Magnesium CNC Machining

Magnesium, a usual material for die casting, is increasingly popular for CNC machining because it is lightweight and highly machinable regarding feed prices. Machined magnesium also generates exceptional surface area finishes due to shorter chips produced throughout the machining process.

Magnesium CNC Machining is challenging because of its high flammability, mainly when processed into chips or powder.

Therefore, fire prevention measures must be taken during machining, including using the right cutting fluids, keeping the work area clean, and preventing chip accumulation. Selecting the right cutting fluid is crucial.

Generally, water-soluble cutting fluids are recommended to help with cooling and fire prevention. Additionally, good ventilation is helpful to prevent magnesium dust from accumulating in the air.

Chips produced during magnesium machining should be cleaned promptly, stored in fire-resistant containers, and properly disposed of to prevent spontaneous combustion.

China CNC machining magnesium parts suppliers know how to follow the tips mentioned above to produce magnesium CNC machined parts.
There are lots of surface finish treatments for magnesium CNC machined parts, like anodizing, powder coating, electroplating, and spray painting.
