Laser engraving machine structure and working principle
- Sep 05, 2017 -

The laser engraving machine comprises a laser and a gas nozzle on the output optical path, one end of the gas nozzle is a window and the other end is a nozzle which is coaxial with the optical path of the laser. The side of the gas nozzle is connected with an air pipe, in particular the air pipe and air Or an oxygen source having a pressure of 0.1 to 0.3 MPa and an inner wall of said nozzle having a cylindrical shape having a diameter of 1.2 to 3 mm and a length of 1 to 8 mm,

Oxygen in said oxygen source is 60% of its total volume, and a mirror is arranged on the optical path between said laser and said gas jet. It can improve the efficiency of the carving, so that the surface of the carved smooth, rounded, quickly reduced the temperature of the carved non-metallic materials to reduce the deformation of the carved and internal stress; can be widely used for a variety of non-metallic materials The area of fine engraving.
