In modern industrial production, fiber laser cutting machines have become an efficient and accurate cutting tool. However, many users may encounter a problem - a decrease in power for fiber laser cutting machines. So, what is the reason for this? How should we solve it again?
1、 Inappropriate focus position
The focus position has a crucial impact on the cutting accuracy and speed of fiber laser cutting machines. If the focus position is not appropriate, it will cause the focal length of the cutting head to shift, increase the cutting line width, reduce the cutting speed, and thus affect the cutting effect. Solution: Adjust the focus position and select the appropriate focus distance based on the actual cutting material thickness and material.
2、 The distance between the nozzle and the workpiece is not appropriate
The distance between the nozzle and the workpiece is too far, which can lead to an increase in cutting line width and waste of energy; If the distance is too close, it will affect the dispersion of splashing cutting products, thereby affecting the cutting effect. Solution: Adjust the distance between the nozzle and the workpiece, usually around 0.8mm.
3、 Power attenuation of fiber laser cutting machine
Over time, the laser of the fiber laser cutting machine may experience power attenuation. This may be caused by factors such as aging and improper maintenance of the laser. Solution: Regularly check the usage of the laser and replace aging laser components in a timely manner; At the same time, regular maintenance and upkeep should be carried out on the laser to maintain its good working condition.
4、 Cutting speed too fast
The cutting speed is directly proportional to the power of the fiber laser cutting machine. If users blindly increase the cutting speed during the cutting process, it may lead to insufficient power and affect the cutting effect. Solution: Choose the appropriate cutting speed based on the actual cutting material thickness and material.
5、 Long term load production, lack of maintenance
Long term load production and lack of maintenance are common reasons for the performance degradation of fiber laser cutting machines. Long term continuous operation and lack of necessary maintenance can lead to a decrease in machine performance and power. Solution: Reasonably arrange production plans to avoid prolonged continuous machine operation; At the same time, regular maintenance and upkeep should be carried out on the machine to ensure its good working condition.
