When regular design meet precision CNC technology, a pair of eyeglass aethetics is redefined - behind this, 5-axis machining technology is reshaping the craftsmanship of eyewear manufacturing. The regular processing of traditional eyeglass frames relies on manual carving or simple molds, which are not only inefficient and limited to simple designs, but also have a precision error of over 0.1mm for complex curves and three-dimensional designs. In contrast, 5-axis CNC machines realize 360° accurate processing of frames through the coordination of X/Y/Z axes and dual rotary axes, offering designers more design possibilities.
Our newly launched Cat Eye Acetate Glasses features 3D dimension from outer surface and inner surface , both formed by 5-axis equipment with a precision of 0.015mm. It not only present the original design details but also avoids defects caused by multi-processing.
Based on recent production status, we have summarized the following process parameter comparison table of eyeglass frames processed by 5-axis machining vs traditional craftsmanship:
| Process | Core Parameters of 5-axis Machining | Traditional Craftsmanship (Disadvantages) | Application Value |
|---|---|---|---|
| Material Compatibility | Acetate/TR90/Titanium Alloy: Rotating speed 8000-12000r/min | Only compatible with single material; Rotating speed ≤3000r/min | Supports fancy designs for multiple materials, adapting to frames of different styles |
| Precision Control | Positioning accuracy ±0.015mm; Repeatability accuracy ±0.01mm | Precision error ≥0.1mm | Zero deviation for complex textures/curves, restoring design details perfectly |
| Fancy Texture Processing | Embossing/Hollowing/Gradient: Feed rate 50-80mm/min | Only supports simple flat textures; Feed rate ≤20mm/min | Achieves highly recognizable artistic effects for frames |
| Processing Cycle | Single frame: 1-2 mins/piece | Single frame: 30-60 mins/piece | Improves small-batch customization efficiency by over 60% |
| Edge Treatment | Chamfer radius 0.2-0.5mm; Integrated automatic polishing | Manual chamfering with error ≥0.5mm | Enhances wearing comfort and reduces wear |
| Defect Rate Control | Finished product defect rate ≤0.1% | Defect rate ≥5% | Reduces production costs and ensures consistent batch quality |

Currently, the global eyewear market exceeds 140 billion US dollars. Gen Z's demand for personalization plus high quality drives big requirement of 5-axis machining technology: among domestic mid-to-high-end eyewear brands in 2025, the proportion of products adopting 5-axis craftsmanship has risen from 10% in 2020 to 40%, and the premium sunglass with fancy textures can reach 2-3 times that of ordinary ones.
