As customers demand higher and higher accuracy of engraving, the application of laser engraving technology is becoming more and more widespread, laser engraving machine is mainly used in wood products, inorganic glass, acrylic, leather and other non-metallic materials, of which many people do not understand is why laser engraving machine can not engrave metal? The following follow GOLD MARK to understand the reasons for this.

Laser engraving machine mainly uses CO2 laser, and now with the power of the CO2 laser tube belong to the small and medium power range. Originally the metal absorption of the medium wavelength laser is less, resulting in 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 carved out of a series of dots composed of a line, and then the laser head while moving up and down carved out of multiple lines, and finally constitute a full version of the image or text. Scanned graphics, text and vectorised graphics can all be engraved using dot matrix.

2、vector cutting is different from dot matrix engraving in that vector cutting is done on the outer contour lines of the graphic. We usually use this mode for penetration cutting on materials such as wood, sub-grain, paper, etc. Marking operations can also be carried out on a wide range of material surfaces.

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

4、Engraving intensity: Engraving intensity refers to the intensity of the laser light directed at the surface of the material. For a given engraving speed, the higher the intensity, the greater the depth of cut or engraving. You can adjust the intensity using the engraver’s panel, or by using the computer’s print driver. The adjustment is 1% over a range of 1% to 100%. More intensity equates to more speed. The deeper the cut is also

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