The laser engraving tool lies in the laser and the laser beam. The laser generates a laser beam and the optical mechanism emits such a laser beam and focuses on the surface of the material. The material is rapidly vaporized to form pits, under the influence of the high energy density laser beam.
The laser engraver uses a computer to control the X, Y, and Z axes to move the laser head, and to control the laser to switch as needed. The image information processed by the software is previously designed and stored on the computer.
When the laser engraver reads design information from the computer sequentially, the laser head moves back and forth from left to right and top to bottom along the design route. And finally, it forms a complete piece of graphics or text, realizing the automation of carving.
The laser processing technology belongs to non-contact processing. The mechanical engraver's tool carves through direct contact with the material. But it does not change the internal elements of the material. It relies on the high density of laser energy and has strong laser engraving performance.
Features include a wide range of processing materials and smooth cutting edges without secondary polishing. And it does not generate dust and achieves high processing speed and high precision, less waste and high efficiency.

Laser engraving is a popular option that provides a permanent and legible marking on an object through etching, ablation, or deep laser engraving. It is similar to laser marking, but the resulting appearance differs due to the depth of laser penetration.
Laser engraving is commonly used to create permanent serial markings on substrates made of: Metal, Wood, Plastic, Leather.
Benefits Of Laser Engraving Over Traditional Processes
Compared to manual engraving:
Minimally Invasive: Laser engraving can be performed at a range of depths without any direct contact at all. Surface marks can even be done on stainless steel with no depth. Overall, lasers are less damaging than manual engraving and keep the substrate material’s physical integrity intact.
Precise: Lasers provide a level of control that’s impossible to achieve manually. Compared to hand-engraving, the process is swift, clean, and highly repeatable, with little room for human error.
Versatile: A single laser engraving machine can be used to create a host of different designs with only minimal calibration. They can also produce exceptionally complex patterns.
Affordable: On average, laser devices last longer than other engraving machines and require less maintenance, resulting in savings that can be passed along to the consumer.
Fast: Lasers can be programmed to render virtually any design in a matter of moments. Because the process is automated, it’s easy to scale production runs as needed according to demand.
Long-Lasting: Laser-engraved designs are permanent but can wear over time, depending on the substrate material that’s used. Soft metals, for example, may experience more signs of wear than hardwood. In general, however, laser-engraved designs tend to have a longer lifespan compared to other engraving methods.
