Multi-Step Optical Lens Barrel 6061 Aluminum Combined Turn-Mill Machined 0.01mm

Our multi‑step optical lens barrel is a high‑precision rotary optical component made of 6061 aluminum alloy, produced in our CNC factory by composite CNC turning plus partial side milling operations.

The manufacturing workflow begins with aluminum bar stock cutting. CNC lathe rough‑machines inner and outer profiles to form multi‑step annular grooves. Fine turning processes inner and outer circles, strictly controlling inner‑hole coaxiality and end‑face flatness to ensure perfect concentric assembly of optical lenses. Radial tiny holes and positioning notches are completed by side milling. High‑gloss turning delivers burr‑free surfaces. Hard anodizing surface treatment is optional for enhanced wear resistance and anti‑corrosion performance.

This part faces critical manufacturing challenges. Multi‑step features require tight dimensional tolerances. Large length‑to‑diameter ratio of inner bore makes coaxiality hard to maintain. Annular grooves must keep uniform depth, and tiny positioning holes demand high positional accuracy. Any eccentricity will directly impair optical imaging performance.

As a trusted CNC supplier, we provide full‑chain services: 3D drawing review, process planning, prototype trial‑run and mass‑volume finished‑parts delivery. Every tool‑path reflects our pursuit of precision manufacturing. Our machining accuracy reaches ±0.01 mm. We undertake custom non‑standard aluminum parts and complex cavity components for 3‑axis & 5‑axis CNC machining. Prototype, small‑batch and large‑volume orders are all welcome for your custom quote.

Our manufacturing capability covers a wide range of industries: consumer electronics,industrial automation,semiconductor & vacuum equipment,medical devices,new‑energy automotive,aerospace & UAV,optoelectronics,telecommunication hardware,robotic equipment and precision instrumentation. We can produce various precision mechanical components strictly according to customer drawings or samples.
