How many methods and surface treatments about CNC machining aluminum surface oxidation?

The chemical properties of aluminum itself are very active, but the surface of the aluminum alloy will form a dense CNC Machining Aluminum oxide film to prevent the internal aluminum from continuing to be oxidized by the aluminum alloy for surface oxidation treatment in order to artificially thicken the aluminum oxide film to strengthen the aluminum alloy The corrosion resistance and wear resistance of the product.

Six methods of surface treatment

1. Metal plating method:
It is more common, and there is a process of electroplating after polishing.

2. Oxidation (coloring):
The application of aluminum surface treatment and oxidation is divided into two aspects, enhancing physical properties and achieving the purpose of coloring.

3. Rubbing:
It is called wire drawing, which is similar to the car pattern. They all form a smooth continuous pattern on the surface. The difference is that the car pattern is shown as a circular pattern, and the rubbing pattern is a straight line pattern.

4. Sandblasting:
It is used to overcome and conceal some defects of aluminum alloy in the Machining process, and to meet some special requirements of customers for product appearance. There are glass sand, tungsten sand, etc., which present different feelings, similar to the rough texture of ground glass, and fine sand molds can also show high-end products.

5. Polishing:
Overcome defects, deburr and brighten the surface.

6. Car pattern:
Aluminum surface treatment is a processing method for reprocessing after the mold is formed. The texture is processed by a lathe, and the overall performance is extremely regular texture characteristics.
