CNC Supplier Audit Checklist: Evidence Before Capability Claims

Audit the production route for your actual part family, not just the factory tour. Verify objective evidence for process planning, machine and fixture suitability, inspection capability, material traceability, special-process control, nonconformance handling, change control, and capacity.

Read the guide

Reviewed supplier records, each with a source.

A reviewed record has been checked against its source listing and the Chinese business registry, and the holders of its certificates have been read from the listing; certificates are not confirmed with their issuers. Every record links to the page it was extracted from, and shows plainly what the supplier did not declare.
