Product Description
CNC Machined Aluminum Alloy Lens Adjustment Ring
Application
Used as a core adjustment component for lens focus and zoom in professional camera lenses, optical inspection equipment, and industrial vision systems. Enables precise axial displacement and positioning of optical lens groups, adapting to high-frequency rotation adjustment conditions.
Widely used in DSLR/mirrorless lenses, industrial vision inspection equipment, and other high-precision optical scenarios.
Material & Performance
Material: 6061-T6 Aluminum Alloy
- Tensile strength ≥310MPa, yield strength ≥276MPa
- Extreme dimensional stability and fatigue resistance
- Lightweight with excellent corrosion resistance
- Reduces lens weight while ensuring long-term optical system accuracy
- Complies with RoHS and REACH environmental standards
Processing Method
Core processing: 5-axis CNC turn-mill composite machining for multi-layer sealing spigots, special-shaped card slots, and precision positioning structures
Auxiliary processing: High-precision drilling, tapping, laser engraving marking, contour chamfering, and deburring
Full CNC programming ensures coaxiality and sealing surface accuracy, suitable for small-batch high-precision customized production
Machining Accuracy & Requirements
| Parameter | Specification |
|---|---|
| Dimensional Tolerance | ±0.01mm |
| Shaft Coaxiality | ≤0.02mm |
| Sealing Surface Flatness | ≤0.03mm |
| Surface Roughness | Ra ≤1.6μm |
| Operating Temperature | -20℃ to 60℃ |
Requirements: Uniform and smooth rotation damping, no jamming or loosening after long-term use, ensuring optical focus accuracy and imaging stability.
Heat Treatment
Process: Solution treatment + artificial aging (T6 condition)
Purpose: Improves material strength and dimensional stability, prevents deformation after long-term rotation use, and ensures accuracy retention and structural reliability of lens adjustment.
Post-treatment
Black anodizing forms a dense, wear-resistant oxide protective layer that significantly enhances surface corrosion and scratch resistance.
The matte black appearance combines non-slip properties with visual recognition, adapting to precise optical equipment operating environments and complying with EU environmental certification requirements.
Quality Control
Full-process closed-loop quality control implemented throughout manufacturing:
- Incoming material spectral inspection
- 100% in-process geometric tolerance inspection
- Final finished product testing (appearance/rotation damping/coaxiality)
- Traceable inspection reports provided for each batch
- Strict compliance with ISO9001 quality system certification
