Precision Optical Lens Base CNC Machined from 6061 Aluminum Alloy with Micron

The industrial camera lens mount base is a core precision carrier component for machine vision modules, custom CNC machined from high-quality 6061 aluminum alloy. Serving as the fixed support for industrial lenses and photosensitive chips, this optical base ensures precise positioning and stable assembly of the entire imaging system, which directly determines the clarity, accuracy and distortion performance of machine vision inspection.

Manufactured by professional 3-axis and 4-axis CNC milling, the base adopts one-piece integral forming technology without splicing or assembly gaps. We select low-stress 6061 aluminum plate as raw material, featuring excellent cutting performance and minimal deformation, perfectly suitable for high-precision optical structural parts processing. The complete production process includes plate blanking, rough milling cavity and outline, stress relief aging, finish milling positioning holes, counterbore holes and adjustable grooves, precision deburring and ultrasonic dust-free cleaning. Stress relief aging effectively eliminates internal material stress to avoid long-term dimensional deformation.

The product integrates multiple high-precision structural features, including square outer contour, lens positioning round holes, mounting counterbores, clamping grooves and long strip focusing adjustment slots. The long adjustable groove allows precise front and back fine-tuning of the lens to achieve accurate focusing for different detection distances. The core technical indicator lies in the micron-level verticality between the lens positioning hole and the bottom reference surface, as well as ultra-high flatness. Strict precision control prevents optical axis tilt, effectively avoiding imaging offset, distortion and blurry detection results.

This part faces prominent machining difficulties in thin-wall square cavity processing. The thin-walled structure is prone to tool vibration and edge collapse during milling. We optimize tool path and adopt low-speed low-feed cutting parameters to ensure complete and smooth cavity walls without burrs or tool marks. All hole position tolerance and coaxiality are guaranteed by one-time clamping machining to eliminate cumulative positioning errors from repeated clamping. The inner cavity surface is finely processed with no visible tool traces, reserving perfect conditions for subsequent matte black anti-reflection anodizing to suppress stray light interference.
