FAQs:

Q: What is special about the machining process of the step transition area? How is structural strength guaranteed?

A: The step transition area employs smooth radius or taper processing​ instead of abrupt right-angle cuts. This process effectively eliminates stress concentration points, significantly enhancing the overall torsional rigidity and push stability. The tube body is made from medical-grade high-hardness stainless steel or titanium alloy, and undergoes precision cold drawing or grinding, maintaining structural integrity even under high-frequency dynamic operations, eliminating risks of fracture or permanent deformation.

Q: How is the dimensional tolerance of this product controlled? Can it meet high-precision instrument assembly requirements?

A: Our Step-Down Tubes are manufactured using advanced precision CNC machining equipment, with key dimensions (such as each stage’s outer diameter, inner diameter, and step length) controlled within a tolerance of ±0.01mm (10 microns). This micron-level precision ensures perfect fit in high-precision instruments (e.g., endoscopes, surgical robot end-effectors), achieving seamless docking and smooth instrument movement.

Q: Can the size and shape of the step-down tube be customized according to the customer’s specific instrument structure?

A: Yes, we provide full customization services. Simply provide us with drawings or samples, and we can accurately replicate step-down tubes with any number of steps, any diameter difference, or any transition curve. We can also accommodate non-standard materials, special tolerances, or surface functional coatings, offering a one-stop solution for your instrument R&D.
