The difference between the fiber laser marking machine and the co2 marking machine


Fiber laser marking machine: Fiber laser has become a hot spot in laser physics research in recent years. It is unanimously considered to be a new generation of products that can completely replace solid-state lasers. A fiber laser refers to a laser using a rare earth-doped glass fiber as a gain medium. The fiber laser can be developed on the basis of a fiber amplifier: under the action of pump light, a high power density is easily formed in the fiber, resulting in a laser of the laser working substance. The energy level "particle number inversion" can form a laser oscillation output when a positive feedback loop (constituting a resonant cavity) is appropriately added. Fiber laser marking machines use laser beams to mark permanent surfaces on a variety of different materials. The effect of marking is to expose deep substances by evaporation of surface substances, or to "engraving" traces by physical changes of surface materials caused by light energy, or to burn out some substances by light energy to show the desired etching pattern. , text, barcode and other graphics.

Features

1. It can process a variety of metal and non-metal materials. In particular, marking high hardness, high melting point and brittle materials is more advantageous.

2, belonging to non-contact processing, no damage to the product, no tool wear, good marking quality.

3. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.

4, high processing efficiency, computer control, easy to achieve automation.

Application field

Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communication products, aerospace equipment, various automotive parts, home appliances, hardware tools, molds, wire and cable, food packaging, jewelry, tobacco and military matters, etc. Marking of domain graphics and text, as well as high-volume production line operations.

Carbon dioxide laser marking machine: CO2 laser marking machine adopts imported package CO2 laser, equipped with German high-speed scanning galvanometer and beam expanding focusing system, with high marking precision and high speed; ZJ-2626A laser height can be adjusted up and down, easy to use, It can replace all kinds of lenses with marking format; long working time, clear and beautiful marking, powerful software, water mark, flight marking; fixed laser marking design, simple operation, perfect up and down ventilation system, work environment protection Safe; suitable for all kinds of leather, leather, two-color board, plastic and all kinds of solid materials.

working principle

The CO2 laser marking machine adopts an infrared light band and a 10.64μm gas laser to charge the CO2 gas into the high-voltage discharge tube to generate a glow discharge, so that the gas molecules release the laser, and the laser energy is amplified to form a laser beam for processing the material. The laser beam vaporizes the surface of the object to achieve the purpose of engraving. The above is the difference between the two, but the bigger point is the lasers of both, one using a fiber laser and the other using a gas laser.
