The use of cutting fluid is essential to improve the processing efficiency and workpiece surface quality. However, the traditional cutting fluid recycling and spraying system still has many problems in practical application, resulting in the quality of finished product being low.

[0003] In the spraying process of traditional cutting fluid circulation system, metal chips are often brought back to the cutting surface. These metal chips will mix with fresh cutting fluid in the recycling and spraying of cutting fluid, forming a kind of turbid liquid. This not only affects the cooling performance of cutting fluid, but also may scratch the surface of metal workpiece during spraying, affecting the smoothness and accuracy of workpiece, and further causing a series of problems in subsequent processing or assembly.

[0004] Traditional cooling relies on cutting fluid to contact with air in the recovery tank to achieve cooling. This practice will cause water evaporation, and the concentration needs to be controlled frequently, thereby affecting production efficiency. Moreover, the volatile components of evaporated cutting fluid existing in the air may cause harm to workers' breathing and lungs, posing a hidden danger to the health of operating personnel.

[0005] In addition, cutting fluid is easily oxidized and deteriorated during the recycling process, reducing its lubricating performance and cooling capacity. This deteriorated cutting fluid will further affect the stability and safety of the machining process when sprayed onto the machining surface, increasing the risk in the production process.
