Why Choose Laser Cutting?
Compared with traditional mechanical cutting, laser cutting offers significant advantages.
| Comparison | Laser Cutting | Traditional Mechanical Cutting |
| Processing Method | Non-contact laser processing with no mechanical stress | Contact cutting with mechanical stress |
| Cutting Quality | No edge chipping, minimal micro-cracks, high yield | Edge chipping and micro-cracks are common |
| Precision | Narrow kerf (20–50 μm), small heat affected zone | Wider kerf, accuracy affected by tool wear |
| Flexibility | CAD file import, no tool replacement required | Frequent tool replacement, less suitable for multiple product types |
| Efficiency | High cutting speed and continuous operation | Grinding wheel replacement reduces productivity |
