1. Characteristics of CNC machining aluminum alloy
1. Low hardness of aluminum alloy
Compared with other metal materials, aluminum alloy has lower hardness, so it has good cutting performance, but at the same time, due to its low melting point and high ductility, it is very easy to melt on the finished surface or tool, and it is also easy to produce burrs and other deficiencies. Heat-treated or die-cast aluminum alloys also have higher hardness. The HRC hardness of general aluminum plates is below 40 degrees, which is not a high-hardness material. Therefore, during the
2. Low plasticity of aluminum alloy
3. During the processing of aluminum parts, the tool is very easy to wear
2. There are several ways to process aluminum parts:
1-Hot working
2. Cold working
3-Warm working
3. The following matters should be noted when processing aluminum alloys:
1- Setting and controlling the temperature of aluminum profiles. Generally speaking, there is a certain error between the temperature and the displayed temperature. When setting the surface temperature, it should be set according to the actual temperature of the equipment, and pay close attention to the temperature fluctuation
2- Aluminum profile aging and insulation. The aging should be set strictly in accordance with the processing technology requirements, and the insulation time should also be appropriate to prevent insufficient hardness due to insufficient aging or too long aging.
3- The extrusion frame of aluminum profiles should not be too dense, and there should be gaps between materials. The gaps between aluminum profiles, especially small and thick materials without ventilation, need to be larger. When pipes, small materials and sheets are combined in one frame, the pipes are placed below to facilitate aging circulation and air supply.
provide excellent performance and sustainability with their core advantages and environmentally friendly production concepts. The products are made of high-strength aluminum alloy materials, and through precision CNC machining, they achieve the perfect combination of lightweight design and high-strength support. This not only ensures the reliability and durability of aluminum alloy parts under extreme conditions, but also effectively reduces the overall weight of the product, improves operational flexibility and energy efficiency. At the same time, we are committed to environmentally friendly production, optimize energy-saving technologies, implement resource recycling, and strictly control pollution emissions to achieve green production.
