In the actual operation of our fiber laser cutter for precision metalworking, the laser generally has three operating modes: continuous mode, modulation mode, and pulse mode.
When using China 150w qcw fiber laser cutting machine, in continuous mode, the power output of the laser is constant, which makes the heat entering the sheet more uniform, which not only improves work efficiency, but also avoids the tissue deterioration of the heat-affected area caused by heat concentration. For our China 150w qcw fiber laser cutting machine, the laser power of the modulation mode is a function of the cutting speed. It can effectively prevent the edge of the cutting seam from burning, but due to the complex control and low efficiency, it is only suitable for fine processing tasks in a short period of time. As for the pulse mode, our China 150w qcw fiber laser cutting machine will make choices according to different material properties and structural accuracy requirements.
In terms of the selection of protective gas, no matter what type of precision fiber laser cutting machine it is, it will involve the selection of laser working gas, protective gas, and auxiliary gas.For example, when cutting stainless steel and high-strength steel, our China 150w qcw fiber laser cutting machine uses nitrogen as a protective gas to prevent oxidation and blow away the melt; for thick plate cutting, high-speed cutting and very thin plate cutting, oxygen will be considered; in addition, air is also used for cutting aluminum, non-metallic and galvanized steel plates, which not only reduces the formation of oxide film, but also reduces costs.
In the process of using our fiber laser cutter for precision metalworking, the speed of laser cutting can theoretically reach up to 40m/min, but in actual processing, it can often only reach 1/3-1/2 of the maximum speed, because the speed is too high will cause the dynamic accuracy of the servo mechanism to decrease, which in turn affects the cutting quality. Especially when using our folding crotch press fiber laser cutter for precision metalworking to cut round holes, the faster the cutting speed, the smaller the aperture, and the worse the roundness of the processing. Therefore, when cutting in a long straight line, the maximum cutting speed of fiber laser cutter for precision metalworking can be appropriately increased to improve efficiency. According to the material, thickness and technical requirements of the product, the operator needs to adjust the laser power, air pressure and other parameters of the fiber laser cutter for precision metalworking to find the cutting speed that best suits your product.
