1. The focus position will affect the cutting accuracy, especially the focus diameter. The focus diameter should be as small as possible to form a narrow slit, and the focus diameter is proportional to the focus depth of the focus lens, and the smaller the focus depth, the smaller the focus diameter.
2. The distance between nozzles and the distance between workpiece and nozzle will also affect the power of fiber laser cutting machine. Too long distance will lead to unnecessary waste of kinetic energy, and too close distance will affect the diffusion ability of spatter cutting products. The appropriate distance is 0.8 mm. In addition, the fiber laser cutting machine can mainly cut the workpiece with uneven surface through the following adjustments, and the height of the nozzle and the workpiece should always be the same during operation.
3. The cutting speed has a great influence on the power of the fiber laser cutting machine, and the cutting speed is directly proportional to the power of the fiber laser cutting machine. At the same time, the quality of cutting is related to the quality of laser beam and the characteristics of laser beam focusing system. That is, the size of the focused laser beam has a great impact on the laser quality.
4. Auxiliary gas, auxiliary gas and gas pressure will also affect the power of fiber laser cutting machine. Compressed air or nitrogen is recommended as auxiliary gas. If the thickness of the material increases or the cutting speed is slow, the air pressure should be reduced appropriately. Use low-pressure cutting to prevent frosting of edge cutting.
