CNC Machined Anodized Aluminum Parts

What’s CNC

CNC (Computer Numerical Control) machine runs on a computer program; it can either be for prototyping or in full item production. Aluminum is the commonly machined material, as it exhibits excellent machinability, and is thus the preferred material in the most manufacturing sector.

Aluminum as a material offers some interesting thermal and mechanical properties. Besides, the aluminum metal is relatively easy to shape, especially in drilling processes, like in CNC aluminum machining. In fact, we highly regard an aluminum alloy compared to other lightweight metals such as magnesium and titanium alloys.

The use of CNC aluminum has grown immensely, the production of CNC automotive parts and other CNC parts that are lightweight has been intense.

Aluminum is a lightweight, non-magnetic, silver-colored metal that can be formed into almost any shape, it is a metal which is composed of multi alloy element base on aluminum as matrix element, there are various types of aluminum alloys, every alloy has the different characteristics. The most popular material for prototype is 6061 aluminum. It has excellent strength and processing properties, easy to anodizing, and it has various colors can be obtained by anodizing. And the surface texture of machined parts has good look, can be used to make appearance and structural parts.

What's CNC Machining

CNC machining is a common subtractive manufacturing technology, different from additive manufacturing, CNC machining usually starts with a solid workpiece and employs computerized controls and machine tools to remove the material into a required shape.

Why CNC Machining

● CNC machining is the first step to test the product feasibility

● CNC machining is perfect for bridging everything from prototypes to low-volume production and mass production.

● Ability to work with metal and plastic materials.

● It can be processing almost any shape of complex surfaces, And can even process some of the unobservable processing parts.

● CNC machining provides quick lead time.

What’s the difference between the anodize and electrophoresis—Aluminum Extrusion Profile

Electrophoresis is also an electrophoretic paint. It is electroplated onto a material that is not the same as ordinary paint and electrostatic spray. Electrophoresis is the application of lacquer to the surface of a workpiece in the form of ions. The density is quite high, wear-resistant and the surface is smooth and bright.

Anodizing/ Anodized Oxidation is to place the workpiece in a conductive liquid, hang the workpiece on the positive electrode (anode) of the power supply, and electrify to form an oxide film on the surface, called anodization. After the metal is oxidized, it has a protective effect on the surface to protect it from corrosion, high temperature and friction.

How to distinguish anodize and electrophoresis

Scrape electrophoretic material with a blade, See if there is any powder, if have powder, it is electrophoresis surface, if not, it is anodized surface treatment.
