With the continuous improvement of production demand, laser technology is also gradually mature. The advent of new laser head has changed the traditional manual focusing mode, and automatic focusing has successfully replaced the traditional focusing mode. The new automatic focusing cutting head has been widely used.
The perforation focus of the cutting head with manual focusing cannot be adjusted, and the perforation focus is consistent with the cutting focus. When the thick plate is perforated, the energy is insufficient and the perforation speed is slow. The focus of the auto focusing cutting head can be automatically adjusted during perforation, the size of the focus can be adjusted during perforation to improve the perforation energy, and the perforation speed can be increased during thick plate perforation.
In terms of perforation time, the speed of automatic focusing is half that of manual focusing, and the cutting effect is basically the same. However, automatic focusing will reduce the sheet over melting phenomenon caused by the short overheating time of the material. The advantage of automatic focusing is obvious, which can significantly improve the production efficiency and greatly reduce the perforation time of cutting thick plate materials. When processing workpieces of different materials and thicknesses, the machine can also quickly adjust the focus to the appropriate position.
Therefore, the auto focusing fiber laser cutting machine is prior to manual focusing in most aspects. With the progress of science and technology, the auto focusing laser cutting machine will be more practical, the processing effect will be more perfect, and provide better help for laser cutting.
