Since people's living standards have improved, the precision of aluminum handicrafts has become more and more stringent, thereby improving the aluminum alloy cnc processing technology. Aluminum alloy CNC machining is the use of CNC machine tools to process parts. Aluminum alloy cnc machining is a machining method that uses digital information to control the displacement of parts and cutters. Below, the editor of Huachenxin Technology will discuss the three characteristics of aluminum alloy cnc processing in detail.
1. Aluminum alloy has low hardness.
Compared with titanium alloys and hardened steels, aluminum alloys have lower hardness. Of course, heat-treated or die-cast aluminum alloys also have higher hardness. Generally, the HRC hardness of aluminum plates is generally below HRC40 degrees. Therefore, in the case of processing aluminum alloy, the load of the tool is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, and the milling speed can be increased.
Second, the plasticity of aluminum alloy is low
Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the joint edge problem is very deep, the chip removal performance is poor, and the surface roughness is also high. In fact, the main reason for processing aluminum alloy is that the effect of knife and roughness is not good. If the two problems of the fixed blade and the quality of the machined surface are solved, the problem of aluminum alloy machining can be solved.
Third, the tool is easy to wear
Due to the use of inappropriate tool materials, in the case of processing aluminum alloys, tool wear is often accelerated due to problems such as bar blades and chip discharge.
