The main working principle of the fiber laser marking machine is to mark the fiber laser beam on the surface of various materials including metals and some non-metals in the form of various patterns, signs or other labels. These traces are permanent and will not disappear with the passage of time. Therefore, metals or non-metals can carry the cultural connotation of products, enterprises or special symbols to a wider range of people and places, not only marking patterns or words, but also culture and value. The composition of the fiber laser marking machine includes the lasers, the scanner, the lens, the cooling system , the control system, the power supply, as discussed below.
