CNC routers have a broad range of applications regardless of what sort of material you're working with. Whichever material you select a CNC will have an equivalent benefits; the most ones being superior automation and efficiency. Many CNC machines are often run throughout their whole cycle without the presence of an operator. Another major advantage of this technology is that the high level of accuracy and skill to repeat specifications. meaning that when your program is verified, whether you produce two, 2 hundred or two thousand work pieces, they're going to all be identical.
Though a CNC machine is more often used for cutting wood, it are often used for cutting aluminum (or other non–ferrous metals). For cutting non-ferrous metal it's not such a lot that you simply need a special router but that you simply will got to use it differently.
Here are variety of differences to stay in mind:
The “sweet spot” for metals’ optimum speeds and feeds is far smaller than that of wood. If you don’t stay within this optimum bracket, your cutters are going to begin to wear out much quicker or break frequently and your surface finish will be inferiority.
Some metals, like aluminum have a bent to stay to the cutting tools. Build-up of aluminum deposits on the sides of cutting tools and end in the bit welding itself to the metal. It order to chop successfully with aluminum you should:
use a feeds and speed calculator
use carbide coated bits
clean chips and deposits regularly and thoroughly
make more passes at shallower depths to form cleaning easier
use fewer flutes and increase cut width
don’t reduce the speed rate an excessive amount of
use a mist to lubricate to assist prevent chips from sticking to the cutting edges
