The Use and Maintenance of CNC Cutting Fluid for Aluminum Alloy Machining
The formula and use of aluminum alloy CNC machining cutting fluid are basically the same as ordinary cutting fluid, but the selection of dilution water is more strict. Because many aluminum ions in water can cause corrosion, if the content of these ions is too high, it will reduce the rust prevention performance of the cutting fluid, especially in the process of rusting, such as chloride ions, sulfate ions, and heavy metal ions. In addition, certain ions can also react with the rust inhibitor of aluminum cutting fluid, reducing the rust resistance and stability of the cutting fluid, such as the occurrence of calcium and magnesium ions. So try to choose diluted water with lower hardness or softened ion exchange water after dilution to ensure the effectiveness and lifespan of the cutting fluid.

In addition to daily maintenance of cutting fluid, the maintenance of aluminum alloy CNC machining cutting fluid also needs to pay attention to the following points:
- Filtering
Due to the stability of aluminum alloy aluminum soap reaction, the cutting fluid is prone to damage under alkaline conditions. Aluminum chips, aluminum chips, and cutting fluid should be immediately filtered out to avoid further reactions that may affect the effectiveness and lifespan of the cutting fluid. The aluminum chips produced during the grinding process are small and light, making it difficult to continue settling. If they are not filtered or insufficiently filtered, the aluminum chip processing area will be carried away with the cutting fluid circulation system, and the surface will be scratched, affecting the glossiness of the processing surface.
- PH value
Due to the high sensitivity of aluminum cutting fluid to pH value, the pH value of aluminum cutting fluid should be regularly tested, and any abnormalities should be adjusted in a timely manner. Use a pH control between 8-9 to prevent excessive corrosion or low pH of the workpiece, which can cause bacterial growth and affect the stability and performance of the cutting fluid.
- Add new plans on a regular basis
Not only does it ensure good lubrication of the cutting fluid, but it also ensures good rust and corrosion resistance, extending the service life of the cutting fluid.
conclusion
The selection of CNC cutting fluid for aluminum alloy machining is extremely important. It is necessary to ensure good lubrication and corrosion resistance of the cutting fluid, as well as good stability, filtration, and easy maintenance. Only in this way can the requirements of the processed product be met and the cutting cost be minimized.
