Advantages of Aluminum Alloy in CNC Machining

In the field of CNC precision parts processing, because of the material characteristics of aluminum, aluminum parts are widely used in many fields, so aluminum parts are very common parts.

CNC machining Aluminum Characteristics and Advantages:

1. The hardness of the material is moderate, and the tool wear of the processing equipment and CNC machining center is small.

2. It can be precisely processed into various geometric shapes such as planes, cavities, shells, spheres, arcs, and heterouality.

3. Not easy to get dirty, easy to maintain and clean.

4. It has good durability and is not easy to corrode, and the special surface treatment process makes the service life of the parts longer.

5. Aluminum material is environmentally friendly, can be recycled, and has a high recycling value.

The above five points are the material advantages of aluminum machined parts. Aluminum is a common material in CNC precision parts machining. Its material has moderate hardness, durability and is not easy to corrode. In addition, the cost of the material itself is not high. It is the preferred material for most machined parts manufacturers.

What are the Common Surface Treatment processes for Aluminum CNC Machining Parts?

Before the surface treatment of aluminum products, aluminum materials generally need to be pre-treated: degreasing→rust removal→cleaning→phosphating or purification, etc. Most of the workpieces with rust or thick surface are derusted by mechanical methods such as sandblasting and shot blasting, but the surface of the workpiece should be clean and free of dirt after mechanical derusting.

1. Polishing. Polishing removes surface defects and burrs, etc., making the surface bright and smooth. Polishing can be divided into chemical polishing and mechanical polishing

2. Sandblasting: The purpose of sandblasting is to solve and cover up some defects of aluminum alloy during machining and to meet some special requirements of customers for product appearance. There are glass sand, tungsten sand, etc., showing different feelings, similar to the rough texture of frosted glass, and fine sand molds can also show high-end products.

3. Metal plating. It is more common, and there is a treatment process of electroplating after polishing.

4. Lathe pattern: aluminum surface treatment is the treatment method of reprocessing after the mold is formed. Using a lathe to process the pattern, the finished product shows a very regular texture feature.

5. Brushed Finishes: The performance is similar to that of the car pattern, which forms smooth continuous lines on the surface. The difference is that the car pattern appears as a ring pattern, and the brush finishes appear as a straight line.

6. Oxidation and Anodizing (coloring): The use of aluminum surface treatment oxidation is divided into two aspects, enhancing the physical properties and achieving the purpose of coloring. Generally, it is anodized. The purpose is to color, and the second is to increase the surface hardness and improve wear resistance, such as micro-arc oxidation.

7. Passivation: A method of turning the metal surface into a state that is not easily oxidized, thereby delaying the corrosion rate of the metal.
