Capabilities

Capabilities in Locating Shaft Production

Precision turning, cylindrical grinding, and multi-axis machining produce shafts with ±0.005 mm concentricity and exceptional surface finish, ensuring every piece meets AS9100, ISO 9001, and NADCAP standards.

Each part undergoes hardness verification, dynamic balancing, runout inspection, and coordinate metrology, as well as batch traceability, FAI documentation, and functional load testing, to confirm alignment for aerospace installations across a wide range of operational temperatures.

FAQ

Frequently Asked Questions

These are our common FAQs. If you need specifics: such as machines, quoting, lead time, shipping, quality process, packaging, or payment, please email info@aerocncparts.com.

Our engineers will reply with clear, detailed information.

Can locating shafts be produced to match an OEM drawing exactly?
Yes, shafts are machined directly from supplied CAD/technical drawings with complete dimensional verification and traceable inspection data.
What balance and runout limits can you guarantee for high-speed assemblies?
Typical runout is held to ≤0.01 mm; dynamic balancing is offered to customer-specified G-levels or RPM ranges.
Are custom surface treatments available for corrosion or wear-critical applications?
Yes, optional finishes, e.g., TiN, hard chrome, and electropolishing, are selectable to meet specific corrosion, wear, or friction requirements.
Do you support low-volume prototypes and rapid validation runs?
Yes, small prototype batches with complete inspection reports and test data are supported before full production.
What documents accompany a shipment for qualification and audit purposes?
Deliverables include CMM inspection reports, material certificates (traceable heat/batch numbers), FAI pack, and any requested process or plating certifications.
