Laser cutting machine technology uses the energy released when the laser beam irradiates the surface of the metal sheet. The sheet metal is melted and the slag is blown away by the gas. Because the laser power is very concentrated, only a small amount of heat is transferred to the other parts of the metal sheet, causing little or no deformation. The use of laser can cut blanks of complex shapes very accurately, and the cut blanks do not need to be further processed.
The laser source generally uses a carbon dioxide laser beam with a working power of 500 to 5000 watts. The power level is lower than the power required by many household electric heaters, because the laser beam is concentrated in a small area due to the lens and mirror. The high concentration of energy enables rapid local heating to melt the metal sheet.
Using laser cutting equipment can cut stainless steel below 16mm, and adding oxygen to the laser beam can cut 8-10mm thick stainless steel, but after oxygen cutting, a thin oxide film will be formed on the cutting surface. The maximum thickness of the cut can be increased to 16mm, but the size error of the cut part is relatively large.
As a high-tech laser technology, since its inception, it has been developing laser products suitable for various industries according to different social needs, such as laser printers, laser beauty machines, laser marking CNC laser cutting machines, laser cutting machines and other products. Due to the late start of the domestic laser industry, it lags behind some developed countries in technology research and development to a large extent. At present, the laser products produced by domestic laser product manufacturers include some key parts such as laser tubes, drive motors, galvanometers, and focus. The mirrors are still imported. This has caused a rise in costs and increased the burden on consumers.
In recent years, with the advancement of domestic laser technology, the R&D and production of complete machines and some spare parts has gradually moved closer to advanced foreign products. In some respects even better than foreign products, coupled with the advantages of Jiege, still occupy a dominant position in the domestic market. However, in some precision processing and equipment, stability and durability, advanced foreign products still occupy an absolute advantage.
