Project Challenge

Control straightness, concentricity, and cross-hole position on a slim turned shaft.

Our Solution

We used staged turning, supported the shaft during finishing, and drilled the cross hole from a controlled fixture to keep the position repeatable.

Quality Check

Diameter, runout, cross-hole position, end features, and surface finish were checked before shipment.

Project Overview

This precision linkage shaft features stepped diameters, a machined head, and a cross hole. Its slim geometry required careful control of straightness, concentricity, and surface finish.

Manufacturing Approach

We used staged CNC turning, supported the shaft during finishing, and drilled the cross hole in a controlled fixture to maintain repeatable position.

Quality Assurance

Diameter, runout, cross-hole position, end features, and polished surface condition were checked before shipment.
