Laser engraving machine is a kind of equipment that can mark the surface of various materials. Its principle is to use the high temperature generated by the laser beam to ablate the surface of the material to different degrees to achieve the purpose of leaving a mark.

Principle introduction：

The laser engraving machine can mark various complicated graphics, characters, barcodes, etc. on various materials. The marking speed is fast and permanent. It is the first choice for marking products and upgrading product grades.

The popular name of laser engraving machine is generally laser engraving machine, laser engraving machine, laser marking machine, laser engraving machine, etc. But its professional name is called laser marking machine. Then why do people call him a laser machine? In fact, the English for laser is laser. It is also called laser. The laser marking machine is used to mark various text patterns, etc. Some people like to call it engraving because of its permanent nature. So there is a laser engraving machine to say so.

Laser cutting plotter can be divided into semiconductor laser cutting plotter, YAG laser cutting plotter, CO2 laser cutting plotter, and fiber laser cutting plotter according to the different lasers. So what is the laser engraving machine composed of? Generally speaking, the laser engraving machine is divided into two parts:

1. Optical system

The optical system of the laser engraving machine is composed of a laser power supply, a laser generator (laser), a beam expander, a total reflection half mirror, a Q switch, a Q driver, a scanning galvanometer, and a focusing mirror.

2. Control system

The laser cutting plotter control system includes a computer, marking control card, marking software, etc.

The above-mentioned optics is for metal and laser engraving machine. Metal laser plotter includes YAG laser plotter, semiconductor laser plotter, and fiber laser plotter. The CO2 laser engraving machine is a non-metal laser engraving machine. They are different:

The CO2 laser cutting plotter has no Q switch or Q drive.

The two lasers are different. The CO2 laser is a tube filled with gas.

The laser wavelength is different.
