Aluminum CNC Machining Parts:What Cutting Fluid Can Be Used For Anodized Aluminum CNC Machining Parts?

76 | Published by VMT at Dec 18 2021

Aluminum alloy has the characteristics of low physical density, good flexibility, and high plasticity, but its strength is higher, which is close to or exceeds that of high-quality steel. In the CNC cutting process, adhesion will occur, and chips will be formed on the tool. Welding occurs on the cutting edge, so that the tool loses its cutting ability and affects the cutting performance of the tool. Precision and surface roughness of aluminum CNC machining parts . The chemical properties of aluminum alloys are prone to oxidation reactions in the air, resulting in oxidation and blackening of the surface of aluminum CNC machined parts, and even pitting corrosion.

What is cutting fluid? Type of cutting fluid

How to choose the cutting fluid for oxidizing aluminum CNC machining parts?

1. The pH value of aluminum alloy cutting fluid should not be too high, and should be between 8.0 and 8.5.

2. Has good cleaning ability.

3. The formed chips can be taken out from the cutting area.

4. Excellent cooling performance ensures the shape, size and precision of CNC machining of aluminum parts.

5. Aluminum alloy cutting fluid should have good lubrication and anti-friction performance, improve the smoothness and precision of the tool, and extend the service life of the tool.

6. The added rust inhibitor needs to have the ability to inhibit corrosion and maintain a stable pH value. Choose rust inhibitors that can form a protective film on the surface of aluminum CNC machined parts , such as phosphate, sodium silicate, etc., for better results.

7. Excellent corrosion resistance, extremely sensitive aluminum will not produce corrosion spots.

8. Suitable for water treatment of various hardness and aluminum alloy.

9. Good biological stability, long service life, and not easy to produce peculiar smell.

10. Environmental protection. Aluminum cutting fluid does not contain sulfur, chlorine and nitrite and is harmless to the human body.
