1, aluminum alloy hardness is low
Compared with titanium and other hardened steel, aluminum alloy hardness is lower, of course, heat treatment, or die-casting aluminum alloy is also very high hardness. Ordinary aluminum HRC hardness are generally HRC40 degrees below. Therefore, the processing of aluminum alloy, the cutter load is small. Because of the better thermal conductivity of aluminum alloy, milling aluminum alloy cutting temperature is relatively low, can increase its milling speed.
2, low plasticity of aluminum alloy
Aluminum plastic low, low melting point. When processing aluminum alloy sticking knife when the problem is serious, poor chip performance, surface roughness is relatively high. In fact, the main processing aluminum alloy knife and roughness is not good. As long as the solution to the stick knife, the quality of the two surface processing problems, aluminum processing problems to be solved.
3, easy to wear knives
Because it is not suitable for cutting tool materials, aluminum processing, often because of sticky knife, chip removal and other issues lead to accelerated tool wear.
