The parameters that affect cutting quality include cutting height, cutting nozzle model, focus position, cutting power, cutting frequency, cutting duty cycle, cutting air pressure, and cutting speed. Hardware conditions include: protective lenses, gas purity, plate quality, focusing and collimating mirrors.
When encountering poor cutting quality, it is recommended to conduct a general inspection first. The main inspection contents and sequence of general inspection are:
1. The height of the laser cutting machine (it is recommended that the actual cutting height be between 0.8~1.2mm). If the actual cutting height is not accurate, calibration is required.
2. Check whether the model and size of the cutting nozzle are used incorrectly. If it is correct, check whether the cutting nozzle is damaged and whether the roundness is normal.
3. It is recommended to use a cutting nozzle with a diameter of 1.0 for optical center inspection. When checking the optical center, it is best to focus between -1 and 1. The light produced in this way is small and easy to observe.
4. Check whether the protective lenses are clean and require no water, oil, or residue. Sometimes, fogging of protective lenses can occur due to weather conditions or too cold air.
5. Check if the focus is set correctly. If it is an autofocus cutting head, be sure to use the mobile app to check if the focus is correct.
6. Modify cutting parameters.
