Verify a Chinese CNC machining supplier before the production decision.
Machine-manufacturer verification and machine-shop qualification are different exercises. This service focuses on whether a machining supplier is a real, suitable, and documentable fit for the part requirements you have.
What we would investigate first.
The exact scope depends on risk, part complexity, and the evidence already available. The questions below are a practical starting point.
Company and factory
Legal identity, address, actual factory versus trader, ownership of equipment, product scope, communication contact, and export history.
Equipment and engineering
Machine models, axis configuration, tooling, probing, CAM, operator/programmer experience, workholding, maintenance, and comparable work.
Inspection and control
Metrology, CMM or equivalent access, calibration, inspection plans, first-article process, traceability, nonconformance, and production records.
A serious review asks for explanations, not only brochures.
- Photos or video that connect the equipment to the actual factory and address
- Exact machine list, relevant models, and which processes are in-house or subcontracted
- Example inspection report with sensitive customer information removed
- Material and heat-treatment traceability process
- Sample-part, first-article, or comparable production evidence where available
- Quality documentation, capacity discussion, packaging, and issue-escalation process
Verification reduces uncertainty; it does not replace your technical acceptance process.
The output should make the next decision clearer: continue to RFQ, request an NDA, run a sample, arrange a call or visit, add an inspection gate, or stop spending time on the supplier.
Important: certification is one input, not a substitute for capability evidence.
Same buyer-side discipline, different evidence.
| Machine supplier | Machining supplier |
|---|---|
| Machine model, components, assembly, controller, acceptance test | Part process, setups, programming, tooling, inspection, repeatability |
| Warranty, installation, manuals, spare parts, export documentation | Material traceability, subcontracted processes, first article, production control |
| Factory identity and manufacturing versus reseller status | Actual shop capability and who will make and inspect the part |
| Machine demo and pre-shipment inspection | Sample or first-article work, inspection reports, and ongoing quality records |
