Aluminum alloy CNC processing three major characteristics

First, low hardness of aluminum alloy.

Aluminium alloys have a lower hardness than titanium alloys and hardened steels, and of course, heat treated or die-cast aluminum alloys have a higher hardness. The HRC hardness of general aluminum plate is generally below HRC40 degrees. Therefore, in the case of machining aluminium alloys, the tool load is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed.

Two, the plasticity of aluminum alloy is low

Aluminum alloy has low plasticity and low melting point. When aluminum alloy is processed, the combination edge problem is very deep, the performance of chip removal is poor, and the surface roughness is also high. In fact, the processing of aluminum alloy, mainly knife and roughness effect is not good. If we solve the two problems of fixed blade and processing surface quality, we can solve the problem of aluminum alloy processing.

Three, tool easy to wear

Because of the use of inappropriate tool materials, in the case of aluminum alloy processing, because of the bar edge, chip discharge and other problems, the tool wear is accelerated.
