Laser engraving machine is generally used in wood products, plexiglass, glass, stone, crystal, Corian, paper, two-color board, alumina, leather, resin, etc. However, there are problems in engraving metal materials by laser engraving machine. The reasons are as follows:

1. 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, and then the laser head moves up and down at the same time to carve multiple lines, and finally form a full page image or text. The scanned graphics, text and vectorized graphics and texts can be engraved with dot matrix.

2. Vector cutting is different from dot matrix carving. Vector cutting is carried out on the outer contour of graphics and text. We usually use this mode to carry out penetration cutting on wood, Yake grain, paper and other materials, and can also carry out marking on the surface of a variety of materials.

3. Engraving speed: engraving speed refers to the moving speed of the laser head, 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 engraving. You can use the engraving machine panel to adjust the speed, or you can use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment range is 1%. The advanced motion control system of Hummer machine can make you still get ultra-fine engraving quality when engraving at high speed.

4. Engraving intensity: engraving intensity refers to the intensity of the laser emitted on 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 strength, or you can use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment range is 1%. The greater the intensity, the greater the speed. The deeper the cutting is.

5. Spot size: the spot size of the laser beam can be adjusted by using lenses with different focal lengths. A small lens used for engraving. The lens with large light spot is used for engraving with lower resolution, 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.

Laser engraving machines generally use CO2 lasers, and the power of the laser tubes used now belongs to the medium and small power range. The maximum is 300W. Originally, metals absorb less of this medium wavelength laser. Therefore, laser engraving machines are generally not used to carve metal.
