Why Are There Streaks on the Surface After Laser Cutting?

Cause:

1. The nozzle selection is wrong, and the nozzle is too large.

2. The air pressure is not set correctly. If the air pressure is set too high, there will be streaks after overburning.

3. The cutting speed is wrong, too slow or too fast will cause full overburning.

Solution:

1. Replace the nozzle with a small diameter. For example, for 16mm carbon steel bright surface cutting, you can choose high-speed nozzle D1.4; for 20mm carbon steel bright surface, you can choose high-speed touch nozzle D1.6.

2. Reduce the cutting air pressure to improve the cutting quality of the end face.

3. Adjust the cutting speed, and the power and cutting speed match properly.
