1, dot matrix engraving dot matrix engraving resembles high-definition dot matrix printing. The laser head swings left and right, carving a line consisting of a series of points at a time, and then the laser head moves up and down to carve multiple lines at the same time, finally forming a whole page of images or characters. Scanning graphics, characters, vectorized graphics and texts can all be carved with dot matrix.
2. Vector cutting is different from lattice carving. Vector cutting of the outer contour lines of graphics and characters. We usually use this mode to cut wood, yakuza, paper and other materials, and we can also mark the surfaces of various materials.
3. Engraving speed: Engraving speed refers to the moving speed of the laser head, which is usually expressed by IPS (inch/second). High speed brings high production efficiency. Speed is also used to control the cutting depth. For a given laser intensity, the slower the speed, the greater the depth of cutting or engraving. You can use the engraving machine panel to adjust the speed, or you can use the computer's print driver to adjust it. Within the range of 1% to 100%, the adjustment range is 1%. Hummer's advanced motion control system allows you to obtain ultra-fine carving quality at high speed.
4. Engraving intensity: Engraving intensity refers to the intensity of laser incident on 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 engraving machine panel to adjust the strength, or you can use the computer's print drive to adjust it. Within the range of 1% to 100%, the adjustment range is 1%. The greater the strength, the greater the equivalent velocity. The deeper the wound.
5. Spot size: The spot size of the laser beam can be adjusted by lenses with different focal lengths. Small spot lens is used for high resolution engraving. The lens with large spot is used for engraving with low resolution, but it is the best choice for vector cutting. The standard configuration of the new equipment is a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions.
Co2 laser is generally used in CO2 laser marking machine, but the power of the laser tube used now belongs to the medium and small power range. The maximum value is 300W w, and the original metal absorbs this medium wavelength laser less. Therefore, co2 laser marking machine is generally not used for engraving metal.
Scope of application of three common marking machines:
CO2 laser marking machine: It can be widely used in electronic components, electrical components, medicine, food, handicrafts, leather products, plastic products and other industries.
Semiconductor laser marking machine: especially suitable for some occasions that require fine marking and high precision. It is used in electronic components, hardware products, tool accessories, integrated circuits (ic), electrical appliances, mobile phone communication, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes, PPR pipes, medical devices and other industries.
Fiber laser marking machine: It is widely used in graphic and text marking of integrated circuit chips, computer accessories, industrial bearings, watches and clocks, electronic and communication products, aerospace devices, various auto parts, household appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military, and mass production line operations.
Therefore, it is very important to choose a suitable laser marking machine, and everyone can make a reasonable choice according to their own industry needs.
