The working principle of Laser engraving machine:
1. Lattice engraving as the same as a high-resolution lattice printing. When the laser engraving machine working, through swing the laser head to engraving a line composed of a series of points, and then engraving more line, the last constitute a full-page image or text. Scanning of graphics, text and graphic can use lattice vector quantization.
2. Vector cutting: vector cutting is the outer contour line in the graphic. We usually use this mode in the wood, paper,etc, it can also be used in a variety of material surface for marking operation.
3. Laser engraving speed: the speed of the movement refers to the laser engraving speed, usually with IPS (inches per second), high speed with high production efficiency.Speed is also used to control the depth of cut, for a specific laser intensity, the slower speed, cutting or engraving depth is greater.
4. Size: laser beam spot size can use different focal length of lens.The sculpture of light lens used in high resolution.Large spot lens used for low resolution carving, but for vector cutting, it is the best choice. New equipment standard lens is 2.0 inches. The spot size in the middle, is suitable for various occasions.
5. Laser engraving materials: wood, organic glass, metal, glass, stone, crystal, corian, paper, double color boards, alumina, leather, resin, plastic, metal.
The advantages of laser engraving machine:
1. The pattern of laser engraving, anti-counterfeiting function is strong, and graphic exquisite, fine lines, washing resistance, wear resistance.
2. Environmental protection and energy saving, no pollution, do not contain any toxic substances, convenient through the ROHS standard, convenient production.
3. Save material: laser processing with computer programming, can put the different shapes of products to suit cut, maximize the utilization rate of materials, greatly reduces the enterprise the cost of materials.
4. Precision: laser engraving the thin line in the material surface can reach 0.015 mm wide, laser cutting notch width is generally 0.1 ~ 0.5 mm, welding cold welding seam formation, no heat affected zone.
5. Material is not easily deformed: laser machine have fine laser beam, the high speed, energy concentration, quantity of heat is small, so to be processed material cause deformation of material also is very small.
6. Surface processing: laser engraving machine, welding surface without burr, good surface finish. Can greatly shorten the development period of new products.
