CNC aluminum alloy parts have high precision, high efficiency, the ability to machine complex parts, lightweight design, good corrosion resistance, good thermal conductivity and easy machining and other technical properties. Mainly reflected in the following aspects: (1) High precision: CNC Machining technology can achieve high precision machining, usually sub-millimeter machining accuracy, or even more accurate. This is due to the digitalization and computer control of CNC technology to ensure that the machining of each part is carried out according to the predetermined precise path and size. (2) High efficiency: CNC machining technology controls the movement of machine tools through computer programs, realizing automated production and greatly improving production efficiency. Compared with traditional manual machining methods, CNC machining can complete a large number of machining tasks in a short time. (3) Ability to machine complex parts: CNC aluminum alloy machining can handle parts of various complex shapes, including curved surfaces, hollows, special shapes, etc. This machining method can quickly and accurately complete complex machining tasks, avoiding the problems that require a lot of time and manpower in traditional machining methods. (4) Lightweight design: Aluminum alloy has low density and good strength, which is suitable for lightweight design. CNC machining can realize the processing of aluminum alloy parts according to the design requirements, so that it can reduce weight while maintaining strength. (5) Good corrosion resistance: Aluminum alloy itself has good corrosion resistance, while CNC machining can realize the surface treatment of aluminum alloy parts, such as oxidation, coating, etc., to further improve its corrosion resistance and prolong service life. (6) Good thermal conductivity: Aluminum alloy has excellent thermal conductivity, which can effectively disperse heat and avoid problems caused by overheating. CNC machining can realize the heat dissipation design of aluminum alloy parts according to processing requirements, improve its thermal conduction efficiency, and ensure the normal operation of equipment. (7) Easy machining: Aluminum alloy has good cutting performance and machinability, and is easy to carry out CNC machining, cutting, milling, drilling and other process operations. This makes aluminum alloy an ideal material for manufacturing complex parts.
