Explore typical aerospace machining applications, including landing gear components, engine shafts, structural components, and hydraulic components. Select a machining case to view workpiece information, machining challenges, and the recommended machining solution.
Aircraft landing gear axles, support shafts, wheel axles, and related components are critical load-bearing parts used during aircraft takeoff and landing. Commonly manufactured from high-strength alloy steel, stainless steel, and other aerospace-grade materials, they feature external diameters, shoulders, grooves, threads, and mounting features requiring high dimensional accuracy, concentricity, and surface quality.
High-strength materials and long, heavy workpieces can generate significant cutting forces, vibration, and deflection during machining. Different shaft diameters and shoulders require accurate concentricity, while critical mounting areas demand consistent dimensions and surface quality for reliable assembly and long-term operation.
Appropriate workholding and auxiliary support should be selected according to the shaft length, diameter and material characteristics. Rough, semi-finish and finish turning can be performed in stages to control machining allowance and deformation. Long bar stock can first be cut to length using a GOLDCNC GZ4250 Metal Band Saw Machine, followed by a GOLDCNC CAK6166 CNC Lathe Machine for external diameters, end faces, shoulders, grooves and threads. CNC machining centers can be added for components with complex mounting holes or milling features.

Aircraft engine shafts, turbine shafts, and compressor shafts are critical rotating components in aircraft engine power transmission systems. Commonly manufactured from high-strength alloy steel, heat-resistant alloys, and other high-performance materials, they feature multiple diameters, shoulders, grooves, end faces, and threads requiring precise CNC machining.
Multiple shaft diameters and stepped sections require high concentricity and dimensional consistency across different machining areas. High-strength and heat-resistant materials can generate significant cutting forces, while long shafts may be prone to vibration and deflection, making machine rigidity, workholding, and stable cutting conditions essential.
High-rigidity workholding should be selected according to the shaft dimensions and material, with roughing, semi-finishing and finishing operations performed in controlled stages to gradually reduce machining allowance. Multiple external diameters, end faces and shoulders can be machined on a CNC lathe, while grooves and threads can be completed using appropriate turning processes according to the component design. The GOLDCNC CAK6150 CNC Lathe Machine is recommended for different aerospace shaft sizes, while a CNC machining center can be added for components requiring complex milling features.

Aircraft structural components, wing fittings, support brackets, and mounting bases are widely used in fuselage, wing, and internal structural systems. Commonly manufactured from aluminum alloys and other lightweight high-strength materials, they feature complex profiles, thin walls, pockets, mounting surfaces, holes, and slots, making them typical applications for CNC milling of aerospace components.
Lightweight aerospace structures often combine thin walls, deep pockets, and complex profiles, making them susceptible to deformation and vibration during material removal. Multiple mounting surfaces and hole patterns also require accurate positional relationships, while repeated setups can introduce datum changes and affect overall machining consistency.
Stable positioning and workholding should be selected according to the component structure, while appropriate tool paths and cutting parameters help control cutting forces in thin-wall areas. For complex structural components, datum surfaces, mounting surfaces, hole patterns and slots can be machined as much as possible on a CNC machining center to reduce repeated setups. The GOLDCNC VMC850 / VMC1160 / VMC1270 Vertical Machining Center is recommended for different aerospace component sizes, supporting milling, drilling, tapping and precision machining operations.

Aerospace hydraulic valve bodies, cylinder housings, and pump bodies are used in aircraft landing gear, flight control, and actuation systems. Commonly manufactured from aluminum alloys, stainless steel, or high-strength steel, they feature precision bores, intersecting hydraulic passages, mounting holes, threaded holes, and sealing surfaces, making them typical applications for CNC machining of aerospace hydraulic components.
Compact hydraulic components often contain multiple holes and internal passages in different directions, requiring accurate control of bore dimensions, depths, and positional relationships. Intersecting passages also require stable tooling and effective chip evacuation, while sealing surfaces demand precise dimensions and good surface finish for reliable hydraulic performance.
A consistent machining datum should be established according to the geometry of the hydraulic valve body or cylinder housing, while appropriate fixtures can reduce repeated setups. Drilling, boring, tapping and finishing operations should be arranged according to the hole pattern and component structure. For intersecting hydraulic passages and multi-directional holes, centralized multi-process machining can help improve positional accuracy between critical features.
