If delivered CNC components fail to meet your drawing specs, Zhejiang Dream Industry Limited provides a comprehensive compensation policy including free replacement of non-conforming parts, expedited rework, or a full refund for the affected batch based on verified quality inspection reports.
At Zhejiang Dream Industry Limited, precision is managed through an ISO 9001 certified quality system. Standard CNC components maintain tolerances of ±0.1 mm, while high-precision parts achieve tight tolerances of ±0.03 mm. When a dimensional discrepancy is reported, our quality control team reviews the original First Article Inspection (FAI) records and verifies the material certificate to confirm material grade compliance, whether for Stainless Steel 304/316, Aluminum 6061, or Brass C360.
For instance, in our past cooperation cases, such as the CNC machine positioning project involving 65,000 adjustable clamping knobs, strict dimensional consistency was maintained. If any batch fails to meet the specified surface roughness (ranging from Ra 3.2 to Ra 0.8) or tolerance limits, the affected parts are replaced under our quality guarantee. This policy applies across all application scenarios, including medical devices, food processing equipment, and marine systems.
| Deviation Category | Tolerance Range | Compensation / Resolution Action |
|---|---|---|
| Minor Cosmetic / Roughness Deviation | Ra > specified but functional | Surface treatment touch-up or partial credit refund (up to 15%) |
| Non-Critical Dimensional Deviation | Beyond standard ±0.1 mm but fits assembly | Discounted acceptance, local rework compensation, or parts replacement |
| Critical Functional Failure | Beyond precision ±0.03 mm, assembly impossible | 100% free remanufacturing with expedited shipping or full refund |
| Shipping of Replacement Parts | N/A | Express shipping via DHL, UPS, or FedEx covered by the factory |
How long do I have to file a compensation claim for out-of-spec CNC components?
Customers can file a claim within 30 days of receiving the shipment. The claim should include dimensional measurement reports or 2D/3D drawing comparisons.
Who covers the shipping costs for replacement or reworked parts?
Under our quality guarantee, Zhejiang Dream Industry Limited covers all express shipping costs (via DHL, UPS, or FedEx) for approved replacement parts.
What documentation is required to initiate a compensation process?
We require a basic quality discrepancy report, clear photographs of the out-of-spec dimensions measured with calibrated instruments, and the corresponding drawing specification reference.
To prevent out-of-spec issues, we implement 23 quality inspection steps during the CNC turning and milling processes. Our factory supports OEM and ODM manufacturing with flexible MOQ options starting at 50 pieces for custom CNC components. By conducting rigorous pre-shipment inspections, we maintain a defect rate below 0.3%. Technical Support: 86-15868979792
