What is the core technology of metal laser cutting machine

The market demand for metal laser cutting machines is currently very large, and the application of metal laser cutting machines is also very extensive. So what is the core technology of the metal laser cutting machine? This is a question that everyone needs to figure out. Next, let's take a look together. The core technology of 　　 metal laser cutting machine is the focus position control technology: one of the advantages of 　　 laser cutting is the high energy density of the beam, generally>10W/cm2. Since the energy density is proportional to 4/u0026pi;d2, the focal spot diameter is as small as possible to produce a narrow slit; at the same time, the focal spot diameter is also proportional to the focal depth of the lens. The smaller the focal depth of the focusing lens, the smaller the focal spot diameter. However, there are spatters in cutting, and the lens is too close to the workpiece to damage the lens. Therefore, the focal length of 5'～7.5' (127～190mm) is widely used in general high-power CO2 laser cutting industrial applications.　　The actual focal spot diameter is between 0.1mm and 0.4mm. For high-quality cutting, the effective focal depth is also related to the lens diameter and the material being cut. For example, cutting carbon steel with a 5' lens, the focal depth is within +2% of the focal length, which is about 5mm. Therefore, it is very important to control the position of the focus relative to the surface of the material to be cut. Taking into account factors such as cutting quality and cutting speed, in principle, the focus is on the surface for metal materials <6mm; the focus is on the surface for carbon steel>6mm; and the focus is on the surface for stainless steel>6mm. The specific size is determined by experiment.　　 Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete equipment.
