[0015] (2) An ultra-precision filtering high-pressure constant temperature device for machine tools, which, when in use, drives the coolant inside the copper tube to circulate through the first pump body, thereby facilitating the coolant to dissipate heat through the cooling fan and fins. The cooled coolant will cool down the cutting fluid inside the water tank, thereby cooling the high-temperature cutting fluid and maintaining a constant temperature.

[0016] (3) An ultra-precision filtering high-pressure constant temperature device for machine tools, wherein the degreased cutting fluid enters the water inlet through one end of the water tank, and then enters the filter screen. The cutting fluid can filter the metal impurity particles in the cutting fluid when passing through the filter screen. Then, when the cutting fluid is outside the circulation belt, under the action of the electromagnet, the fine metal impurities remaining in the cutting fluid can be adsorbed to the inner wall of the shell close to the electromagnet side, which is conducive to achieving high-precision filtration. The cutting fluid that has been filtered with high precision enters the booster pump through the lifting pipe and is then output through the other end of the booster pump, so that the cutting fluid of the machine tool can be recycled.
[0017] (4) An ultra-precision filtration high-pressure constant temperature device for machine tools. After the cutting fluid initially enters the surface of the water inlet trough, it will flow to the inside of the sieve drum through the slope of the guide trough, and then be filtered through the holes on the surface of the sieve drum. The cutting fluid filtered by the sieve drum can flow into the cavity below the sieve drum, and then the cutting fluid passing through the cavity can enter the water tank through the connecting port, and can drive the auger inside the sieve drum to rotate under the drive of the second motor, and then the auger can drive the impurities inside the sieve drum to move, so that the impurities inside the sieve drum can gather at one end of the sieve drum, and then block the impurities at one end of the sieve drum. When the impurities accumulate too much, the sealing plate will be pushed open, and then automatically discharged from one end of the sieve drum. Then, under the push of the spring, when the impurities at one end of the sieve drum are discharged, the sealing plate can be closed again with the one end of the sieve drum, so that there is no need to manually clean the sieve drum, which is conducive to improving the convenience of using the device.
