Custom CNC Turn-Machined Stainless Steel Drive Shaft

Product Summary

This custom stainless steel drive shaft is produced by CNC turn-mill combined machining. It integrates multi-stage shoulder diameters, precision step surfaces and spiral milling slot on one single part. The shaft maintains excellent concentricity and surface smoothness after finishing, suitable for power transmission and rotary movement in automated machinery. We support custom dimension, slot profile and tolerance according to your CAD drawings.

Key Features

• Turn-mill composite machining, complete turning and milling features in one clamping to ensure high concentricity and coaxiality
• Multi-step shoulder structure + spiral milling slot design, ensuring stable rotation and precise transmission
• High-quality stainless steel material, featuring high hardness, wear resistance and excellent corrosion resistance
• Fine polished surface with low friction coefficient, reducing mechanical operation loss
• Supports 1PC prototype verification and large-scale mass production with stable batch consistency

FAQ

Q1: Can you customize the diameter, length and spiral slot shape of this drive shaft?

A1: Yes. All dimensions, shoulder layout and spiral slot geometry can be fully customized based on your 2D & 3D drawings. Our team provides free DFM optimization before production.

Q2: What stainless steel grades can be used for this rotary shaft?

A2: We normally use 304 and 316L stainless steel. 316L delivers better anti-corrosion performance for humid, outdoor or chemical working environments.

Q3: Can we achieve tighter tolerance for shaft runout?

A3: Yes. We can control runout tolerance as low as 0.005 mm for high-precision rotary requirements, and provide complete dimension inspection reports.
