laser engraving machine

Structure and application of laser engraving machine:
Metal laser engraving machine

The utility model comprises a laser and a gas nozzle on its output optical path. One end of the gas nozzle is a window, and the other end is a nozzle coaxial with the laser and optical path. The side of the gas nozzle is connected with a gas pipe, especially the gas pipe is connected with an air or oxygen source. The pressure of the air or oxygen source is 0.1-0.3mpa. The inner wall of the nozzle is cylindrical, and its diameter is 1.2-3mm The length is 1-8mm; The oxygen in the oxygen source accounts for 60% of the total volume, and a reflector is arranged on the optical path between the laser and the gas nozzle, which can improve the carving efficiency, make the surface of the carved part smooth and round, quickly reduce the temperature of the carved non-metallic material, and reduce the deformation and internal stress of the carved object; It can be widely used in the field of fine carving of various non-metallic materials.

*Dot matrix engraving dot matrix engraving is similar to high-definition dot matrix printing. The laser head swings left and right to carve a line composed of a series of points each time. Then the laser head moves up and down at the same time to carve multiple lines, and finally forms a whole page of image or text. Dot matrix engraving can be used for scanned graphics, text and vectorized graphics.

*Vector cutting is different from dot matrix carving. Vector cutting is carried out on the outer contour line of graphics and text. We usually use this mode to cut through wood, yak grain, paper and other materials, and we can also mark on the surface of various materials.

*Engraving speed: engraving speed refers to the speed of laser head movement, usually expressed in IPS (inch / second), high speed brings high production efficiency. Speed is also used to control the depth of cutting. For a specific laser intensity, the slower the speed, the greater the depth of cutting or carving. You can use the engraving machine panel to adjust the speed, you can also use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment is 1%. Hummer's advanced motion control system enables you to achieve ultra-fine carving quality at high speed.

*Engraving intensity: engraving intensity refers to the intensity of the laser beam on the surface of the material. For a specific carving speed, the greater the intensity, the greater the depth of cutting or carving. You can use the engraving machine panel to adjust the intensity, you can also use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment is 1%. The greater the strength, the greater the speed. The deeper the cut is.

*Spot size: the spot size of laser beam can be adjusted by lenses with different focal lengths. The lens with small spot is used for high resolution engraving. Large spot lens is used for low resolution engraving, but it is the best choice for vector cutting. The standard configuration of the new device is a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions.

*Engravable materials: wood products, plexiglass, metal plate, glass, stone, crystal, Corian, paper, double color plate, alumina, leather, resin, spray metal.
