The parameters that affect the cutting quality are: cutting height, cutting nozzle type, focus position, cutting power, cutting frequency, cutting duty cycle, cutting pressure and cutting speed. Metal Laser Cutting Service hardware conditions include: protective lens, gas purity, plate quality, focusing lens and collimator, etc.
If the fiber laser cutting quality is poor, you are advised to perform a general check.
The main contents and sequence of general inspection are as follows:
1. The cutting height is recommended to be adjusted between 0.8~1.2mm. If the actual cut height is not accurate, calibration is required.
2. Check whether the model and size of the cutting copper nozzle are used improperly. If used correctly, check the copper tip for damage.
3. It is recommended to use a diameter of 1.0 cutting copper nozzle for optical detection. The focus of the optical center detection should be between -1 and 1. The light spot is small and easy to observe.
4, protective lens check whether the protective lens is clean, no water, no oil, no residue. Sometimes, due to weather and climate reasons, the air is too cold and other reasons lead to protective glasses fog.
5. Focus and check whether the focus setting is correct. If the cutting head is auto-focusing, be sure to use the APP to check that the focus is correct.
After the preceding five checks are correct, modify the parameters according to the cutting phenomenon of the fiber laser cutting machine.
