing methods to process various mechanical workpieces, which can enable the workpiece to obtain the required geometric shape, dimensional accuracy and surface quality.

[0003] When cutting mechanical workpieces, the surface processing of the workpiece is mainly completed by the relative movement of the cutting tool and the workpiece. The friction between the tool and the workpiece will generate high temperature, which will increase the surface temperature of the tool. When it reaches a certain threshold, it will cause tool wear or even breakage. In addition, excessive temperature will lead to reduced cutting surface quality and changes in surface hardness, which will have an adverse effect on the workpiece. Therefore, cooling equipment is required to cool the cutting tool. Generally, the tool is cooled by spraying water with a nozzle. The sprayed water is not easy to collect and reuse, and it is easy to pollute the working area and cause waste of water resources. Utility Model Content
