❓ Frequently Asked Questions – Aerospace CNC Turning

🔹 What is the difference between AS9100 and ISO 9001 for machining?
AS9100 includes all ISO 9001 requirements plus additional aerospace‑specific standards for safety, traceability, and risk management. It is mandatory for most aerospace supply chains.
🔹 Can you machine parts longer than 600mm?
Yes, with specialized steady rests. Please contact us with your length requirements for a feasibility review.
🔹 Do you provide full documentation for aerospace projects?
Absolutely – material certificates, in‑process inspection logs, CMM reports, surface finish data, and FAIR (First Article Inspection) are standard.
🔹 What is the typical cost premium for aerospace‑grade turning vs. standard?
Aerospace parts typically cost 30–60% more due to stricter tolerances, certification, traceability, and specialized tooling. We provide transparent quotes with no hidden fees.
