Magnesium CNC Machining Services

Magnesium, a unique metal material in the CNC machine tool workshop, poses high processing risks due to its flammability. Experience

in magnesium machining is crucial for engineers.

The high thermal conductivity and the mechanical properties of magnesium make it one of the easiest materials for metal CNC machines. It is also a lightweight metal, about 35% lighter than aluminum, making it ideal for use in the automotive and aerospace industries.

However, there are risks to CNC milling magnesium, which include fire hazards as this material can burn underwater, nitrogen, and even CO2.

Pros and Cons of Magnesium CNC Parts

The surface treatment of CNC magnesium alloy parts varies greatly depending on the application and function.

• Anodizing: Enhances corrosion resistance and durability through a protective oxide layer on magnesium parts.
• Chromate Conversion Coating (Alodine): Improves corrosion resistance and surface adhesion, preparing the parts for painting.
• Electroless Nickel Plating: Adds a uniform, wear-resistant layer to magnesium components, increasing their durability.
• Powder Coating: Applies a thick, protective layer that is resistant to chipping and scratching, ideal for parts that face harsh conditions.
• Painting: Provides color customization and additional protection against environmental factors.
• Passivation: Treats the surface to reduce chemical reactivity and prevent corrosion on magnesium parts.

Magnesium Machining Benefits

Application Range:

Car engine accessory bracket, clutch housing, gearbox housing, instrument panel frame, steering wheel frame, seat frame, valve body mobile phone,Drone/camera.Magnesium alloy is very suitable for this kind of product because it is very light.

Why is magnesium hazardous?

While a magnesium workpiece is very difficult to ignite, the material becomes highly flammable when turned into powder or shavings.

This means the chips from machined magnesium can pose a fire safety risk.

That risk to machine shops is heightened because magnesium-induced fires are very difficult to extinguish. The combustion will persevere in nitrogen, carbon dioxide and water. (This is why magnesium powders have historically been used in some explosive devices.)

The Characteristics of Magnesium Parts Can be as follows:

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

How to safely machine magnesium?

Although it might sound daunting, it is perfectly safe to CNC machine magnesium if the right precautions are taken.

Avoid tight clearance angles

Although magnesium can be machined at fast speeds without compromising the quality of the part,

it is best to avoid tight clearance angles, because contact between the tool and workpiece increases friction and cutting temperature.

Maintain proper tool condition

Sharp cutting tools can reduce the fire hazard of machining magnesium.
Dull tools can rub and cause friction, which causes sparks and builds up heat where the sensitive magnesium chips

are being created. Needless to say, sharp tools will also produce better parts.
Most machinists use a carbide cutting tool with a large relief angle for machining magnesium.

Avoid water-based coolant

Although coolants reduce machining temperatures, a water-based coolant can actually increase the risk of a magnesium fire

as it will produce hydrogen gas.Avoid coolant altogether, or use a light mineral oil in place of standard coolant. Compressed air

or argon gas can also be used to reduce temperatures without the risk of exacerbating a potential fire.
