This component is a high-complexity precision structural shell part, typically used in aerospace and high-end industrial systems, with strict requirements for structural strength, dimensional stability, and assembly accuracy. The part is made of high-performance metal materials and is integrally formed through multi-process CNC precision machining. In the finishing stage, parts are processed using multi-axis machining centers or turn-mill composite equipment to perform high-precision cutting on multi-stage inner holes, complex cavities, mounting planes, and functional interfaces. During the processing, through reasonable clamping schemes and process planning, emphasis is placed on ensuring the positional accuracy, coaxiality, and perpendicularity between various functional cavities to meet the requirements of assembly and system operation.
The internal threads and interface parts are processed using precision cutting or forming techniques to ensure thread accuracy, smooth assembly, and reliable sealing. Key hole positions are subjected to precision boring or reaming according to usage requirements to achieve stable dimensional accuracy and good surface quality. All sharp edges undergo uniform chamfering and deburring to reduce the risk of stress concentration and improve part reliability.
The processing flow starts with raw material inspection and preprocessing to ensure that the material composition, internal structure, and mechanical properties meet the design requirements. This is followed by CNC rough machining, where the preliminary shaping of the main body (contour), key cavities, and datum planes is completed through CNC turning and milling processes, establishing a stable machining datum for subsequent finishing operations.
After processing, the parts undergo a rigorous quality inspection process, which conducts a comprehensive inspection of key dimensions, geometric tolerances, and thread quality. According to project requirements, supporting surface treatment and cleaning processes can be provided to meet the requirements of corrosion resistance, wear resistance, or special service environments. Such components are suitable for aerospace and high-end industrial application scenarios that have extremely high requirements for reliability, stability, and long-term performance.
