The cutting of aluminum and aluminum in industrial production is very important, so it is very important to introduce the cutting tool and method of aluminum roll. The first kind is not the coating of ultrafine particles carbide tool. The second is hard alloy cutter with aluminized coating method is not common, for example, TiC TiN plating. The third is a very high hardness of diamond tools. Use of the above material cutting tools for cutting aluminum or aluminum, remember that the chip space to the tool is large, usually recommended to use 2 teeth, and to ensure that the front corner, the angle to the big 12 degrees around. If only the general milling surface, then you can with 45 degree angle can be indexable face milling cutter, and equipped with specialized processing aluminum alloy blade, the final presentation effect will be very good.
