When the cutting quality of the fiber maszyna tnąca laserem is not good, it is recommended to perform a general inspection first. The inspection as follows:
It is recommended that the actual cutting height is between 0.8~1.2mm, if the actual cutting height is not accurate, calibration is required;
Check whether the model and size of the cutting nozzle are wrong, check whether the cutting nozzle is damaged and whether the roundness is normal;
It is recommended to use a cutting nozzle with a diameter of 1.0 for optical center inspection. The focus is between -1 and 1, so that the light spot is small and easy to observe;
Protect the lens
Check whether the lens is clean, free of water, oil, and residue. Sometimes, the protective lens may be fogged due to weather or auxiliary gas;
1. Cutting stainless steel dross: There are many types of dross. If it is only corner dross, consider the corner rounding first. In terms of parameters, you can reduce the focus and increase the air pressure. For the overall hard slag, you need to reduce the focus, increase the air pressure, Increase the cutting nozzle, but the focus is too low or the air pressure is too high, which will cause the section to be stratified and rough; if there is granular soft slag on the whole, the cutting speed can be increased or the cutting power can be appropriately increased; if there is slag on the side of the cutting end, then You can check whether the gas supply is insufficient and the gas flow cannot keep up.
2. The problem of cutting the carbon steel section: the section of the thin plate is not bright enough, and the section of the thick plate is rough. If you want a bright section, you must first have a good board, the surface is free of rust, paint, and oxide scale, and secondly, the oxygen purity is as high as 99.5% or more. When cutting, use a small cutting nozzle to double layer 1.0 or 1.2. The cutting speed needs to exceed 2m/min. The cutting air pressure should not be too high; if you want a thick plate to cut the quality of the section, you must first ensure the purity of the plate and gas, and then the selection of the cutting nozzle. The larger the aperture, the better the section quality, but at the same time, the section taper will be greater.
