Cylindrical structural shaft for **optical instruments and automation modules**

1.Application

Cylindrical structural shaft for optical instruments and automation modules. External thread for locking connection, side cut‑outs and counter‑bore holes for component mounting. Provides positioning support and axial assembly.

2.Material & Performance

6061‑T6 Aluminum Alloy. Light‑weight, good machinability, sufficient structural strength. RoHS & REACH compliant.

3.Processing

Turn‑mill composite machining. Machine OD, external thread, inner bore, side windows and mounting holes. Edge radiusing & full deburring. Strictly control coaxiality and thread tolerance.

4.Accuracy & Requirement

Tolerance ±0.015mm, coaxiality ≤0.02mm, thread class 6H, hole position ≤0.02mm, Ra≤1.6μm. Operating temp‑20℃~+80℃. Control assembly torque, protect thread and OD surface from impact and scratch.

5.Heat Treatment

T6 solution & artificial aging, relieve machining stress, ensure dimensional stability of shaft part.

6.Post‑treatment

Black hard anodizing. Improved wear & corrosion resistance, matte black finish.

7.Quality Control

ISO9001 system. Spectroscopic incoming check; coaxiality & thread inspection; CMM dimension test; visual check for anodizing surface; pre‑shipment cleaning. Industrial Packaging: Individual PE film + thread protective sleeve, EPE foam separation, anti‑static carton. Pallet packing for bulk orders to avoid thread damage.
