High-Precision CNC Machined Automotive Ball Screw Nut Components

1. Material: Carbon steel, stainless steel, aluminum alloy, etc.
2. Shape: A stepped cylindrical component featuring distinct knurling or anti-slip texturing on the outer surface; symmetrical top and bottom sections with a transitional cylindrical segment in the middle.
3. Size Range: Diameter approx. 8mm–25mm; height approx. 10mm–30mm.
4. Internal Design: Features an internal coaxial threaded bore designed for bolt fastening or shaft mating, providing high-strength connection and positioning capabilities.
5. Surface Treatment: Deburring; light polishing or barrel finishing; some batches may undergo anti-rust treatment (e.g., black oxide or phosphating) to enhance corrosion resistance and visual uniformity.
6. Manufacturing Process: CNC turning, external knurling, internal hole tapping/threading, secondary deburring and cleaning, and final dimensional inspection (via CMM or optical comparator).
