High-power laser cutting, known for its rapid processing speed and ability to handle thick metal sheets, has increasingly become a staple in metalworking industries. Despite its advantages, users often encounter specific technical challenges that can impact the quality of the cut. This article identifies three common issues in high-power metal sheet laser cutting and provides practical solutions for each, enhancing overall cutting efficiency.
The adoption of high-power laser cutting in the metalworking sector has grown due to its fast cutting speeds and high processing efficiency. However, as with any advanced technology, certain technical challenges can arise during operation. Addressing these effectively is crucial to maintain cutting quality and efficiency.
Common Technical Challenges and Solutions:
1. Issue: Nodule Formation at the Bottom of the Cut
1.1 Inappropriate nozzle size leading to mismatched cutting focus.
1.2 Incorrect air pressure settings, either too high or too low.
1.3 Poor quality of the metal sheet being cut.
1.1 Use a larger diameter nozzle and adjust the focus to the appropriate position.
1.2 Modify air pressure settings to achieve an optimal balance.
1.3 Replace the metal sheet with one of better quality.
2. Issue: Striation on the Cutting Surface
2.1 Incorrect nozzle selection with too large an aperture.
2.2 Excessive air pressure leading to overburn and striation.
2.3 Improper cutting speed, either too fast or too slow.
2.1 Switch to a nozzle with a smaller diameter.
2.2 Adjust air pressure to a suitable level for cutting.
2.3 Fine-tune the cutting speed to ensure it matches the power output.
3. Issue: Burrs at the Bottom of the Cutting Surface
3.1 Inadequately sized nozzle, failing to meet the hardness and density requirements of the workpiece.
3.2 Incorrect negative focus setting.
3.3 Air pressure too low to achieve complete cutting.
3.1 Opt for a larger diameter nozzle to increase cutting flow.
3.2 Adjust the negative focus to ensure complete penetration.
3.3 Increase air pressure to ensure thorough and clean cutting.
Additional Troubleshooting Steps
Ensure all lenses inside the laser head are clean and free of contaminants.
Check the water tank temperature and for any condensation on the laser.
Inspect cutting purity and air flow to rule out any leakages.
