The emergence of high-power laser cutting machines provides better solutions and more possibilities for sheet metal processing, especially for the improvement of cutting speed and cutting quality. However, some problems will inevitably occur during the use of high-power laser cutting machines, such as poor cutting. Let Leapion Laser share how to solve the problem of using high-power laser cutting machine.
In the process of using a high-power laser cutting machine, if the cutting effect is found to be poor, we must first investigate the following reasons:
1. Check that all lenses in the laser head are not polluted and are clean;
2. Check that the water temperature of the water tank is normal and there is no condensation on the laser;
3. Check the cutting gas purity is excellent, the gas path is smooth, and there is no gas leakage.
possible reason:
1. The nozzle is incorrectly selected and the nozzle is too large;
2. The air pressure is set incorrectly, and the air pressure is set too high, which will cause overburning and streaks;
3. The cutting speed is wrong, and the cutting speed is too slow or too fast to cause sufficient overburning.
Solution:
1. Replace the nozzle, replace the nozzle with a small diameter, such as 16mm carbon steel bright surface cutting, you can choose high-speed nozzle D1.4mm; 20mm carbon steel bright surface can choose high-speed nozzle D1.6mm;
2. Reduce the cutting air pressure and improve the cutting quality of the end face;
3. Adjust the cutting speed so that the power matches the cutting speed properly.
1. The nozzle is too small and the cutting focus is not matched;
2. The air pressure is too small or too high, and the cutting speed is too fast;
3. The material of the plate is poor, and the quality of the plate is not good. It is difficult to remove the tumor slag with a small nozzle.
Solution:
1. Replace the large-caliber nozzle and adjust the focusing focus to a suitable position;
2. Increase or decrease the air pressure until the air flow is appropriate;
3. Choose good plates.
possible reason:
1. The nozzle diameter is too small to meet the processing requirements;
2. If the negative defocus does not match, you should increase the negative defocus and adjust the appropriate position;
3. The air pressure is too small, resulting in burrs on the bottom and unable to fully cut.
Solution:
1. Using large-caliber nozzles can increase air flow;
2. Increase the negative defocus to make the cutting section reach the bottom position;
3. Increasing the air pressure can reduce the bottom burr.
