[0018] The specific implementation of this utility model is further described in conjunction with the drawings and embodiments.

[0019] A cutting fluid supply system for a numerical control machining center, comprising: a cutting fluid replenishment system, a sedimentation water tank 1, a machine tool fluid supply system, a cooling system, a filtering system, a recoil system, and a control system 21. The cutting fluid replenishment system comprises a raw material barrel 8 and a raw liquid tank 9. The raw material barrel 8 is connected to the liquid inlet of the raw liquid tank 9 through a pipeline and a pneumatic diaphragm pump 10. A liquid level alarm 19 is provided in the raw liquid tank 9. The liquid level alarm 19 is electrically connected to the control system 21. The liquid outlet is connected to the sedimentation water tank 1 through a proportional liquid dosing pump 11 and a liquid replenishment pipeline 12. The proportional liquid dosing pump 11 is connected to a tap water pipeline through a gate valve 22 and a solenoid valve 23. The sedimentation water tank 1 is provided with a liquid level alarm 19. An oil-water separator 18 is provided on one side of the sedimentation water tank 1. The sedimentation water tank 1 is provided with a cleaning window 6. A backwash pipeline 20 is provided at the bottom of the sedimentation water tank 1. The backwash pipeline 20 is divided into four branches respectively connected to the four backwash filter drums 4. The cooling system includes a water cooler 17 and a heat exchanger 16. The heat exchanger 16 is connected to the sedimentation water tank 1 through a water pump. The liquid outlet of the heat exchanger 16 is connected to the water cooler 17 through a pipeline. The liquid outlet of the water cooler 17 is connected to the sedimentation water tank 1 through a pipeline. The filtering system includes a recoil scraper chip conveyor 2 and a bag filter 7. Four recoil filter drums 4 are arranged in the recoil scraper chip conveyor. The recoil filter drum 4 is connected to the sedimentation water tank through a guide tube 5. 1, the recoil scraper chip conveyor 2 is fixed to the top of the sedimentation water tank 1 by screws, the sedimentation water tank 1 and the recoil scraper chip conveyor 2 are connected through a buffer tank 3, the machine tool fluid supply system includes a machine tool fluid supply pump 13, the liquid inlet of the machine tool fluid supply pump 13 is connected to a bag filter 7, the bag filter 7 is connected to the sedimentation water tank 1 through a pipeline, and the machine tool fluid supply pump 13 transports the mixed cutting fluid after cooling and filtration in the sedimentation water tank 1 to the machine tool fluid supply pipeline.

[0020] When a CNC machining center processes metal parts, in order to prevent the temperature from being too high during the machining process, it is necessary to supply cutting fluid to cool down during the machining process. The pneumatic diaphragm pump 10 draws the cutting stock in the stock liquid barrel into the stock liquid tank 9, and the liquid level is automatically controlled by the control system 21 through the sensing of the liquid level alarm 19 on the stock liquid tank 9. The proportional liquid pump 11 uses tap water as the power to continuously and evenly suck the cutting stock and tap water in the stock liquid tank 9 in a certain proportion and pump them into the replenishing pipeline 12, and transport them to the sedimentation water tank 1, and then supply cutting fluid to the CNC machining center through the machine tool liquid supply pump 13. At the same time, the cutting fluid used by the CNC machining center is first passed into the buffer tank 3 to buffer the pressure through the machine tool liquid supply pump 13, and then passed into the recoil scraper chip conveyor 2, and passed through the recoil filter drum provided in the recoil scraper chip conveyor 2. 4 After filtration, the liquid flows into the settling water tank 1 below through the guide tube 5. In order to save costs, the cooling system and the recoil system are combined in this embodiment. The cutting fluid in the settling water tank 1 is pumped into the heat exchanger 16 through the recoil pump 15. At the same time, the water cooler 17 and the heat exchanger 16 form a closed cycle through the pipeline. After the cutting fluid is cooled to a suitable temperature by the heat exchanger 16, it enters the recoil pipeline 20. The recoil pipeline 20 is divided into four branches to respectively wash the filter screens on the four recoil filter drums 4. In this way, the filter screen can be cleaned and the cutting fluid in the settling water tank 1 is cooled at the same time. At this time, the machine tool liquid supply pump 13 works to pump the mixed cutting fluid in the settling water tank 1 that has been cooled and filtered by the recoil filter drum 4 into the bag filter 7 for filtration. After filtration, it is supplied to the CNC machining center through the pipeline. The oil-water separator 18 can filter out the oily impurities in the settling water tank 1 in real time.
