A laser cutting machine is a computer-controlled device that uses a laser to cut through materials. The laser source generates a beam, which is then focused and directed at the workpiece using a lens or mirror.
The material to be cut is placed on a work table under the laser head. This head moves the laser beam according to a pre-programmed pattern, cutting through the material. The concentrated laser beam melts, vaporizes or burns the material, creating a precise and clean edge.

Principles of laser cutting
The laser cutting process is based on the use of a high-energy laser that is directed, usually by an optical system. Laser optics and a CNC (computer numerical control) system are used to control both the laser beam and the material.
There are three main techniques in the laser cutting method. The first, CO2 laser cutting, uses carbon dioxide gas as the active medium. This technology is typically the most expensive and is mainly used for cutting heavier metals such as stainless steel or aluminum. The second technique, known as fiber laser cutting, uses a fiber optic cable to transmit the laser beam. It is versatile and can be used in the processing of a variety of materials, although it can be expensive. The third method, semiconductor laser cutting, involves using a single crystal to generate a laser beam. This technique is often used when machining plastics and aluminum alloys.
The use of laser machines for cutting
Laser cutting machines are widely used in various industrial sectors, thanks to their outstanding performance and numerous advantages. In this article, we will discuss the application of these machines in the sheet metal working industry. The history of laser cutting machines dates back to the 60s of the twentieth century, when they were mainly used for welding purposes. However, technological advances have meant that these machines have begun to be used more widely in the sheet metal industry, including not only cutting, but also engraving and other processes. So, what are the specific applications of laser cutting machines in sheet metal processing?
Applications in the Iron Tower Industry
Laser cutting machines are not only used in the iron tower industry, but also in many other industrial sectors. In the iron tower industry, these machines are used to cut and weld steel plates, which saves time and money in this industry.
