Why carbon dioxide CO2 laser marking machine is not suitable for engraving metal

Usually, laser marking machines use different marking machine types depending on the material, because the configuration principles of different models are very different, and they are very sensitive to the product material. Many merchants ask why the carbon dioxide laser marking machine can not mark metal products? The following laser editor will give you an analysis: carbon dioxide laser marking machine is also called CO2 laser marking machine. Generally used in wood products, plexiglass, glass, stone, crystal, Corian, paper, two-color board, alumina, leather, resin, etc.

1. Dot matrix engraving Dot matrix engraving is like high-definition dot matrix printing. The laser head swings left and right, engraving a line consisting of a series of points each time, and then the laser head moves up and down at the same time to engrave multiple lines, and then forms a full-page image or text. Scanned graphics, text and vectorized graphics can be engraved using dot matrix.

2. Vector cutting is different from lattice engraving. Vector cutting is carried out on the outer contour of the graphic. We usually use this mode for penetrating cutting on wood, acrylic, paper and other materials, and can also be used for marking on a variety of material surfaces.

3. Engraving speed: Engraving speed refers to the speed at which the laser head moves, usually expressed in IPS (inches per second). High speed brings high production efficiency. Speed u200bu200bis also used to control the depth of cut, for a particular laser intensity, the slower the speed, the greater the depth of cut or engraving. 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%. The advanced motion control system of the Hummer machine can enable you to obtain ultra-fine engraving quality during high-speed engraving.

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

5. Spot size: The spot size of the laser beam can be adjusted by using lenses with different focal lengths. Small spot lens for high resolution engraving. A lens with a large spot is used for lower resolution engraving, but for vector cutting it is the best choice. Standard on the new device is a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions.

Carbon dioxide laser marking machines generally use CO2 lasers, and the power of the laser tubes currently used belong to the range of medium and small power. Z largest is also 300W. Originally, metals absorb less laser light at this medium wavelength. Therefore, carbon dioxide laser marking machines are generally not used to engrave metal.
