Machining Magnesium

Magnesium is the lightest structural metal and exhibits excellent machinability. Some of the advantages of machining magnesium compared to other commonly used metals include:

• Low power required – approximately 55% of that required for Al.

• Fast machining – employing the use of high cutting speeds, large feed rates and greater depths of cut. •

Excellent surface finish – extremely fine & smooth surface achieved. • Well broken chips – due to the free-cutting qualities of magnesium.

• Reduced tool wear – leading to increased tool life. To fully exploit and enjoy the advantages of machining magnesium, it is important that the unique characteristics of the metal are understood.
