After using the laser cutting machine for a long time, many people will find that the power of the laser cutting machine has declined. Why is this? Next, let ’s follow the Sichuan cutting equipment manufacturer Xiaobian to discuss it!
1. Focus position will affect cutting accuracy, especially focus diameter. The focal spot diameter should be as small as possible to create a narrow slit, and the focal spot diameter is proportional to the focal depth of the focusing lens, and the smaller the focal depth, the smaller the focal spot diameter.
2. The distance of the nozzle and the distance between the workpiece and the nozzle will also affect the power of the fiber laser cutting machine. Too long a distance will cause unnecessary waste of kinetic energy, and too close a distance will affect the diffusion ability of splash cutting products. The proper distance is 0.8 mm. In addition, the fiber laser cutting machine can cut the workpiece with uneven surface mainly through the following adjustments, and the height of the nozzle and the workpiece should always be the same during the operation.
3. The cutting speed has a great influence on the power of the fiber laser cutting machine, and the cutting speed is proportional to the power of the fiber laser cutting machine. At the same time, the cutting quality is related to the quality of the laser beam and the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the cutting speed of the laser quality.
Auxiliary gas, auxiliary gas and gas pressure will also affect the power of the fiber laser cutting machine. It is recommended to use compressed air or inert gas as auxiliary gas. If the thickness of the material increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Cutting with low pressure prevents frost on the edges.
If the first four items are excluded, consider the reduction in laser power. Part of the aging phenomenon will occur after long-term use of any equipment. Laser is the core component of fiber laser cutting machine. In addition to the above points, the performance, size and thickness of the processed material will also affect the power of the fiber laser cutting machine.
