CNC Turning for Aerospace
CNC turning for aerospace shafts, bushings, hydraulic fittings, and rotational housings — concentricity and repeatability held across long-running system programs.
- Typical Tolerance
- ±0.0005"
- Primary Materials
- Aluminum · Titanium · Stainless
- Production
- Prototype → Production
- Machine Type
- Live-tool CNC lathes with sub-spindle
Why Aerospace Manufacturers Use CNC Turning
- CNC Turning suits rotationally symmetric components — shafts, bushings, fittings, and housings — where concentricity and repeatability matter, which is common across aerospace programs.
- Live tooling produces cross-holes and flats in a single setup.
- Sub-spindle transfer completes both ends without secondary handling.
- Bar feed supports predictable cycle time on production quantities.
- AS9102 First Article Inspection when flowed down on CNC turning programs.

CNC Turning for Aerospace — FAQs
The questions engineering and procurement teams ask most often before a first quote.
What aerospace components are well suited to CNC Turning?
CNC Turning suits rotationally symmetric components — shafts, bushings, fittings, and housings — where concentricity and repeatability matter. Typical aerospace parts include Bushings and precision hardware.
What tolerances are typical for aerospace CNC turning?
Northline holds ±0.0005" as a typical envelope on CNC Turning, with tighter callouts held on qualified features and reviewed against process capability during quoting.
Which aerospace materials can Northline CNC turn?
Common aerospace materials include Aluminum 6061 / 7075 / 2024, Titanium Ti-6Al-4V, Stainless 304 / 316 / 17-4 PH, Inconel 625 / 718. Grade selection and heat/lot traceability are maintained; alternates are reviewed during quoting.
Can Northline provide First Article Inspection documentation?
Yes. AS9102-format First Article Inspection reports are available on request. Northline is ISO 9001:2015, AS9100D, and ITAR registered.
Can you support both prototype and repeat aerospace production?
Yes. The same setups used for prototype and first-article carry into repeat production, so geometry and inspection results carry forward without a process change.
How do you control aerospace-specific engineering considerations on CNC Turning?
Long-length-to-diameter parts supported with steady-rest and tail-stock strategy. Datum strategy, inspection frequency, and fixturing are reviewed during quoting against the specific aerospace drawing requirements.
