FEELTEK has specialized in 3D dynamic focusing laser technology for 12 years, partnering closely with global laser system integrators to deliver tailor-made optical scanning solutions for intricate precision manufacturing. FEELTEK FR20-F 3D dynamic focus system stands as a proven high-performance choice for fiber laser processing of delicate curved components, as demonstrated in the wearable electronics.
Project Background:
Watch Knob diameter: 5mm
Laser device using : IPG 50W
Scanhead: FEELTEK FR20-F 3D scanhead
Working field selection：100*100mm
Extra support: 360-degree rotating shaft
Core challenge:
Full 360° rotary marking is required for flawless continuous textures on curved surfacesVarying focal lengths on curved parts lead to inconsistent engraving depth, burrs and high reject rates while with traditional laser processing.
FEELTEK Solutions:
Equipped with real-time 3D dynamic focusing algorithm that syncs with rotary axis movement; it auto modifies Z-axis focus based on imported 3D model files.
Guarantees consistent engraving depth across all curved surfaces of watch knobs, avoiding uneven carving defects
(shallow or excessive grooves) that damage premium watch appearance.
Ultra-miniature work pieces require custom jigs to firmly fix central spindles.
Here is a detailed processing demonstration video shows the full workflow.
