[0002] A lathe is a device that uses a turning tool to turn a rotating workpiece. When the lathe is processing the workpiece, in order to absorb the heat generated during the cutting process, reduce the temperature of the workpiece and the tool, and reduce the friction between the tool and the workpiece, it is necessary to spray cutting fluid on the workpiece.

[0003] After searching, the Chinese patent "A cutting fluid circulation device for CNC machine tools" authorization announcement number "CN215748138U" is found. When parts are processed, by starting the first water pump, the first water pump draws the cutting fluid in the storage chamber into the injection tube, which can cool and lubricate the processed parts. Then the used cutting fluid flows into the two filter cylinders through the two connecting pipes. The two filter cylinders can filter the debris in the cutting fluid. Then, through the sewer pipe, the filtered cutting fluid is discharged into the recovery box for storage for easy reuse.

[0004] Although the above application can filter the cutting fluid, during the filtration process, impurities in the cutting fluid will adhere to the surface of the filter cartridge.
