5 Steps to Bulletproof Remote QA for CNC Machining in China

Performing remote QA audits for CNC machining in China starts with demanding a First Article Inspection report and full CMM data before full production. This checkpoint verifies every critical dimension on the first part and prevents batch-wide issues. Outline documentation needs clearly at the RFQ stage. Lock in FAI and CMM requirements so suppliers quote with inspection costs included. Require a ballooned drawing with numbered dimensions and raw CMM outputs matched to each callout. Hold shipment until you review and approve reports. Request in-process photos or video for new suppliers and sample CMM data later in the run to catch tool wear and drift. Track supplier performance over time for long-term quality. This approach saves time and money by catching problems early in the supply chain. It creates a repeatable QA system even when you can’t visit the factory in person.
