Working principle of laser engraving machine Dot matrix engraving Dot matrix engraving resembles high-resolution dot matrix printing. The laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head moves up and down at the same time to engraving multiple lines, and finally forms the entire image or text. Scanned graphics, text and vectorized graphics can be engraved with dot matrix. Vector cutting is different from dot matrix engraving. Vector cutting is performed on the outer contour of graphics.
We usually use this mode for penetrating cutting on wood, acrylic, paper, and other materials. It can also perform marking operations on the surface of various materials. Engraving speed: The engraving speed refers to the speed of the laser head. Generally, IPS ( Inches / second) means that high speed brings high productivity. Speed is also used to control the depth of the cut. For a specific laser intensity, the slower the speed, the greater the depth of the cut 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 is 1%.
The advanced motion control system of the laser engraving machine can make you still get super fine engraving quality when engraving at high speed: The engraving intensity refers to the intensity of the laser light on the surface of the material. For a specific engraving speed, the greater the intensity, the greater the depth of the cut or engraving. You can use the engraving machine panel to adjust the intensity, or you can use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment is 1%. The greater the intensity, the greater the speed.
The deeper the cut, the deeper the spot size: the spot size of the laser beam can be adjusted with lenses of different focal lengths. Small spot lenses are used for high-resolution engraving. Large spot lenses are used for lower resolution engraving, but for vector cutting it is the best choice. The new equipment comes standard with a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions. Engravable materials: wood products, plexiglass, sheet metal, glass, stone, crystal, Corian, paper, two-color board, alumina, leather, resin, plastic sprayed metal.
The laser engraving machine is mainly used for large-scale plastic word cutting, double-color plate engraving, plexiglass engraving and cutting. Leather garment processing industry: genuine leather, synthetic leather, artificial leather, cloth, fur with complex text graphics carving, cutting, carved hollows and so on. Craft processing, garment making, underwear, home furnishings, gloves, handbags, shoes, hats, toys and car flower industry cutting, carving, transcending fashion, showing individuality.
