The precision of laser marking machine is high. The light speed of laser is very fine. When it acts on the material surface, the small relocation accuracy can reach 0.01mm. It is suitable for marking fine instruments and parts. The current accuracy can meet the needs of marking on very small plastic and metal surfaces. Laser marking machine is a physical non-contact processing. There is no pollution source of any chemicals, and it is not limited to the shape of the processed products, round and square. It can be curved; It is suitable for a wide range of materials. It can mark the surface of almost all metal and non-metal materials (such as aluminum, stainless steel, glass, leather, cloth, paper, etc., different materials, different thicknesses and different hardness materials); Good compatibility, with other processing equipment to form a fully automated production line; The marking of laser marking machine is clear and beautiful, durable and wear-resistant, not easy to be altered and covered, which plays an anti-counterfeiting role to a certain extent; The laser marking machine has a long service life, the core of the whole equipment is the laser, and the service life is more than 20000 hours.
