While micro milling has been successfully applied in manufacturing bio-medical components, embossing dies and micro encoders, the breakage of the tool bit has been identified by many users as a teething problem.
How To Machine Magnesium?
The main concern in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire may occur when the melting point of the alloy (400-600 degrees Celsius) is exceeded during machining.
How To Make Lighter and Thinner Magnesium Components?
The most common methods to produce magnesium parts are die casting and thixomolding processes. However, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of between 0.7mm to 1.2mm.
