What is Magnesium CNC Machining?

Magnesium CNC machining is a specialized process that involves the use of Computer Numerical Control (CNC) technology to manufacture parts from magnesium alloys. This process is notable for its unique properties and challenges, which I will outline step by step.

Advantages of Magnesium Alloy for Machining Parts

Magnesium alloy is an excellent choice for customized machining parts, offering high rigidity, good heat dissipation, light weight, high strength, and superior impact load capacity compared to aluminum alloys. It also provides strong corrosion resistance to organic substances and alkalis.

Precision and Accuracy: CNC machining ensures high precision and repeatability, essential for manufacturing components with tight tolerances.

Reduced Labor: CNC machines can operate autonomously, allowing machinists to focus on other tasks while the machine runs.

Flexibility: CNC machining easily accommodates design changes, making it suitable for both custom one-off parts and small to medium production runs.

Key Properties of Magnesium Alloys

Magnesium alloys have a density of about 1.8g/cm³, with high strength, a large elastic modulus, and excellent heat dissipation and shock absorption. Their impact load capacity is higher than that of aluminum alloys, and they also have good corrosion resistance to organic substances and alkalis.

The Characteristics of Magnesium Parts Can be Summarized as:

CNC machining magnesium parts have high strength, the ratio of strength to quality of magnesium alloy is high, and it has a certain bearing capacity.
Magnesium parts have small elastic modulus, good rigidity, strong shock resistance, and are not easily deformed after long-term use.
Magnesium machining parts have good resistance to electromagnetic interference and shielding.
Magnesium machining parts do not pollute the environment.

Common surface treatment methods of magnesium machining parts are roughly divided into: Surface coating of oil and wax, chemical treatment, anodizing, spraying, electroplating, chemical nickel, and non-chromium film.

No matter what kind of personalized design you have, Shenzhen YIJIN Hardware will wholeheartedly provide you with custom metal fabrication services.

Magnesium Machining – FAQs

What should I do if the CNC machining parts of magnesium alloys corrode?

There are four main methods for anti-corrosion of magnesium alloy parts: chemical conversion treatment, anodizing, metal coating, and laser treatment.

There are many processing and surface treatment methods for magnesium alloy parts. Shenzhen YIJIN Hardware has more than 20 years of rich experience in the hardware industry and accepts customized processing of various magnesium alloy parts.

We are the source manufacturer of CNC processing, and the price is more advantageous.

What are the challenges in magnesium CNC machining?

Flammability: Magnesium is highly flammable, especially in the form of fine chips or dust. This requires strict safety measures, such as dust collection systems and fire suppression equipment.
Tool Wear: Magnesium’s abrasive nature can cause rapid tool wear. Using appropriate cutting tools, like carbide or specialized coatings, is essential to extend tool life.
Coolant Use: While some operations can be performed dry, using the right coolant is often necessary to reduce heat and improve surface finish. However, care must be taken to choose coolants that do not react with magnesium.

What is the CNC machining process for magnesium?

Material Selection: Choose the right magnesium alloy (e.g., AZ31, AZ61, or ZK60) based on the desired mechanical properties.
CAD Design: The part is designed using CAD software to create an accurate model.
CAM Programming: The CAD model is converted into a CNC program (G-code) using CAM software to define machining operations and tool paths.
Setup: The CNC machine is prepared with the correct tools and fixtures to securely hold the magnesium workpiece.
Machining Operations: The CNC machine carries out operations such as milling, turning, drilling, and tapping.
