Etching - Controlled ablation
Laser engraving is carried out by removing material layer by layer to obtain a 2D or 3D effect on all material types.
The characteristics of the etching - controlled ablation process:
Benefits
- Controlled ablation up to a few μm depth
- 3D part machining
Performance
- Roughness less than a few μm
- Tolerance of a few μm
- Accuracy of a few μm
Throughput
Variable depending on the material and the pulse duration: on the order of a few mm3.min-1
Laser workstation
- IR, green or UV laser
- Femtosecond to nanoscale pulse
- Scanning systems
Condition surface
Final surface roughness up to 0.5 μm
Process sheet
Areas of application
- Texturing of injection moulds
- Watchmaking
- Stamping tools
