Efficiently solving three major challenges in fiber laser cutting machine using
High power fiber laser cutting machine using machines have gained widespread market recognition once they were launched due to their irreplaceable advantages such as large cutting width, fast cutting speed, and the ability to cut thicker plates. However, due to the fact that high-power fiber laser cutting machine using technology is still in its early stages of popularization, although staff from fiber laser cutting machine using machine manufacturers have provided systematic training to enterprise operators during equipment delivery and training, some operators still lack proficiency in the skills of high-power fiber laser cutting machine using.
Based on the summary of technical engineers and common customer issues, the following solutions to the difficulties in high-power fiber laser cutting machine using process are summarized.
When poor cutting effect is found, the following situations should be checked first: 1. All lenses in the laser head are not contaminated and are clean. 2. The water temperature in the water tank is normal and there is no condensation on the laser. 3. The cutting gas purity is excellent, the gas path is smooth, and there is no leakage
1： Cutting with stripes: 1. Wrong nozzle selection, nozzle too large. 2. Incorrect air pressure setting, excessive air pressure causing excessive burning with stripes. 3. Incorrect cutting speed, too slow or too fast cutting speed can also cause sufficient burning. Solution: 1. Replace the nozzle, replace the nozzle with a smaller diameter, such as 16mm carbon steel bright cutting, and choose high-speed nozzle D1.4; 20mm carbon steel bright surface can be selected with high-speed nozzle D1.62. Reduce cutting pressure to improve end cutting quality. 3. Adjust cutting speed to match power with cutting speed appropriately
2： There are lumps at the bottom. 1. The nozzle is too small and the cutting focus does not match. 2. The air pressure is too small or too large, 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 lumps with small nozzles. Solution: 1. Replace the large-diameter nozzle and adjust the focus to the appropriate position. 2. Increase or decrease the air pressure until the air flow rate is appropriate. 3. Choose a good plate
3： There are burrs at the bottom. 1. The nozzle diameter is too small to meet the processing requirements. 2. The negative defocus does not match, so the negative defocus should be increased and adjusted to the appropriate position. 3. The air pressure is too small, which causes burrs at the bottom and cannot be fully cut. Solution: 1. Selecting a large diameter nozzle can increase the air flow rate. 2. Increasing the negative defocus to make the cutting section reach the bottom position. 3. Increasing the air pressure can reduce the burrs at the bottom.
