Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and particularly relates to an oil-water separation cutting fluid circulation tank. Background Art

[0002] In the process of machining, in order to take away the heat generated by cutting, cutting fluid is usually used. The cutting fluid is used to reduce the temperature of the workpiece and the tool, reduce the thermal deformation and thermal damage during the cutting process. The cutting fluid can also improve the machining efficiency and machining quality. A large amount of chips are mixed in the cutting fluid during use. If there are chips in the cutting fluid, it will affect the performance of the cutting fluid, machining efficiency and machining quality. Therefore, it is necessary to filter the chips in the cutting fluid. On the other hand, during the use of the machine tool, the cutting fluid is prone to produce oil stains, including: lubricating oil on the machine tool guide rail, hydraulic oil leaked in the hydraulic system, oil stains brought in by the workpiece, and oil stains generated by the demulsification of the cutting fluid. If a large amount of oil stains are mixed in the cutting fluid, it will lead to a decline in the performance of the cutting fluid, contaminate the surface of the workpiece, affect the surface quality of the workpiece, accelerate the deterioration of the cutting fluid, reduce the service life of the cutting fluid, and increase the use cost of the cutting fluid.

[0003] Therefore, the above problems need to be solved urgently. Content of the Utility Model
