What cutting fluid can be used to process oxidized aluminum parts for CNC production?

The material in the aluminum alloy and the cutting fluid cause an oxidation reaction; the plasticity of the aluminum alloy is low, the melting point is also low, and the thermal conductivity is good. If the lubricity and cooling of the cutting fluid are not reached when processing the aluminum alloy, it will cause the aluminum alloy processing to appear. Tool sticking and chip removal performance is poor. In such a cycle, the tool is corroded and the probability of tool breakage is greatly improved. Secondly, when processing aluminum, it depends on the composition of magnesium and silicon inside. If the composition of magnesium is large, it is easy to analyze. Soap, the cutting fluid used for processing at this moment is easy to lose its lubricating effect, and it will also cause tool breakage. At the same time, aluminum alloy is a sensitive amphoteric metal, which easily forms a chemical reaction in the air, causing oxidation.

The cutting fluid corrodes the aluminum parts. The white spots are the lack of cleaning power of the cutting fluid, and there are cutting fluid residues on the surface of the parts. At the same time, the pH value of the cutting fluid is also very important. Too high a pH value will corrode the workpiece. If the pH value is too low, bacteria will multiply in large quantities and affect the stability and performance of the cutting fluid. Oxidized aluminum parts should be used: aluminum alloy special cutting The pH value of the liquid must be between 8.5-9.5. In addition, the selection of dilution water must be more stringent.

Since many ions in the water have corrosive effects on aluminum, if the water content of these ions is too much, it will reduce the anti-rust properties of the cutting fluid, especially in the anti-rust in the process, such as chloride ion, sulfate ion and its Heavy metal ions, etc.

Try to choose the dilution water with less hardness, or the dilution water softened by ion exchange, to ensure the use and service life of the cutting fluid.
