Reasons and solutions for power reduction of fiber laser cutting machine
In modern industrial production, fiber laser cutting machines have become an efficient and precise cutting tool. However, many users may encounter a problem – the power of fiber laser cutting machines decreases. So, what is the reason for this? How can we solve it? Today, Yiqiang editor will give you a lecture.
1、 Inappropriate focus position
The focal position has a crucial impact on the cutting accuracy and speed of fiber laser cutting machines. If the focal position is not appropriate, it will cause the focal length of the cutting head to shift, resulting in an increase in cutting line width and a decrease in cutting speed, thereby affecting the cutting effect. Solution: Adjust the focus position and select the appropriate focus distance based on the actual cutting material thickness and material.
2、 Inappropriate distance between nozzle and workpiece
The distance between the nozzle and the workpiece is too far, which can increase the cutting line width and waste 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 due to aging of the laser, improper maintenance, and other reasons. Solution: Regularly check the usage of the laser and replace aging laser components in a timely manner; At the same time, regularly maintain and upkeep 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 thickness and material of the cutting material.
5、 Long term load production and 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 output. Solution: Reasonably arrange production plans to avoid prolonged continuous operation of machines; At the same time, regularly maintain and upkeep the machine to ensure its good working condition.
In summary, the main reasons for the decrease in power of fiber laser cutting machines include inappropriate focus position, inappropriate nozzle distance from the workpiece, laser power attenuation, excessive cutting speed, long-term load production, and lack of maintenance. Users can investigate the problem one by one according to the actual situation and take corresponding measures to solve it. In addition, it is recommended that users choose products with reliable quality and mature technology when purchasing fiber laser cutting machines to ensure the performance and stability of the machine.
