The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator, and the focused laser acts on the printing material to instantly melt or even vaporize the surface material. By controlling the path of the laser on the surface of the material, it forms The required graphic marks.
Laser marking is characterized by non-contact processing and can be marked on any special-shaped surface. The workpiece will not deform and generate internal stress. It is suitable for marking metal, plastic, glass, ceramic, wood, leather and other materials.
The laser can mark almost all parts (such as pistons, piston rings, valves, valve seats, hardware tools, sanitary ware, electronic components, etc.), and the marks are wear-resistant, the production process is easy to be automated, and the marked parts have little deformation.
The laser marking machine uses the scanning method to mark, that is, the laser beam is incident on two mirrors, and the computer-controlled scanning motor drives the mirrors to rotate along the X and Y axes respectively. The laser beam is focused and falls on the marked workpiece to form Laser marking
