For carbon steel, an important factor in improving the cutting section is to control the heat input to the sheet and to ensure adequate combustion of the laser-irradiated portion. An important factor for improving the cutting section for stainless steels is the improvement of the beam (improvement in depth of focus) and the efficient use of ancillary gases. Bright surface cutting technology is to improve the results obtained with the vibration generator and nozzle. The laborer laser SuperCut fiber laser cutting machine has a brilliant surface cutting technology, and the finished product has a smoother cross section, higher precision and almost perfect verticality.
