Working principle of laser engraving machine

On the optical path between the laser and the gas nozzle, there is a reflector, which can increase engraving performance, make the engraved place's surface smooth and round, quickly reduce the temperature of the non-metallic material to be engraved, and reduce deformation and interior of the engraved piece. tenseness;

Dot matrix engraving: Dot matrix engraving resembles high-definition dot matrix printing. The laser head swings left and right to engrave a line consisting of a series of dots each time, and then the laser head moves up and down to engrave multiple lines at the same time, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be engraved by dot matrix.

Vector cutting is different from dot matrix engraving, vector cutting is performed on the outer contour of the graphic. We usually use this mode for penetrating cutting on wood, acrylic, paper and other materials, as well as marking on the surface of a variety of materials.

Engraving speed: Engraving speed refers to the moving speed of the laser head, 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 use the panel of the engraving machine to adjust the speed, or 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 the Hamm machine allows you to still get ultra-fine engraving quality when engraving at high speed.

Engraving intensity: Engraving intensity refers to the intensity of the laser that hits 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 panel of the engraving machine to adjust the intensity, 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 depth of the cut is also deeper.

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