Frequently asked questions

Don’t see your question? Request a quote and our engineering team will answer it.

What materials do you machine for aerospace parts?

We machine aerospace aluminum grades 6061, 7075, and 2024, Ti-6Al-4V titanium, 15-5PH and 17-4PH precipitation-hardening stainless steels, 303, 304, and 316 stainless, and Inconel 718 nickel alloy. Material choice drives strength, corrosion resistance, and temperature capability, so our engineering team confirms the best fit against your drawing at the feasibility review.

What tolerances can you hold?

Standard machined tolerance is ±0.005 inch, and we hold down to ±0.0005 inch on critical features verified by CMM. Our engineering team confirms achievable tolerances against your drawing and GD and T callouts at the feasibility review.

Can you machine complex 5-axis geometry and thin walls?

Yes. We run 3, 4, and 5-axis machining, which lets us cut complex contoured geometry and thin-wall features in fewer setups. Fewer setups reduce handling and help hold tight tolerances across the part, which matters on airframe structure and engine hardware.

How do you ensure quality on aerospace parts?

Every aerospace program runs on an ISO 9001 quality-management basis with first article inspection and CMM verification on critical features. Each shipment includes a first article inspection report, a full CMM dimensional report, material traceability with mill certifications, and a Certificate of Conformance. Source inspection is supported on request.

Do you provide material traceability and certifications of conformance?

Yes. Every lot ships with material traceability back to mill certifications and a Certificate of Conformance. Full CMM dimensional reports and first article inspection reports accompany the parts so your incoming inspection has the documentation it needs.

What are your standard lead times?

Standard production lead time is 4 to 8 weeks, with first article timing confirmed at the quote stage. Qualification and low-volume runs can be reviewed case by case.

What surface finishes and secondary operations are available?

Parts ship as-machined or with secondary finishing including anodizing, chromate conversion coating, passivation, plating, heat treatment, and bead blasting. As-machined surfaces reach down to Ra 0.4 micrometres on critical features, and the right finish depends on your corrosion resistance and appearance requirements.

How can I reduce the cost of aerospace CNC machining?

The biggest cost levers are part geometry, material selection, tolerances, and volume. Relaxing tolerances where the design allows, simplifying internal corners, and committing to recurring volume all bring the per-part price down without compromising the features that matter. Our engineering team flags these opportunities during the manufacturability review so the quote reflects the most efficient approach.
