XT Laser Metal Laser Cutting Machine
What is a metal laser cutting machine.
Metal laser cutting machine is an optoelectromechanical integrated equipment that uses lasers to cut metal materials. It has been widely used in metal sheet manufacturing and processing industries such as aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, etc.
At present, most laser cutting machines can be divided into CO2 laser cutting machines, fiber laser cutting machines, and YAG laser cutting machines. Among them, fiber laser cutting machines have only emerged in recent years, and due to their relatively low technical requirements, they have gradually become the mainstream of metal laser cutting machines. Our workshop uses fiber laser cutting machines.
The principle of metal laser cutting.
Metal laser cutting uses a laser tube to emit light, and then uses a reflector and focusing mirror to reflect and focus the light onto the laser head. The focused strong light illuminates the material that needs to be cut or carved, causing it to quickly melt due to high temperature, achieving the purpose of cutting or carving. During the cutting process, auxiliary gases suitable for the material being cut are also added. When cutting steel, oxygen must be used as an auxiliary gas to undergo an exothermic chemical reaction with the molten metal, which oxidizes the material and helps blow away the slag inclusions in the cutting seam. The auxiliary gas entering the nozzle can also cool the focusing lens, preventing smoke and dust from entering the lens holder and contaminating the lens, causing it to overheat.
The advantages and characteristics of metal laser cutting.
Compared with other thermal cutting methods, the general characteristics of laser cutting are fast cutting speed and high quality. Specifically summarized in the following aspects.
(1) Good cutting quality.
Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve good cutting quality.
The laser cutting slit is thin and narrow, with both sides of the slit parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05 mm.
2. The cutting surface is smooth and beautiful, with a surface roughness of only a few tens of micrometers. Even laser cutting can be used as the final process, without the need for mechanical processing, and the parts can be directly used.
③ After the material is cut by laser, the width of the Heat-affected zone is very small, and the performance of the material near the notch is almost unaffected. The deformation of the workpiece is small, the cutting accuracy is high, the geometric shape of the notch is good, and the cross section of the notch is a regular rectangle.
(3) Fast cutting speed.
When laser cutting, there is no need to clamp and fix the material, which not only saves tooling fixtures but also saves auxiliary time for loading and unloading.
(4) Non contact cutting.
During laser cutting, there is no contact between the welding torch and the workpiece, and there is no tool wear. To process parts of different shapes, there is no need to change the “tool”, only the output parameters of the laser need to be changed. The laser cutting process has low noise, low vibration, and no pollution.
Modern metal laser cutting technology has become quite mature and has gradually become a “sharp sword” for people’s fantasy of “cutting iron like mud”.
