The water pump 7 and the external cooling pump 8 are connected in sequence, and the water inlet end of the external cooling pump 8 is connected to the filter 9. The filter 9 is installed at the upper end of the external cooling water tank 6 to reduce the contact between the filter 9 and the impurities deposited at the bottom of the external cooling water tank 6, which can reduce the shielding of the filter 9 by the impurities, thereby improving the utilization rate of the filter 9;

The output end of the multi-stage centrifugal pump 4 is connected to the liquid cooler 3 through the outlet pipe 12. The coolant is further pressurized and filtered by the multi-stage centrifugal pump 4 to increase the flow rate of the water outlet of the slide shaft 11, thereby making it easier to blow off impurities adhering to the tool and the workpiece, so as to facilitate the processing of the workpiece.

[0023] In this embodiment: by adding coolant to the external cooling water tank 6, the cooling water in the external cooling water tank 6 is pumped into the high-pressure water tank 5 by the water pump 7, during which it passes through a layer of filtration to ensure that there are no excessive impurities in the coolant, and then it is pressurized and filtered by the multi-stage centrifugal pump 4, and transported to the liquid cooler 3 for cooling, and then transported to the rotary joint at the rear end of the machine tool slide 10 through the high-pressure pipe, and then enters the slide spindle 11 through the slide, realizing the high-pressure center water outlet of the spindle.
