Aerospace CNC Machining
Structural brackets, fittings, and housings in aluminum, titanium, and Inconel — with material certs, FAI, and CMM reports tied to your drawing.
Machined Aerospace Parts, Documented End to End
Aerospace CNC machining is unforgiving: thin walls that deflect under clamping, hard alloys that punish the wrong toolpath, and drawings where every dimension traces back to a datum scheme that has to be respected, not approximated. IsoCNC machines structural brackets, fittings, and housings for aerospace and UAV programs — and we document every lot the way your quality team expects: material certificates, first article inspection, and CMM reports tied to your drawing.
Thin-wall aerospace parts are a process problem before they are a machining problem. Our default approach on ribbed and pocketed structure is rough to near-net, relieve stress, then finish in as few setups as the geometry allows — because every re-clamp is a chance to lose the datum. Where the drawing calls out profile and true position across compound angles, the part routes to 5-axis so the critical features finish in one setup, one coordinate system.
Typical Aerospace Parts We Machine
- Structural brackets and fittings — ribbed, pocketed parts roughed from plate or billet, often with weight-reduction geometry that requires 5-axis access
- Housings and enclosures — avionics and actuator housings with tight bore-to-bore position and sealed mating surfaces
- Wing, seat track, and interior components — long, thin parts where fixturing and stress relief matter as much as the cutting
- UAV and drone structures — lightweight frames, motor mounts, and gimbal components in aluminum and titanium
- Turned fittings and bushings — hydraulic and pneumatic connectors, often in 15-5PH, 304, or 7075
Compound-angle and thin-wall work routes to our 5-axis machining centers, where parts finish in fewer setups and hold datums more reliably. For UAV and drone programs especially, where envelopes are tight and revisions come fast, fewer setups also means faster turn on design iterations.
Aerospace Materials
- 7075-T6 / 7050 aluminum — the default structural alloy; strength approaching mild steel at a third of the weight
- Ti-6Al-4V (Grade 5) — fittings, brackets, and fasteners where strength-to-weight and temperature resistance justify the cost; see our titanium machining page
- Inconel 718 — high-temperature engine-adjacent and exhaust components; slow to machine, quoted honestly
- 17-4PH / 15-5PH stainless — corrosion-resistant fittings and hardware
- 6061-T6 — non-critical structure, test fixtures, and ground-support equipment
Every lot ships with a material certificate showing full chemistry, and heat/lot numbers stay tied to the parts through production and packing. That is standard here, not an upcharge. If your drawing requires a specific material standard — AMS, ASTM, or an OEM spec — put it on the RFQ and we source to it, with the cert chain to match.
What Aerospace Buyers Actually Require
Traceability. From mill cert to shipped part, one lot chain, documented. If your PO requires certificate copies with each shipment, that is how we pack.
First article inspection. New part numbers get a full FAI — every dimension, note, and callout measured and reported before production runs the balance. We work to your format: AS9102-style forms or your own template.
GD&T, done properly. True position, profile, and flatness callouts are programmed and measured on CMM against your datum structure — not eyeballed with hand tools. Critical features hold ±0.001 in (±0.025 mm); general features ±0.005 in (±0.13 mm).
Surface integrity. Aerospace drawings care about what machining does to the surface, not just the dimension. We control tool condition and coolant delivery to avoid smeared, torn, or overheated surfaces, and finish to your spec — chem film, anodize Type II/III, passivation, or as-machined per drawing.
One thing we will not do is claim certifications we do not hold. IsoCNC is not AS9100 registered; if your program mandates a registered supplier, we will tell you at RFQ instead of wasting your time. What we do is work to your specification and inspection requirements, and put the documentation in the box to prove it. Details on our inspection capability are on the quality inspection page.

Quote Your Aerospace Parts
Upload STEP files and drawings. Tell us your documentation requirements up front — FAI format, cert copies, inspection level — and we quote them into the job instead of adding them later. If a feature looks risky as drawn, you get DFM feedback with the quote, not a surprise after the first article. Response within 1–2 business days.
