High Precision CNC Parts
Achieving a micron-level tolerance is a challenge that most shops shy away from, but at our Hangzhou facility, it is our daily standard. For over 11 years, we have specialized in the manufacture of High precision CNC parts that serve as the critical "heart" of medical instruments and aerospace assemblies. We understand that in these industries, a deviation of 0.005mm isn't just a defect; it's a failure point. Our workshop is equipped with high-performance machining centers capable of maintaining a spindle runout of less than 0.001mm. This extreme stability allowed us to recently complete a project for a titanium surgical implant component where we held a surface roughness of Ra 0.1μm across a complex curved geometry, a feat that secured us a long-term partnership with a leading European medical technology group.
When you partner with us for High precision CNC parts, you are accessing a technical team that understands material behavior at a granular level. We don't just "cut to print"; we perform stress-relief cycles and utilize climate-controlled machining environments to ensure that the High precision CNC parts remain dimensionally stable long after they leave our factory. Our ISO 9001:2015 certified quality lab is stocked with CMMs and laser interferometers, ensuring that every feature-from a 0.5mm bore to a complex 3D surface-is verified against your CAD data. We provide the expertise and the advanced technology needed to turn your most challenging designs into functional reality, ensuring your high-end equipment performs flawlessly in the field.

Customization Capability
We offer full OEM/ODM services for complex parts. Our engineering team can assist in optimizing your designs for Swiss-type or 5-axis machining to reduce costs without compromising performance. We support a wide range of exotic materials and provide specialized surface treatments like electropolishing and passivating for medical-grade requirements.
Packaging & Logistics
Precision parts are treated with the utmost care. We use vacuum-sealed anti-static bags and individual compartment foam trays to prevent any surface contact during transit. We offer EXW, FOB, and DDP terms, leveraging our 11 years of export experience to ensure your critical components arrive safely at your facility.
FAQ
Q: What is the tightest tolerance you can hold on a production run?
A: For critical dimensions, we can consistently maintain a tolerance of ±0.002mm on our high-end CNC centers, backed by 100% CMM inspection.
Q: Do you provide a full inspection report with each shipment?
A: Yes, every batch includes a comprehensive dimensional report, material certificate, and, if required, a surface finish analysis report.
