As a modern precision machining method, laser marking machine technology has unique advantages compared with corrosion and pneumatic machining. Using a laser as additive means, it has no machining force with the workpiece and has the advantages of no contact, no cutting force, and small thermal impact, so as to ensure the original accuracy of the workpiece. At the same time, the material has wide adaptability, can make very fine marks on the surface of a variety of materials, and has very good durability.
