This full-set industrial lens barrel assembly is a complete high-precision optical structural kit tailored for machine vision systems. The full package covers lens body, focus adjustment ring, aperture control ring, sliding sleeve, cam barrel and mounting base. Mainly crafted from high-stability 6061 aluminum alloy with partial brass matching parts, the finished components adopt matte black hard anodizing and clear laser calibration scales, delivering professional optical performance and durable mechanical quality.

Different from ordinary consumer camera lens housings, industrial lens components require far stricter coaxiality, roundness and inner wall smoothness to ensure long-term stable imaging and anti-vibration performance in automated industrial environments. We adopt professional turn-mill composite and 4-axis linkage CNC machining technology to complete all complex structures in one clamping, avoiding cumulative positioning errors from repeated re-fixturing. Raw materials select low-stress aluminum and brass bars to effectively eliminate post-processing deformation, guaranteeing consistent dimensional stability after long-term repeated focusing and adjustment.

The complete manufacturing workflow includes precision bar blanking, CNC rough and finish turning, 4-axis milling, knurling, laser marking, surface treatment and strict quality inspection. CNC turning precisely machines outer circles, inner holes, positioning steps, standard C/CS ports and lens mounting seats, controlling micron-level inner hole coaxiality and end face runout to prevent lens eccentricity and imaging distortion. 4-axis linkage milling accurately fabricates cam oblique curve grooves, straight guide grooves and positioning notches. The high-precision cam curve ensures ultra-smooth focusing operation without jitter or stuttering, which is the core advantage of industrial professional lens barrels.

The outer ring of the focus ring adopts fine anti-slip knurling technology to increase rotational friction for precise manual adjustment. Clear laser marking displays professional optical parameters including f1.8, f2.8, working distance and aperture values, featuring wear-resistant and long-lasting calibration. The surface is finished with matte black hard anodizing to eliminate internal stray light, ghost images and reflection interference, greatly improving industrial imaging clarity. Partial brass matching parts are gold-plated to enhance assembly smoothness and corrosion resistance. All finished parts undergo precision deburring, ultrasonic dust-free cleaning and CMM full-size inspection to meet high-end industrial optical standards.

Our factory excels in solving multiple processing difficulties of thin-wall optical barrels, including cutting deformation, curve groove tolerance deviation and oxidation dimension deviation. We reserve accurate oxidation allowances in advance to ensure final finished dimensions fully meet assembly requirements. As a professional CNC precision machining manufacturer, we provide one-stop services from 3D drawing analysis, process optimization, prototype trial production to batch mass delivery with a stable precision of ±0.01mm.
