Why Choose Aluminum for CNC Machining?

Aluminum is one of the most popular materials for CNC machining due to its unique combination of properties, which makes it ideal for precision manufacturing.

Here are the key advantages of using aluminum in CNC machining:

Lightweight

Aluminum is approximately one-third the weight of steel, making it an ideal material for applications where weight reduction is critical, such as in aerospace and automotive parts.

High Strength-to-Weight Ratio

Despite its lightweight nature, aluminum offers impressive strength and durability, ensuring that it can withstand high-stress environments.

Corrosion Resistance

When exposed to air, aluminum naturally forms an oxide layer that protects it from corrosion, even in harsh environmental conditions.

Excellent Machinability

Aluminum is easier to machine than most other metals, resulting in faster turnaround times, lower costs, and less wear on tools.

Precision and Tight Tolerances

Our CNC machining processes can achieve incredibly tight tolerances when working with aluminum, making it ideal for complex, high-precision components.

Cost-Effective

Aluminum’s machinability and recyclability make it an economical choice for CNC machining, offering both material and production savings.

FAQs

1. Why Do Some Customized Aluminum Alloy Products Turn Black After Anodizing?

YIJIN Hardware reminds you that it may be that your aluminum machining material is not selected correctly, such as using aluminum alloy 7075.

As we all know, the oxidation effect of AL6061 is excellent, while the appearance of 6061 and 7075 materials is similar, and it is difficult to distinguish with the naked eye.

If there is no inspection before processing, and AL7075 is mistakenly processed as AL6061, the above problems will occur.

7075 aluminum is a forged alloy, which is synthesized from a variety of materials. During oxidation, due to the different chemical reactions of each material, the oxidation effect is uneven, and there are even some black spots. If the product is an appearance part, the effect will be greatly discounted.

Therefore, YIJIN Hardware reminds you again that aluminum machining materials, especially those with post-processing requirements, must ensure the authenticity of the raw materials.

As a CNC machining supplier, YIJIN Hardware is specially equipped with a spectrometer that can detect raw materials, so as to ensure the authenticity of the materials.

2. Overview of CNC Machining and Its Relevance in Modern Manufacturing

CNC machine uses computer programs to instruct different tools around various axes.

Computerized Numerical Control abbreviated as CNC describes a system that controls devices precisely through a computer program.

Computer numerically controlled machines can be a router, grinders, laser cutters, welders, milling machines, and so on.

Types of CNC Machining

CNC Milling Machine

This type of CNC machining is used for tapping, drilling, face and shoulder milling, etc.

These mills follow an X, Y, and Z system. A CNC milling machine is controlled by computer programs using letters and numbers.

Plasma Cutting Machine

Plasma cutting machines or plasma torches cut metal materials precisely.

This machine produces heat and speed by using compressed air gas and an electrical arc.

CNC Turning Machine

This type of programmed machine is used to execute complex designs.

When a manual machine can not cut the material meticulously, lathes or CNC turning machines become useful.

This machine has two axes called X and Z and the material is held on the rotating spindle of this machine to perform the function.

Electric Discharge Machine or EDM

EDM has two different models such as wire EDM and sinker EDM.

EDM uses electrodes to create electrical sparks for cutting and shaping materials.

When the gap between the two electrodes reduces, a current flows and removes specific parts of the workpiece.

In this way, EDM works using the spark machining or die sinking technique.

Water Jet Cutting Machines

The high-pressure water jets are used to cut hard materials like metal and stone.

Also, it is used on materials that can not tolerate high temperatures.

3. Relevance of CNC Machining in Modern Manufacturing

CNC machining contributes to the evolving mechanism of the manufacturing Industry. It helps in ensuring rapid prototyping of precise parts with detailed surface finishing.
CNC machining is used to make high-precision parts on large volumes.
As a result, modern manufacturing relies heavily on CNC machining.
