Fiber laser cutting machines are widely used in metal processing due to their high precision and efficiency. However, some common problems may occur during operation, affecting cutting quality.
This article explains typical issues and how to solve them.
1. Incomplete Cutting
Problem:
The material is not fully cut through.
Possible causes:
- Insufficient laser power
- Cutting speed too fast
- Incorrect focus position
Solutions:
- Increase laser power
- Reduce cutting speed
- Adjust focus correctly
2. Rough or Burnt Edges
Problem:
Edges are rough or show burn marks.
Possible causes:
- Excessive laser power
- Improper assist gas
- Wrong speed settings
Solutions:
- Optimize power and speed
- Use nitrogen for stainless steel
- Maintain stable gas pressure
3. Excessive Burr Formation
Problem:
Burrs appear on the cutting edge.
Possible causes:
- Low gas pressure
- Damaged nozzle
- Incorrect focus
Solutions:
- Increase gas pressure
- Replace nozzle
- Adjust focus position
4. Machine Instability
Problem:
Cutting performance is unstable.
Possible causes:
- Voltage fluctuation
- Dirty lenses
- Lack of maintenance
Solutions:
- Use voltage stabilizer
- Clean optical parts
- Perform regular maintenance
By optimizing machine parameters and maintaining equipment properly, cutting quality can be significantly improved.
