For beginners who just contact the optical fiber laser cutting machine, they encounter the trouble of poor cutting quality. How to adjust the machine in the face of numerous parameters? Let’s look at the solution!
The parameters affecting cutting quality mainly include: cutting height, cutting nozzle model, focusing position, cutting power, cutting frequency, cutting duty cycle, cutting pressure and cutting speed. Hardware conditions include: protective mirror, gas purity, sheet metal quality, focusing mirror and collimating mirror.
If the cutting quality is poor, it is recommended to conduct routine inspection on the metal fiber cutting machine first. The main inspection contents and commands are:
Cutting height
The actual cutting height is recommended to be 0.8-1.2mm. If not, calibration is required.
Nozzle inspection
Check whether the nozzle model and size are correct. If it is correct, check whether the cutting nozzle is damaged or the roundness is normal.
Optical center
It is recommended to use a cutting torch with a diameter of 1.0mm for optical inspection. When checking the optical center, the focus should preferably be between – 1 and 1mm. The resulting light spot is small and easy to observe.
Protective goggles
Check whether the protective mirror is clean and whether there is water, oil and slag. Sometimes the lens fogs due to weather or cold auxiliary air.
focus
Check that the focus is set correctly. If it is an auto focusing cutting head, make sure to check whether the focus is correct.
After checking the above 5 items, if there is no problem, modify the parameters according to the cutting effect.
