Dot matrix engraving Dot matrix engraving is similar to high-definition dot matrix printing. The laser head swings left and right, engraving a line composed of a series of dots each time, and then the laser head moves up and down at the same time to engrave multiple lines, finally forming a full-page image or text. Scanned graphics, text and vectorized graphics can all be engraved using dot matrix engraving.
Vector cutting Unlike dot matrix engraving, vector cutting is performed on the outer contour line of the image. We usually use this mode to perform penetrating cutting on materials such as wood, acrylic particles, and paper, and can also perform marking operations on the surfaces of various materials.
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 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 adjust the speed using the engraving machine panel or the computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The advanced motion control system of the Hummer machine allows you to obtain ultra-fine engraving quality at high speed.
Engraving intensity: Engraving intensity refers to the intensity of the laser beam projected onto the surface of the material. For a specific engraving speed, the greater the intensity, the greater the depth of cutting or engraving. You can adjust the intensity using the engraving machine panel or the computer's print driver. The adjustment range is 1% from 1% to 100%. The greater the intensity, the greater the speed. The deeper the cutting depth is.
Spot size: The laser beam spot size can be adjusted using lenses of different focal lengths. Small spot lenses are used for high-resolution engraving. Large spot lenses are used for lower-resolution engraving, but they are the best choice for vector cutting. The standard configuration of new equipment is a 2.0-inch lens. Its spot size is in the middle and is suitable for various occasions.
Engravable materials: wood products, plexiglass, metal plates, glass, stone, crystal, Corian, paper, two-color plates, aluminum oxide, leather, resin, spray-coated metal.
