Custom CNC Machined Spindle Shaft Assembly High Precision

Custom CNC Machined Spindle Shaft Assembly High Precision Industrial Automation Machine Tool Core Component

This machine tool spindle shaft assembly is manufactured by multi‑axis CNC turning milling and grinding composite process for industrial automation machine equipment. The part contains multi‑stage stepped shaft, flange mounting holes, inner bore and precision fitting surfaces. Superimposed high‑precision fitting surfaces require strict concentricity and roundness control. Composite machining and fine grinding process eliminate secondary clamping errors to guarantee high-speed rotating performance.

We support diversified raw material options to satisfy high‑speed, heavy‑load and anti‑wear working requirements. Every spindle shaft undergoes strict run‑out and dimensional inspection before delivery.
