[0023] The implementation principle of the coolant circulation structure of a CNC machine tool in an embodiment of the present application is as follows: the used coolant flows into the filter chamber 1 from the liquid inlet hopper 2, and the flowing coolant is doubly filtered by two filter plates 3 so as to efficiently remove impurities and debris contained in the coolant, thereby improving the purity of the coolant. Then, the coolant that has completed the filtration treatment flows out from the liquid outlet pipe 4, and when flowing through the cooling tube 5, it is subjected to the cooling treatment of the semiconductor condenser 9, so that the temperature of the used coolant is reduced, which is convenient for effectively cooling the workpiece to be processed next time. Then, the coolant that has completed the filtration and cooling treatment can be transported to the workpiece to be processed through the circulation pipe 7 under the action of the water pump 6, and the workpiece is cooled again, thereby realizing the recycling of the coolant and improving the utilization efficiency of the coolant.
