In the early application of fiber laser cutting machines, their functionality was limited, and focusing could only be done manually without automatic focusing function. Manual focusing requires a certain level of technical proficiency from operators, and any slight carelessness during operation can have an impact on the accuracy and production efficiency of the product.
With the continuous improvement of production demand, laser technology has gradually matured, and the emergence of new laser heads has changed the traditional manual focusing mode. Automatic focusing has successfully replaced the traditional focusing mode, and the new automatic focusing cutting head has been widely used.
The perforation focus of the manually focused cutting head cannot be adjusted, and the perforation focus is consistent with the cutting focus. When piercing thick plates, the energy is insufficient and the perforation speed is slow. The autofocus cutting head can automatically adjust the focus during perforation, adjust the focus size to increase perforation energy, and increase perforation speed during thick plate perforation.
From the perspective 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 can reduce the phenomenon of sheet metal over melting caused by short material overheating time. The advantages of automatic focusing are obvious, which can significantly improve production efficiency and greatly reduce the perforation time for 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 automatic focusing fiber laser cutting machine is ahead of manual focusing in most aspects. With the advancement of technology, the automatic focusing laser cutting machine will be more practical, the processing effect will be more perfect, and provide better assistance for laser cutting.
