Laser marking machine include Fiber laser marking machine,CO2 laser marking machine UV laser marking machine and so on. Fiber is mostly popular and more widely used.

Basic principle of a laser target is, by a laser generator to generate the high-energy laser beam in a row, after focusing the laser effect material, the surface material moment fused, gasification, even through control the path of laser in material surface, forming a need by tags.
A laser target characteristics is contact processing, can be in any of the deformed surface engraving, artifacts will have internal stress, deformation and is suitable for metal, plastic, glass, ceramic, wood, leather and other materials.
Laser can be almost for all parts (such as piston, piston ring, valve, valve seat, hardware tools, sanitary ware, electronic components, etc.) for marking, and wear resistance, easy to realize automation production technology, small deformation is marked parts.
Laser marking machine marking by scanning method, the incident laser beam on the two mirrors, mirror driven by using computer controlled scanning motor respectively along the X, Y axis rotation, after focusing the laser beam to be markers of work pieces, thus forming the trace of the laser marker.
