Precision Linkage Shaft
A slender steel shaft with stepped diameters, a machined head and a transverse hole. CNC turning and drilling bring these features together around a controlled shaft axis.

The details that determine the fit.
The long body is only part of the job. The shoulders, head and cross hole must also stay in the right relationship to the shaft axis.
- Stepped diameters & shoulders
- The turned sections locate mating components. Diameter, shoulder position and straightness are reviewed together against the drawing.
- Machined head & transverse hole
- The wider head creates a connection feature. Hole location and its relationship to the turned body need a controlled reference during the secondary operation.
- Relief grooves & finished edges
- Narrow grooves and diameter transitions remain clearly defined. Deburring must remove sharp edges without damaging the functional surfaces.
Plan the sequence around the shaft.
A long, slim part needs more than a final finishing pass. Our approach controls material removal, support and references before the cross hole is machined.
-
Turn in stages
Remove stock progressively to reduce deflection. Support the slender body during finishing and maintain consistent references for the stepped diameters.
-
Locate the connection features
Complete the head and machine the transverse hole in a controlled setup, keeping its position tied to the shaft axis and drawing datums.
-
Deburr, polish & protect
Verify dimensions before final finishing. Review the hole entry and exit, clean the polished surfaces and protect the parts during handling and packing.
A batch has to repeat the same fit.
The workshop tray shows related shaft components in quantity, including slender turned bodies, rounded heads and drilled features. This is the production context behind the individual part view.
For repeat shaft work, we focus on consistent diameters, hole positions and edge condition, with checks tied to the approved drawing.
The rounded-head components shown here are a related geometry, rather than the exact faceted-head shaft pictured above.
Made with the next assembly in mind.
A shaft works with neighbouring brackets, pivots and connection points. These mechanism and joystick views give application context: mating diameters, hole alignment and shoulder positions matter beyond the individual machined part.
Check the geometry.
Then check the finish.
A polished appearance is only one part of acceptance. The inspection plan follows the functional dimensions and feature relationships on the drawing.

Shaft geometry
Critical diameters, straightness, runout and concentricity are reviewed alongside shoulder and head dimensions.
-
Cross-hole position & edges
Check the hole location against the specified references, and review both entry and exit for burrs.
-
Surface condition & packing
Review polishing consistency, scratches and handling marks. Protect finished surfaces before the parts are packed.
