The working principle of laser engraving machine


The gas nozzle which comprises a laser and its output light path, end gasnozzle for the window, the other end is the jet and laser, optical path coaxial,side gas nozzle connected with a pipe, especially the trachea with air or oxygensource is connected, the source of air or oxygen pressure of 0.1 ~ 0.3MPa,said nozzle the inner wall of the cylindrical), and its diameter is 1.2 ~ 3mm, 1 ~ 8mm in length; the source of oxygen in the oxygen accounted for 60% of the total volume, light path is provided laser and gas the nozzle between the mirror,it can improve the efficiency of the surface carving, carved the smooth, mellow,quickly reduce carved nonmetal material temperature, reduce the deformationand internal force of sculpture; and can be widely used for fine carving field forvarious non-metallic materials.

Laser engraving machine working principle:

* dot matrix engraving sculpture resembles a high-resolution dot matrix printer.Laser head from side to side, each carved out a composed of a series of points of a line, then the laser head to move up and down carved lines, the last full page image or text. Scan graphics, text and vector graphics can use bitmap carving.

* vector cutting and dot matrix engraving, vector cutting is carried out in the graphic outline of the line. We usually use this mode for the penetration of the cutting in wood, Senanayake tablets, paper and other materials, can also bemarking operation on the surface of various materials.

* engraving speed: engraving speed refers to the laser head moving speed,usually with IPS (inches per second), high speed and high production efficiency. Speed is also used to control the cutting depth, for a particular laser intensity, the slower the speed, cutting or engraving depth is large. You can use the engraving machine panel adjustment speed, also can use the computer to print driver to adjust. In the 1% to 100% range, the adjustment range is 1%. Hummermachine advanced motion control system so that you can be in high speed engraving, still get the ultra fine engraving quality.

* carving strength: carving strength refers to shoot to the material surface laser intensity. For the specific speed of engraving, intensity, cutting or engraving depth is large. You can use the engraving machine panel adjustment strength,also can use the computer to print driver to adjust. In the 1% to 100% range,the adjustment range is 1%. The intensity is big, the equivalent velocity. The cutting depth is deeper.

* spot size: the laser beam spot size can be adjusted by different focal length lens. Small spot lens used for high resolution carving. Large spot of the lens used for low resolution carving, but for vector cutting, it is the best choice. The standard configuration of the new device is 2 inches of lens. The spot size in the middle, is suitable for various occasions.

* carving materials: wood, organic glass, metal plate, glass, stone, crystal,Corian, paper, color plates, aluminum, leather, resin, metal spray.
