5 Axis CNC Machining for Aerospace

hy Use 5-Axis CNC Machining for Aerospace Parts?

Aerospace components often feature curved surfaces, deep pockets, angled holes, thin walls, and complex three-dimensional geometries that can be difficult to manufacture with conventional 3-axis machining.

5-axis CNC machining provides several advantages:

• Machining of complex geometries in fewer setups
• Improved positional accuracy
• Reduced fixture changes
• Better tool access to multiple surfaces
• Consistent surface finishes
• Reduced risk of cumulative positioning errors
• Efficient production of lightweight aerospace structures

This makes 5-axis machining particularly suitable for high-precision aerospace components with complex designs.

Aerospace Components We Machine

Our 5-axis CNC machining capabilities can be used to manufacture:

• Aircraft structural components
• Aerospace brackets
• Lightweight mounting components
• Avionics housings
• UAV and drone components
• Aircraft fittings
• Sensor mounts
• Complex aerospace connectors
• Engine-related precision components
• Custom aerospace prototypes

Components can be manufactured from customer-supplied 2D drawings, 3D CAD models, or engineering specifications.

Aerospace Materials

We provide 5-axis machining for a variety of aerospace materials, including:

Aluminum Alloys

• 6061-T6
• 7075-T6
• 2024
• 7050

Aluminum is widely selected for lightweight aerospace components because of its excellent strength-to-weight ratio and machinability.

Titanium

Titanium alloys are suitable for components requiring high strength, corrosion resistance, and excellent performance under demanding operating conditions.

Stainless Steel

Stainless steel can be machined for aerospace components requiring higher strength, wear resistance, and corrosion resistance.

5-Axis Aerospace Machining Capabilities

Our machining process can support complex features such as:

• Multi-angle surfaces
• Contoured profiles
• Deep pockets
• Precision holes
• Thin-wall structures
• Complex internal features
• Compound-angle geometries

For suitable components, 5-axis machining reduces the need to reposition the workpiece, helping maintain the relationship between critical features.

Precision and Quality Control

Aerospace components require consistent dimensional control throughout production.

Our inspection process can include:

• CMM dimensional inspection
• In-process inspection
• Final dimensional inspection
• Surface roughness measurement
• Material verification
• Inspection reports
• Production traceability

For critical components, machining tolerances can be controlled according to customer drawings and application requirements, with precision down to ±0.01 mm on selected features when the part geometry and process allow.

Surface Finishing for Aerospace Components

After CNC machining, aerospace parts can receive additional surface treatments according to application requirements.

Available options include:

• Anodizing
• Hard anodizing
• Alodine / chemical conversion coating
• Passivation
• Electroless nickel plating
• Bead blasting
• Precision polishing

These treatments can improve corrosion resistance, wear resistance, surface protection, or functional performance.

5-Axis CNC Machining for Aerospace Prototypes and Production

5-axis CNC machining is suitable for both prototype development and production aerospace components.

For prototypes, it allows engineers to quickly evaluate complex designs without investing in dedicated tooling. For repeat production, optimized CNC programs, fixtures, and inspection procedures help maintain consistent part quality across batches.

We support projects from prototype quantities to repeat production, depending on component requirements and production volume.
