Aluminum CNC machining has many characteristics. First of all, the density of aluminum alloy is small, the weight is light, and the load on the equipment is small during the processing, which is conducive to high-speed cutting and improving processing efficiency. Secondly, its cutting performance is good, the cutting force is small, the tool wear is relatively slow, and the processing cost can be reduced. The thermal conductivity of aluminum alloy is good, and the heat generated during processing can be quickly dispersed, reducing the influence of thermal deformation on the processing accuracy. Moreover, its machinability is strong, and it can be easily manufactured by CNC machining to produce a variety of complex shapes, such as thin-wall structures, complex surfaces, etc., Mastersdex processed products are widely used in aerospace, automotive manufacturing and electronic equipment enclosures and other fields.
