Many people will ask what CNC tools are used for machining and milling aluminum alloys? Currently used machining aluminum parts are mainly divided into two categories: wrought aluminum alloy and cast aluminum alloy. So, for End mills for aluminum, is it better to use End mills for aluminum or aluminum alloy special tools?

Processing characteristics of End mills for aluminum:
1. Aluminum alloy has low hardness
Compared with titanium alloys and other quenched steels, the hardness of aluminum alloys is lower. Of course, the hardness of heat-treated or die-cast aluminum alloys is also very high. The HRC hardness of ordinary aluminum plates are generally below HRC40 degrees. Therefore, when processing aluminum alloy, the load of End mills for aluminum is small. And because the thermal conductivity of End mills for aluminum is better, the cutting temperature of milling aluminum alloy is relatively low, which can increase its milling speed.
2. Low plasticity of aluminum alloy
End mills for aluminum have low plasticity and low melting point. When processing aluminum alloy, the sticking problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the main reason for processing aluminum alloy is that the effect of sticking knife and roughness is not good. As long as the two major problems of sticking knife and processing surface quality are solved, the problem of End mills for aluminum processing will be solved.
3. End mills for aluminum are easy to wear
Due to the use of unsuitable tool materials, when machining aluminum alloys, the wear of End mills for aluminum is often accelerated due to problems such as tool sticking and chip removal.
