| Laser generator |
Model |
Single-mode, multimode, low mode are suitable for thin plate cutting, high-modulus is suitable for thick plate cutting |
| Power |
The cutting performance is decided by the laser power |
| Light path |
Collimating mirror |
The larger collimation, the smaller focusing spot,the higher focused energy, the shorter focal dept,is not suitable for cutting thick plate,usually use F=75mm,F=100mm |
| Focusing lens |
the smaller focusing lens, the larger focusing spot,short of focal depth,is suitable for cutting thin plate,usually use F=150mm,F=200mm |
| Air cock |
Gas mouth shape |
Effect the speed of the cutting point airflow |
| Gas mouth size |
1.0-2.0mm different thickness of plate,choose different size of gas mouth |
| Gas mouth height |
Effect airflow, then effect the final cutting result |
| Auxiliary gas |
Dry,oily degrees |
Effect on laser energy |
| Gas purity |
Oxygen purity 2% lower,cutting speed lower50% |
| Gas flow |
Size of flow,effect the cutting speed and effect on the back |
| Gas pressure |
The pressure, effect cutting speed meter edge effectivness |
| Cutting parameters |
Cutting speed |
The speed, pressure, laser power, all effect the cutting results |
| Height of focus |
Depth of focus determines the work positionof focus on different thickness of the plate |
| Cutting materials |
Thickness of plate |
0.1-12mm thickness plate,affect the efficiency and effectiveness |
| Melting point of material |
melting point,affect the cutting effectiveness |
| Material absorptivity of laser |
The material absorptance of laser ( 1.64um ) |
