With the continuous development of laser technology, the laser cutting machine has played an unparalleled advantage in cutting metal plates. It not only has high cutting accuracy, but also has a smooth section without burrs. It can achieve good results whether it is cutting thick or thin plates. However, these cutting effects are closely related to the focus control of the laser cutting machine, just like the focus adjustment of a SLR camera. It is a principle that the focus can achieve a better imaging effect. In the initial application of laser cutting, focusing mainly relied on manual. However, with the continuous development of laser technology, manual focusing will eventually be eliminated and replaced by the automatic focusing function.
