At present, most machine tools are provided with a cutting fluid flushing system to cool down workpieces and tools so as to ensure the stability of the temperatures of the workpieces and the tools in the cutting process.

Because the lathe can produce a large amount of cuttings in the cutting process, cutting fluid can mix with other impurity such as cuttings and greasy dirt when washing the cooling, need earlier get rid of impurity when reuse. The chip removal mechanism of the automatic inclined numerical control machine tool disclosed in the Chinese patent application (application number: 201920788445.9) comprises a machine tool main body, wherein a pair of chip removal channels are arranged at the bottom of the machine tool main body, a chip removal mechanism is arranged in each chip removal channel, a separation box is arranged on the left side of the machine tool main body, a chip guide plate is arranged at the left end of each chip removal channel and extends into each separation box, a vibration plate is arranged in each separation box, a filter screen is arranged on each vibration plate, and a drain pipe is arranged at the bottom of each separation box. The chips are separated from the cutting fluid by the vibration mechanism, and the cutting fluid is discharged from the drain pipe. However, since many extremely small-sized cutting particles are generated during the cutting process, the particles easily pass through the filter screen directly and are discharged into the drain pipe together with the cutting fluid, so that the cutting fluid needs to be filtered again for use in the subsequent process, the structure is complex, and the efficiency is low.

The pendulum oil-water separator for the machine tool machining center, as disclosed in the chinese patent application (application No. 20172117798.2), includes a liquid storage tank, a liquid inlet pipe connected to the bottom of the liquid storage tank, a liquid inlet squirrel cage connected to the liquid inlet squirrel cage, a stirring motor connected to the liquid inlet squirrel cage, a liquid outlet port of the liquid inlet pipe extending into the liquid inlet squirrel cage, a float seat disposed in the liquid storage tank, and an oil suction plate provided on the float seat and capable of swinging under the driving of the separation motor. However, the squirrel cage in the structure is continuously subjected to cutting along with the continuous filtering, so that the filtering efficiency is influenced, the squirrel cage needs to be frequently cleaned, the operation is extremely complicated, the working efficiency is low, and when the cutting fluid is filtered by the scheme, the stirring motor and the separation motor are required to continuously work, so that the energy consumption is high.
