Definition

Laser engraver, as the name implies, is a type of CNC equipment that uses the laser beam to engrave materials that need to be engraved. The laser engraving machine is different from the mechanical engraving machine and other traditional manual engraving methods. Mechanical engraving machine uses mechanical means, such as diamond and other materials with extremely high hardness to engrave other things. The laser engraving machine uses the thermal energy of the laser to engrave the material. The laser in the laser engraving machine is the core. Generally speaking, the laser engraving machine is more widely used, and the engraving accuracy is higher and the engraving speed is faster. Compared with the traditional hand-engraving method, laser engraving can also make the engraving effect very delicate, which is no less than the level of hand-engraving. It is precise because the laser engraving machine has so many advantages, so now the application of laser engraving machine has gradually replaced the traditional engraving equipment and methods. Become the main engraving equipment.

Working Principle

Laser engraving means that the light energy of the laser beam causes the chemical and physical changes of the surface material to engrave the traces, or the light energy burns out some of the materials to display the desired etching graphics and text; according to the engraving method, it can be divided into Dot matrix engraving and vector cutting.

"Heat processing" laser beams with a higher energy density (it is a concentrated energy flow) are irradiated on the surface of the material to be processed, the material surface absorbs the laser energy, and a thermal excitation process is generated in the irradiation area, so that the material surface (or coated Layer) The temperature rises, causing metamorphosis, melting, ablation, evaporation and other phenomena.

Applications

The laser can process almost any material, but due to the limitation of the power of the laser emitter, the materials that can be processed by the CO2 laser engraver are mainly non-metallic materials, and the fiber laser engraver is mainly based on metal materials. The engraving materials include plexiglass, plastic, two-color board, glass, bamboo, foam, cloth, leather, rubber board, stone, artificial stone PVC board, wood products, metal plate, crystal, Corian, paper, alumina, Resin, sprayed metal.

Benefits

1. Wide range: CO2 laser can engrave and cut almost any non-metallic material. And the price is low.

2. Safe and reliable: Non-contact processing is adopted, which will not cause mechanical extrusion or mechanical stress on the material. No "knife marks", not damage the surface of the processed parts, not deform the material.

3. Accurate and meticulous: the processing accuracy can reach 0.02mm.

4. Eco-friendly: The diameter of the light beam and light spot is small, generally less than 0.5mm, saving materials, safety, and hygiene.

5. Consistent effect: ensure that the processing effect of the same batch is completely consistent.

6. High speed: You can immediately engrave and cut according to the output of the pattern by the computer.

7. Low cost: Not limited by the number of processing, laser processing is cheaper for small batch processing services.
