Characteristics of CNC aluminum parts processing

  1.  Aluminum alloys have low plasticity

Aluminum alloy has low plasticity and low melting point. When machining aluminum alloys, the sticking problem is serious, the chip removal performance is poor, and the surface roughness is relatively high. In fact, the processing of aluminum alloy is mainly due to the poor effect of sticking and roughness. As long as the two major problems of sticking the knife and machining surface quality are solved, the problem of CNC aluminum parts processing will be solved easily.

  1. Low hardness of aluminum alloy

Compared with titanium alloys and other hardened 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 is generally below HRC 40 degrees. Therefore, when machining aluminum alloys, the load of the tool is small. And because the thermal conductivity of aluminum alloy is better, the cutting temperature of milling aluminum alloy is relatively low, which can improve the milling speed.

  1. The tool is easy to wear

Because of the use of unsuitable tool materials, when cnc aluminum parts are processed, the tool wear is often accelerated due to problems such as sticking and chip removal.
