Custom CNC Turned Stainless Steel Multi-Step Precision Shaft
This multi-step stainless steel shaft is manufactured by CNC turning and precision grinding. Multiple stepped diameters maintain high concentricity to guarantee stable rotation. It serves as core transmission component widely used in automation actuators, testing equipment and miniature power systems.
This custom stepped shaft is machined from solid stainless steel bar stock. Different outer diameter sections are formed in one CNC turning cycle, followed by precision cylindrical grinding to achieve excellent straightness and surface smoothness. Shoulder steps are designed for positioning and assembly limit. Tiny locking holes or flat cuts can be added according to customer drawings.
At Chenrong Precision, raw material certificates are verified before machining. Our turning and grinding workshop controls runout strictly for multi-step features. After machining, we perform deburring, ultrasonic cleaning and full dimensional inspection. Stainless steel delivers outstanding rigidity and corrosion resistance, keeping consistent performance even under continuous rotating operation.

Q: What maximum length of stepped shaft can you process?
A: We can handle stainless steel stepped shafts up to 600mm in length, subject to diameter and straightness requirements.
Q: Is cylindrical grinding mandatory for this shaft?
A: Not mandatory. If your application does not require ultra-low runout, we can supply parts with only CNC turned finish to reduce cost.
Q: Can you add flat milling or keyway on the shaft?
A: Yes, secondary milling operation is available to add keyways, flat surfaces or anti-rotation features.
Q: What is the maximum runout you can guarantee?
A: We can control total runout down to 0.003mm for ground multi-step shafts.
Q: Can the shaft be heat treated for higher hardness?
A: Yes, heat treatment service can be arranged to improve surface hardness and wear resistance upon request.
