We are a professional laser cutting machine manufacturer with over 10 years of industry experience. Today, we would like to introduce to you:
The principle of China manufacturer fiber laser cutting machine is mainly based on the high energy density and accurate control of laser. By irradiating the material surface with a laser beam, the material is melted, vaporized, and cut. The following is a detailed explanation of the principle of laser cutting machine.
1、 Laser generation and transmission
China manufacturer fiber laser cutting machines generate a high-energy laser beam through specific lasers such as CO2 lasers, fiber lasers, or YAG lasers. These lasers utilize the principle of electromagnetic radiation to generate high-energy beams with high brightness and directionality. The high-energy beam generated by the laser cutting machine is focused through a series of mirrors and lenses, making its energy highly concentrated on a very small point. The diameter of this focal point can usually reach the micrometer level, ensuring a high power density of the laser.
2、 Heating and melting of materials
When the high-energy beam of the laser cutting machine is irradiated onto the surface of the material, the material absorbs the laser energy, causing a rapid increase in temperature in the irradiated area. As the temperature increases, the material will melt, burn, or vaporize. For metal materials, auxiliary gases such as oxygen, nitrogen, or air are usually used to help blow away melted materials or promote chemical reactions (such as oxidation) to accelerate the cutting process.
3、 Cutting process
Under the control of a computer numerical control system, the high-energy beam of the laser cutting machine moves along a set path. This path is pre programmed based on the shape and size of the material to be cut. As the high-energy beam moves, the material is gradually cut open. Due to the high energy density and precise control of high-energy beams, the cutting process is very fast and accurate.
4、 Cooling and Forming
After cutting, the cutting edge is usually very smooth, and due to the small heat affected area, the degree of material deformation is low. At this point, appropriate cooling treatment can be applied to the cutting parts. After cooling, the cut parts can be used directly or subjected to subsequent processing.
5、 Characteristics and Applications
Laser cutting machines have advantages such as high precision, high speed, good cutting quality, non-contact processing, small heat affected zone, small material deformation, and smooth cutting. And it is widely used in fields such as metal processing, automobile manufacturing, aerospace, electronic appliances, etc., for cutting workpieces of various shapes and sizes.
In summary, the principle of a China manufacturer fiber laser cutting machine is to use a high-power density laser beam to irradiate the surface of a material, causing the material to melt, vaporize, and cut open. Through accurate computer numerical control systems and advanced auxiliary technologies, laser cutting machines can achieve high-precision and high-speed cutting operations, and are widely used in fields such as metal processing, automotive manufacturing, aerospace, etc.
