Laser cutting machine brand | Analysis of laser cutting principle

As we all know, the cutting technology of Laser Cutting Machine is gradually replacing the traditional cutting process. So, what is the principle of laser cutting? After consulting professionals, now, follow me to see the working principle of this seemingly very powerful laser cutting machine!

The laser cutting machine is the laser emitted by the laser, after passing through the pre-set optical path system, is focused by many laser beams on the surface of the material to be processed, so that the laser cutting machine brand can form a high energy density with high power density. laser beam. When the laser beam with high power density is emitted to the surface of the object to be processed, due to the very high temperature, the surface of the object to be processed reaches its own melting point or its own boiling point, and the laser beam hits the surface of the workpiece to be processed. According to the trajectory that needs to be cut pre-set by the computer, there is a relative movement between the laser beam with high energy and the object to be processed, so that a slit is formed on the surface of the object to be processed. cutting purpose.

Laser sounds very mysterious, but in fact, laser is the same as the natural light we are familiar with in daily life. Laser is also a kind of light. Since it is light, people with certain physical foundation know that light is caused by particle transition. can even be converted. However, lasers are different from ordinary light in the general sense. The difference from ordinary light is that the laser is completely dependent on its own spontaneous emission in a very, very short time at the beginning of its generation, and is determined by the excitation radiation in the subsequent motion trajectory. It is precisely because of this that the color of the laser is very pure.

The principle of laser cutting is to use the laser beam to focus on the surface of the processed object to generate energy with a very high power density. One of the components of the laser cutting machine, the laser is under the control of the preset program of the computer, the laser discharges in the form of pulses, thereby emitting pulsed lasers. This pulsed laser has the characteristics of repeating high frequency, so it can naturally form a certain regular frequency.

This high-frequency and high-energy pulsed laser is transmitted through a preset optical path, and then reflected, and then focused on the surface of the object to be processed through the focusing lens group on the equipment. After focusing, it will form a Another light spot with very high energy, this light spot is irradiated near the place where the processed object needs to be cut, under the control of the pre-set computer program, due to the extremely high energy of the light spot, the temperature is also very high. , which can make the surface of the processed material instantly vaporized or melted by the extremely high temperature, thus achieving the purpose of cutting.

The laser cutting principle used by the laser cutting technology also determines that the laser cutting process greatly improves the cutting quality of the processed materials in the traditional cutting process. This also makes laser cutting technology applied in many fields. Laser cutting technology sounds very high-end and high-end. After the above introduction to the principle of laser cutting, do you have a further understanding of laser cutting technology? Many things just seem difficult, but after figuring it out, and Not as complicated as imagined.
