How Does Fiber Laser Cutting Work?

1. What is laser cutting?

The high-energy-density laser beam is used to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material starts to vaporize and form vapor. The jetting speed of these vapors is very high, and at the same time as the vapor jets, cuts are formed in the material. With the continuous development of the current storage tank industry, more and more industries and companies have applied laser cutting to storage tanks(3 photos), and more and more companies have entered the storage tank industry. However, due to reduced subsequent processing Therefore, it is feasible to use this equipment in large-scale production.

2. What is a fiber laser and how does it work?

Fiber laser is a new type of fiber laser that is newly developed in the world. It outputs high-energy-density laser beam, which is concentrated on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by the numerical control mechanical system Realize automatic cutting by irradiating position. Compared with bulky gas lasers and solid-state lasers, it has obvious advantages and has gradually developed into an important candidate in the fields of high-precision laser processing, lidar systems, space technology, and laser medicine.

3. How does fiber laser cutting work?

The fiber laser cutting machine can be used for plane cutting or bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting processing such as metal plates. At the same time, it can be used for three-dimensional cutting with a mechanical arm instead of the original imported five. Axis laser. Compared with the ordinary carbon dioxide laser cutting machine, it saves more space and gas consumption, and has a high photoelectric conversion rate. It is a new energy-saving and environmentally-friendly product and one of the world's leading technological products.

The principle of the fiber laser cutting machine: fiber laser is to dope the pump material into the fiber. After the laser of the specific wavelength emitted by the semiconductor laser is combined, the fiber will generate laser light and focus on the surface of the workpiece, so that the workpiece is The area irradiated by the spot is melted and vaporized instantaneously, and the spot irradiation position is moved by the computer-controlled numerical control mechanical system to realize automatic drilling. It is a high-tech equipment integrating laser technology, numerical control technology, and precision machinery technology.
