We use multi‑axis CNC and live tooling to cut setups and lead time:

• CNC mill‑turn aerospace parts with turning, drilling, and milling in one hit
• Fewer operations, faster changeovers, and quicker response on urgent orders
• Strong support for aerospace component prototyping and PPAP / first article builds

Cost‑effective for complex rotational parts

You get both precision and value:

• Efficient cycle times for custom CNC turned aerospace components
• Reduced tooling and handling cost for complex parts with cross‑holes, flats, and slots
• Scalable from prototype to production for engineered aerospace turning solutions

If you need tight tolerance aerospace bushings and fasteners, hydraulic fittings, or turned landing gear parts, we build them to spec and price them to work for real‑world programs.

Materials for aerospace turning parts

Titanium aerospace turning parts (Ti‑6Al‑4V and others)

For critical, high‑load locations, I usually recommend titanium aerospace turning parts, especially Ti‑6Al‑4V and similar grades. They deliver:

• High strength‑to‑weight ratio for shafts, pins, and structural lugs
• Excellent corrosion resistance in harsh flight environments
• Good fatigue performance for long‑life, safety‑critical components

Typical titanium turned parts include landing gear pins, engine mounts, and structural aerospace shafts where every gram matters.

Aluminum alloy turned parts for aircraft structures

For lighter duty or larger structural features, aluminum alloy turned parts are the go‑to choice:

• Very low weight for aircraft structural turned parts and housings
• Good machinability for cost‑effective CNC turning of complex features
• Solid strength and stiffness in common aerospace grades (e.g., 6061, 7075)

We use aluminum turning a lot for aircraft fittings, bushings, spacers, and interior / avionics hardware where high volume and tight tolerance meet cost pressure.

Inconel and superalloy turning for hot‑section parts

When you’re near the engine hot section, you’re in Inconel and nickel superalloy territory. These precision aerospace turning parts are designed for:

• Extreme temperature resistance in turbine and exhaust areas
• High strength under continuous thermal stress
• Resistance to oxidation and creep

Inconel turned aerospace components are ideal for engine shafts, high‑temp fittings, rings, and couplings that run close to the flame.

Stainless steel turned fasteners and high‑stress components

Stainless steel remains a staple for aerospace bushings and fasteners, as well as hydraulic and structural interfaces. It offers:

• High tensile strength and toughness
• Good corrosion resistance for exposed hardware
• Stable, predictable machinability for repeatable high‑precision turning

For more detail on stainless grades we use, you can check our stainless steel machining materials overview.

Material traceability, test reports, and certifications

For aerospace rotational parts machining, material paperwork matters as much as the metal itself. We provide:

• Full heat and lot traceability for every bar and forging
• Mill certs and test reports (chemical and mechanical)
• Compliance with aerospace specs (AMS, ASTM, EN, GB, etc.)
• Support for FAIRs and customer‑specific documentation

Every custom CNC turned aerospace component can be traced back to the original material source, which is key for global OEMs and Tier 1s.

How to choose the right material for your aerospace turning parts

When I help customers pick materials for precision aerospace turning parts, we usually balance:

• Environment: temperature, fluids, corrosion, vibration
• Load case: static vs. fatigue, peak loads, safety factors
• Weight targets: titanium or aluminum vs. steel and superalloys
• Cost and manufacturability: cycle time, tool wear, material price
• Certification needs: existing approvals, fleet commonality, qualification effort

If you’re unsure, send us your 3D model, 2D drawing, and operating conditions and we’ll recommend a material and machining route that hits your performance targets without blowing up cost.

CNC turning capabilities and specifications

When it comes to aerospace turning parts, capability and consistency matter more than anything. We’ve built our setup around high‑precision, production‑ready turning for global aerospace programs.

Max turning diameter and length for aerospace parts

We size our machines to handle most common aerospace rotational parts:

• Max turning diameter: typically up to 300–400 mm depending on the machine and feature set
• Max turning length: up to 500–800 mm for shafts, pins, and axles
• Ideal for aerospace shafts and pins, bushings, landing gear hardware, and engine collars

If you’re not sure your part will fit, send the model and we’ll confirm feasibility based on our CNC machining services.

Achievable tolerances for critical turned features

For tight‑tolerance aerospace turning parts, we design the process to hold:

• Typical turned features: ±0.01 mm (±0.0004 in)
• Critical diameters / fits: down to ±0.005 mm or better with process control
• Runout / concentricity: tightly controlled on bearing seats, sealing diameters, and spline locations

We match tolerance strategy to function: press fits, bearing fits, hydraulic sealing, and flight‑critical locations.

CNC turning, Swiss turning, and mill‑turn options

We combine different technologies to cover the full range of custom CNC turned aerospace components:

• CNC turning centers: ideal for medium–large aerospace rotational parts
• Swiss turning aerospace components: perfect for small diameters, long slender parts, and precision pins
• CNC mill‑turn aerospace parts: for parts that blend turned features with milled flats, ports, and complex forms in one setup

This mix keeps your parts accurate, stable, and cost‑effective.

Live tooling and complex feature machining

With live tooling and multi‑axis turning, we can machine more in a single clamp:

• Cross‑holes, radial ports, keyways, and slots
• Milled pads, mounting features, and complex faces
• Integrated hex, wrench flats, and custom drive features

This is a big win for precision turned aerospace fittings, hydraulic connectors, and compact engine components.

Secondary operations and finishing

We don’t stop at the lathe. For aerospace rotational parts machining, we support complete processing:

• Threading: metric, UN, UNJ, NPT, custom threads
• Grinding: OD/ID grinding for ultra‑tight fits and surface quality
• Coatings and treatments: anodizing, passivation, nitriding, plating, dry film lube, and more
