In the early application of laser cutting, focusing is mainly done by hand. Now, with the development of laser technology, this manual focusing method has been gradually eliminated, and the automatic focusing function has been gradually realized.
So why does the optical fiber laser cutting machine focus?
When the optical fiber focus of the laser cutting machine is in a good position, good cutting results can be obtained with small kerf and high efficiency. Different laser focus positions correspond to different roughness of the cutting surface. The adjustment of the focus position for optimizing the cutting quality of the optical fiber laser cutting machine is determined from the situation that the cutting focus is located in the cutting material.
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 piercing focus of the manually focused cutting head cannot be adjusted, and the piercing focus is consistent with the cutting focus. When the thick plate is perforated, the energy is insufficient and the piercing speed is slow. The cutting head with automatic focusing can automatically adjust the focus during perforation, adjust the focus size during perforation, improve the perforation energy, and increase the perforation speed during thick plate perforation.
With the auto focusing function, the machine can automatically and quickly adjust the focus to the appropriate position when processing workpieces of different materials and thicknesses. This can significantly improve the processing efficiency of the laser cutting machine, and the thick plate perforation time will be greatly reduced.
Therefore, for laser cutting machine, auto focusing function is an important and indispensable function.
