Do you know anything about laser cutting machines? With the development of laser cutting technology, laser cutting has been applied in more and more fields, and more and more suitable materials have been used. But how much do you know about the problems that laser cutting machines often encounter? Let’s take a look.
1、 What is the working principle of a laser cutting machine
Laser cutting is a thermal cutting method that uses a focused high power density laser beam to irradiate a workpiece, rapidly melting, vaporizing, ablating, or reaching the ignition point of the material at the irradiated area. At the same time, the molten material is blown out by a high-speed airflow coaxial with the beam, and the laser spot irradiation position is moved by a numerical control mechanical system to achieve cutting of the workpiece.
2、 Is the operation of the laser cutting machine dangerous
Laser cutting is a very environmentally friendly cutting method, generally speaking, there is no harm to the body. Compared to ion cutting and oxygen cutting, laser cutting produces less dust, weak illumination, and low noise. However, if you do not follow the correct operating methods, it is easy to injure others by mistake.
3、 Factors affecting the accuracy of laser cutting machines
There are many factors that affect the accuracy of laser cutting, some of which are determined by the equipment itself, such as the accuracy of the mechanical system, the degree of vibration of the workbench, the quality of the laser beam, the impact of auxiliary gases and nozzles, etc; Some are inherent factors of the material, such as the physical and chemical properties of the material, the reflectivity of the material, and so on; Other factors are based on specific processing objects and user quality requirements, and corresponding adjustments are made to determine relevant parameters, such as output power, focus position, cutting speed, and auxiliary gas.
4、 What types of lasers are there and what are the differences
Currently, lasers used in laser processing and manufacturing mainly include CO2 lasers, YAG lasers, and fiber lasers. High power CO2 lasers and YAG lasers are widely used in confidential processing; Fiber lasers based on fiber bit matrices have significant advantages in reducing threshold values, oscillating wavelength ranges, and wavelength tunable performance, and have become emerging technologies in the current laser field.
5、 What is the cutting thickness of the laser cutting machine
Currently, the thickness cut by laser cutting machines generally does not exceed 50mm. Compared to other cutting methods, laser cutting machines have significant advantages in cutting materials that require accurate dimensions below 20mm.
6、 Application range of laser cutting machine
With its cutting range, laser cutting machines are widely used in industries such as automobile manufacturing, kitchenware industry, sheet metal processing, advertising industry, machinery manufacturing, chassis and cabinets, elevator manufacturing, fitness equipment, etc.
However, generally, laser cutting machines are mainly divided into metal cutting and non-metal cutting. Different laser cutting machine manufacturers produce different types of laser cutting machines, and their focus is also different
