If delivered CNC components do not match your approved drawings, our compensation policy guarantees immediate corrective action. Under our quality assurance framework, Zhejiang Dream Industry Limited provides free replacement, precision re-machining, or full refunds for verified non-conforming parts. We resolve all dimensional discrepancies within our strict ISO 9001 quality management guidelines to eliminate customer downtime.
At Zhejiang Dream Industry Limited, precision is maintained through a robust quality control system. Our manufacturing facility operates under the ISO 9001 standard (Certification No. ZT-Q-24120011S), ensuring that every CNC component is machined to exact drawing specifications. If a deviation occurs, we initiate our structured quality issue response protocol to analyze the defect and implement correction measures.
Our technical team uses advanced inspection equipment to verify dimensions against 2D/3D design files (supporting PDF, CAD, DWG, DXF, STEP, IGS, and STP formats). If the delivered parts do not match the approved drawings, customers must provide inspection reports or dimensional data. Once verified, we prioritize production rescheduling to ship replacement components. For example, in our cooperation cases, such as the supply of 65,000 adjustable clamping knobs for CNC machines in Italy or marine-grade handwheels for Norway, strict compliance with dimensional drawings resulted in zero-defect delivery and long-term customer trust.

|---|---|---|
| Dimensional Tolerance | ±0.1 mm | ±0.03 mm |
| Surface Roughness (Ra) | Ra 3.2 to Ra 1.6 | Ra 0.8 or Mirror Polishing |
| Discrepancy Resolution | Rework or replacement within 7–15 days | Priority rapid prototyping & express replacement |
| Verification Methods | Standard dimensional inspection | First Article Inspection (FAI) & full 23-step inspection |
Q1: What files do you accept to verify drawing compliance?
A1: We accept major 2D and 3D technical files for drawing verification, including PDF, CAD, DWG, DXF, STEP, IGS, and STP formats. All manufacturing and post-delivery inspections are strictly benchmarked against these files.
Q2: How long does it take to receive replacement CNC components?
A2: Once a dimensional mismatch is confirmed, standard replacement orders are processed and shipped within 7 to 15 days. For urgent industrial applications, we expedite manufacturing to minimize client downtime.
Q3: Do you provide material certification with the delivered parts?
A3: Yes, we provide material certificates, RoHS compliance, and REACH compliance data upon request to verify that both the material grades (such as 304/316L stainless steel, 6061 aluminum, or engineering plastics) and mechanical properties meet your specifications.
To ensure your custom CNC components perfectly match your drawings, we recommend utilizing our First Article Inspection (FAI) service before initiating mass production. Zhejiang Dream Industry Limited supports flexible business models, including OEM/ODM manufacturing, custom CNC machining, and prototype sampling (1–10 pieces). Our ISO 9001 certified quality control process, combined with automated CNC production, ensures stable quality and minimizes structural deviations. Technical Support: 86-15868979792
