Reveal why CO2 laser engraving machine can not engrave metal

Many friends are no stranger to laser engraving machine, usually laser engraving machine are applied to wood products, plexiglass, glass, stone, crystal, acrylic, paper, leather, resin and other materials. Some friends often have questions, why the laser engraving machine can not carve metal class material, in fact, this is related to the construction of the machine itself, the following follow GOLD MARK to understand.

Laser engraving machine generally use CO2 laser, so we often call the laser engraving machine CO2 laser engraving machine. And now the power of the laser tube belongs to the small and medium power range. The maximum is 300 W. Originally the metal of this wavelength laser absorption is less. So the laser engraving machine is generally not used to carve metal.

1.dot matrix engraving dot matrix engraving cool high-definition dot matrix printing. Laser head left and right swing, each time carving a line composed of a series of dots, and then the laser head moves up and down at the same time to carve multiple lines, and finally constitute a full version of the image or text. Scanned graphics, text and vectorized graphics can all be engraved using dot matrix.

2.vector cutting is different from dot matrix engraving, vector cutting is done on the outer contour line of the graphic. We usually use this mode for penetration cutting on materials such as wood, sub-grain, paper, etc., and also for marking operations on the surface of a variety of materials.

3.engraving speed: engraving speed refers to the speed of the laser head movement, usually expressed in IPS (inches / second), high speed brings high productivity. Speed is also used to control the depth of cut, for a specific laser intensity, the slower the speed, the greater the depth of cut or engraving. You can adjust the speed using the engraver’s panel, or you can use the computer’s print driver to do so. The adjustment is 1% in the range of 1% to 100%. Hummer machine advanced motion control system can enable you to carve at high speed, but still get super fine carving quality

4.Engraving intensity: Engraving intensity refers to the intensity of the laser shot to the surface of the material. For a specific engraving speed, the greater the intensity, the greater the depth of cutting or engraving. You can use the engraving machine panel to adjust the intensity, but also can use the computer’s print driver to adjust. The adjustment is 1% in the range of 1% to 100%. The greater the intensity, the greater the equivalent speed. The deeper the cutting depth is also

5. spot size: the laser beam spot size can be adjusted using different focal lengths of the lens. Small spot lens is used for high-resolution engraving. The lens with large spot is used for lower resolution engraving, but for vector cutting, it is the best choice. The new machine comes standard with a 2.0″ lens. Its spot size is in the middle and is suitable for a variety of applications.
