Custom CNC Turn‑Mill Machined Precision Alloy Steel Step Shaft for Automation Transmission Equipment
This custom stepped shaft is manufactured by CNC turn‑mill composite machining. Multi‑step outer diameters, keyway slots and precision center holes are completed within single clamping. High concentricity and tight dimensional tolerance deliver stable power transmission performance. Alloy steel material provides outstanding wear resistance for long‑time continuous‑running automation machinery.
Stepped shaft acts as core rotating transmission component for automated industrial devices. Our turn‑mill process realizes outer turning, keyway milling, chamfering and deburring in one‑setup, avoiding cumulative positioning deviation caused by repeated re‑clamping. Our team performs DFM assessment before production. Run‑out, dimension and surface finish will be fully inspected for each batch. Step diameters, keyway dimensions and overall length can be customized as per customer drawings. Quenching and tempering heat treatment is optional to improve mechanical hardness and anti‑wear property.

Q1: Can you add heat treatment to this alloy steel step shaft?
A1: Yes, quenching & tempering, surface hardening are available upon request.
Q2: What concentricity can you achieve for multi‑step shaft?
A2: We can control concentricity within 0.005mm according to drawing requirements.
Q3: Can I customize the number of steps and keyway specifications?
A3: Fully customizable, send us your technical drawing for evaluation and quotation.
Q4: What file types do you accept for drawing review?
A4: We accept 2D CAD / PDF and 3D STEP / IGES files.
Q5: What is your lead time for shaft prototype samples?
A5: Normally 7‑10 working days for prototype samples, depends on complexity and heat‑treatment requirement.
