Description

Technical Field

[0001] The present application belongs to the technical field of numerical control machining and relates to an oil-water separation system for a numerical control machining center. Background Art

[0002] The machining center is a high-efficiency automated machine tool composed of mechanical equipment and CNC systems suitable for machining complex parts. When machining workpieces, the machining center will spray water or cutting fluid on the workpiece to cool and protect the workpiece. In addition, due to the need for lubrication, there will be oil stains on the machining equipment and workpieces. Therefore, an oil-water mixture will be produced during the machining process. Among them, after the oil and water dirt are initially filtered out using a filter to filter out large impurities during the machining process, they will flow into the liquid storage tank. Due to the different specific gravities of oil and water, the oil will float on the water (cutting fluid). The machining center will directly reuse the separated cutting fluid. Since the amount of oil is relatively small, the oil stains will be cleaned up when the equipment is maintained.

[0003] Patent CN204469371U discloses an oil-water separation device for cutting fluid and waste oil of CNC machine tools, the device includes a liquid-chip box, an oil-water separation box and a water tank, wherein the liquid-chip box is located above the water tank, the oil-water separation box is sunk into the water tank, and the mouth of the oil-water separation box is located below the water outlet of the liquid-chip box; the water outlet of the liquid-chip box faces the oil-water separation box, and the drain port of the oil-water separation box faces the water tank. The liquid-chip box on the water tank at the rear of the machine tool is used to filter and separate the oil-water mixture from the processed iron chips, and then the mixture is separated from the oil-water mixture before entering the water tank through the mixed liquid tank, cutting fluid tank and oil receiving tank of the oil-water separation box.
