How To Machine Magnesium?

Izvor: KiWi

Magnesium has been utilized in production portable computers structures, video cameras, digital cameras, PDAs and other gadgets products and services due to its high strength to weight ratio. When magnesium is alloyed with aluminum, the resulting material is quite light and powerful, and easily machinable messer cutting and welding .

The main problem in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire may possibly occur when the melting point of the combination (400-600 degrees Celsius) is exceeded all through machining. The little chips and fine dust generated throughout cutting will also be highly flammable and create a critical fire risk or even correctly managed.

There are several things to note when machining magnesium:

Firstly, make use of a lower cutting speed when compared to cutting aluminum. The workpiece temperature goes up having an upsurge in cutting speed and also smaller undeformed chip thickness. In other words, the slower the machining speed and the more expensive the chips, the lower the workpiece temperature is likely to be. As a result of this reason, some organizations have modified woodworking tools for machining magnesium so as to achieve greater chips and lower fire hazard.The cutting tools used should have aid and clearance angles that are sufficiently large to stop unnecessary cutting tool-workpiece friction, thus reducing the heat generated throughout the cutting process messer cs oxyfuel technology catalogue .

Minute, keep the machining center clear. Keeping the magnesium chips correctly and washing the machining centers frequently are very important aspects of machining magnesium. Keep a container of cast iron chips near by when machining magnesium, If fire does occur, smother the fire with the cast iron chips.

Thirdly, if coolants are essential for high speed machining, don't use water-based lubricants. Instead work with a light mineral oil, or even a water-soluble cutting liquid such as Castrol Hysol MG specifically formulated for machining magnesium. Some businesses in Japan use semi-dry machining with a misting system.

The last point is to observe the workpiece temperature during machining. Experiments were carried out using thermocouples fitted to the workpiece to observe the workpiece temperature during equipment. Dry cutting of magnesium metal thin walls was accomplished using cutting velocity of 440m/min for roughing and 628m/min for fine finishing read mg messer .

Inspite of the fire hazards, magnesium becomes increasingly utilized in electronics services and products, and as competition from overseas low-cost production bases intensifies, most machining work retailers could very well find machining of magnesium a niche worth pursuing.
