FAQs:

Q: What is the machining accuracy of this product?

A: With Swiss-type CNC machining, dimensional accuracy can reach ±0.01mm, and geometric tolerances (e.g., concentricity, perpendicularity) are controlled within ±0.005mm, meeting precision transmission/connection needs.

Q: Can the material be customized, e.g., to titanium alloy?

A: Yes. Besides 316L/304 stainless steel, customization to titanium alloy (e.g., TC4), aluminum alloy, etc., is available. Feasibility will be evaluated based on application scenarios.

Q: Is the friction of the knurled part sufficient? Will it slip?

A: The knurling angle (typically 15°-30°) is optimized for large contact area and strong bite, preventing slippage during manual operation. For higher friction, deeper knurling or increased density can be customized.

Q: How to ensure the positional accuracy of the side holes?

A: During Swiss machining, side holes and main holes/outer diameters are processed synchronously or via multi-axis linkage, with positional tolerance controlled within ±0.02mm to ensure accurate relative positioning to the datum.
