High Wear‑Resistant | High Concentricity | Customizable | CNC Turn‑Mill Parts Alloy Steel Step Shaft for Automation Transmission

Custom CNC Turn‑Mill Machined Precision Alloy Steel Step Shaft for Automation Transmission Equipment

Quick detail

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.

Product description

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.
