Fiber lasers are everywhere in the modern world. Due to the different wavelengths they can generate, they are widely used in industrial environments to perform cutting, marking, welding, cleaning, texturing, drilling and a lot more. They are also used in other fields such as telecommunication and medicine.
What is a fiber laser cutter? And how are works for fiber laser cutting machines? Let’s dive into it.
A fiber laser cutting machine is a laser cutting machine with a fiber laser generator as the light source. Fiber laser is a new type of fiber laser developed internationally. It outputs a high-energy-density laser beam and concentrates on the surface of the workpiece so that the area irradiated by the ultra-fine focal spot on the workpiece is instantly melted and vaporized.
Let’s take carbon steel as an example. As shown in Figure 1, a 1000 watt fiber laser cutting machine is used. For carbon steel materials below 10mm, when the thickness of the carbon steel is less than 2mm, the cutting speed can reach up to 8 meters per minute. When it is 6mm, the cutting speed is about 1.6 meters per minute, and when the thickness of carbon steel is 10mm, the cutting speed is about 0.6 meters to 0.7 meters per minute.
Fiber lasers are known as the "third-generation lasers" and have many advantages such as good output laser beam quality, high energy density, high electro-optical efficiency, convenient use, wide range of processable materials, and low overall operating costs. It is widely used in engraving, marking, cutting, drilling, cladding, welding, surface treatment, rapid prototyping and other material processing fields.
The laser cutting machine is high-tech intelligent equipment integrating numerical control technology, laser cutting technology and inverter power supply technology. The development of laser cutting technology is based on the common progress of computer control, laser optics, power electronics and other disciplines. Among them, the numerical control system plays a very important role.
The laser head is an important part of the fiber metal cutting machine, used to generate the laser beam energy for cutting, similar to the human heart. Today, we mainly introduce the structure and types of fiber laser cutting heads.
The laser cutting machine for mass production and processing can cut the maximum thickness of different material boards as shown in the figure (thickness unit mm):
Laser technology, together with computer technology, semiconductor technology, and atomic energy technology, is one of the world's four great inventions in the 20th century and has had a huge impact on the development of the entire society. The laser is widely used in all walks of life because of its good directivity, monochromaticity, and high energy concentration. From daily necessities, food, housing, and transportation, to all aspects of processing and manufacturing in the industrial field, to medical beauty, lasers are everywhere, affecting all aspects of public life. From the perspective of the development of a country's laser industry, the overall industrial manufacturing level can be seen to a certain extent.
Globally, the United States, Germany, and Japan are leading countries in the laser industry and technology. Due to the limited space of the article, this article will select ten representative laser companies in the world, and the following rankings are in no particular order. Through the general introduction of these companies, you can see the general outline of the development of the laser cutting machine.
Before using this fiber laser cutting machine, please master the relevant operation methods of the machine and understand the operation of each part of the machine. Correct operation is an effective measure to ensure the normal operation and personal safety of the sheet metal laser cutter. When using a laser cutting machine, please follow the following precautions and inspections before use.
When using a sheet metal laser cutting machine to process objects, it is necessary to learn the equipment use and maintenance skills of the fiber laser cutting machine to better exert the efficiency of the equipment and maximize the efficiency of the equipment.
The installation of the laser metal cutting machine is very important for every factory, so please read the following detailed information before the operation.
In daily cutting, although the traditional cutting machine can do very well, the smoothness of the material cutting is far from enough, and the roughness of the cut is more obvious. The reason why the laser metal cutting machine is widely used is that the CNC fiber laser cutting machine has common outstanding advantages and leading processing technology. When cutting materials, it not only has high power but also a good cutting effect, which is an incomparable advantage of traditional cutting machines. The laser metal cutting machine uses high-density laser beam operations to cut materials at high temperatures. The processing characteristics of the fiber laser cutting machine are fast speed, narrow cutting, smooth cutting surface, and small heat affected area. During processing, the CNC fiber laser cutting machine not only improves the production efficiency and the quality of the cut parts but also saves the processing cost to a certain extent and overcomes the waste of materials in the original cutting processing method.
Fiber laser is a new type of laser that is newly developed in the world. By outputting a laser beam with high energy density and focusing on the surface of the workpiece, the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by a CNC 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.
