Laser cutting is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the laser beam will melt or gasify the metal away. As an indispensable processing method in the field of modern industrial manufacturing, laser cutting is not only fast and efficient, but also has a very good effect. With the relative position of the beam and the workpiece moving, the material finally forms a cutting seam, so as to achieve the purpose of cutting.
At present, the largest cutting capacity of laser cutting in industrial application: the carbon steel is 36mm, the steel plate quality is good, and the speed can be about 650mm / min. if the 36mm steel plate material is good, the machine is good, and the graphics are not very complex, the cutting quality is still good. Generally, the hole size is related to the plate thickness, and the average diameter of the blasting hole is half of the plate thickness. Therefore, the hole diameter of the blasting hole of the thicker plate is larger and not round, which is not suitable for the parts with higher processing accuracy requirements, and can only be used for waste materials.
Stainless steel is 25 mm. When using high-pressure nitrogen as auxiliary gas, the speed is relatively slow about 400 mm / min. however, domestic users generally aim at laser cutting, with low carbon steel below 25 mm and stainless steel below 16 mm. The selection of the laser head nozzle does not match the thickness of the processing plate, the laser cutting line speed is too fast, the operation control is required to reduce the line speed, the nozzle induction is not allowed to lead to the laser focus position error is too large, it is necessary to re detect the nozzle induction data, especially when cutting aluminum.
Laser cutting uses invisible light beam instead of the traditional mechanical knife. The mechanical part of the laser knife head has no contact with the work and will not scratch the working surface during the work. The laser cutting speed is fast, the incision is smooth and flat, generally no subsequent processing is required. The cutting heat affected area is small, the plate deformation is small, and the cutting seam is narrow (0.1mm ~ 0.3mm).
Generally, the 1000W fiber laser cutting machine can cut about 10 mm carbon steel plate, and the stainless steel plate is a little difficult to cut. To improve the cutting thickness, it is necessary to sacrifice the edge effect and speed. For different metal materials, the cutting thickness of different power metal laser cutting machine has a great relationship with the cutting materials.
