Custom parts cnc machine component for aerospace

This component features an overall multi-step, hollow structure design, integrating an external threaded interface, an annular flange, a column-supported cavity, and a bottom mounting window, with high requirements for coaxiality, perpendicularity, and overall rigidity. Machining is typically accomplished using CNC turning-milling compound or 5-axis linkage machining processes. First, CNC turning is used to form the outer circle, inner hole, steps, and precision threads. Then, multi-axis milling is combined to complete the flange tooth profile, lateral slotting, mounting holes, and weight-reducing structures. Key positioning surfaces and mating surfaces need to be finished in one or a few clamping operations to ensure axis consistency and assembly accuracy. During the machining process, emphasis is placed on controlling the inner cavity dimensions, flange flatness, and thread precision. The surface of the finished product is usually subjected to precision polishing or passivation treat…
