How To Machine Magnesium?
Magnesium has been utilized in production notebook computer structures, movie cameras, electronic cameras, PDAs and other consumer electronics products due to the high strength to weight ratio. When magnesium is alloyed with aluminum, the resultant material is powerful and very gentle, and easily machinable.
The main issue in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire might occur if the melting point of the alloy (400-600 degrees Celsius) is exceeded throughout machining. The fine dust and small chips produced throughout cutting may also be highly flammable and present a serious fire risk or even correctly managed.
There are several points to notice when machining magnesium:
Firstly, use a lower cutting speed in comparison with cutting metal. The temperature increases with the increase in reducing speed and also smaller undeformed chip thickness. Put simply, the slower the machining speed and the more expensive the chips, the lower the workpiece temperature is going to be. Because of this reason, some organizations have altered woodworking tools for machining magnesium in order to obtain bigger chips and lower fire hazard.The cutting tools used must have comfort and clearance angles which are sufficiently large to prevent un-necessary cutting tool-workpiece friction, ergo lowering the heat developed through the cutting process.
2nd, keep the machining center clean. Cleaning the machining centers frequently and holding the magnesium chips effectively are very important areas of machining magnesium. Keep a pot of cast iron chips not far from when machining magnesium, If fire does occur, smother the fire using the cast iron chips.
