Frequently Asked Questions

What tolerance is required for aerospace CNC machining?

Standard aerospace tolerances: ±0.005mm (0.0002") for critical dimensions, ±0.01mm for general features, ±0.025mm for non-critical. Surface finish: Ra 0.8 μm (32 μinch) typical, Ra 0.4 μm (16 μinch) for sealing surfaces.

How long does NADCAP certification take?

Initial NADCAP audit: 3-5 days on-site. Preparation time: 6-12 months (documented procedures, equipment calibration, staff training). Annual surveillance audits required. Cost: €15,000-30,000 initial, €8,000-15,000 annual.

What documentation is required for aerospace components?

Full traceability package: (1) Material certificates (mill certs with chemical analysis), (2) Heat treatment records, (3) First article inspection (FAI) per AS9102, (4) Dimensional inspection reports, (5) NDT reports, (6) Certificate of Conformance (CoC).
