Optical fiber laser metal cutting machine has become an indispensable tool for sheet metal processing enterprises. Its advantages such as high-precision steel plate cutting and high power conversion efficiency are the reasons why optical fiber laser cutting machine can quickly occupy the market. Usually, when we use the metal fiber laser cutting machine for processing, we occasionally encounter some problems, such as the gap between steel plate cutting is too large, or the accuracy of the processed parts is reduced, which can not meet customer requirements. How to deal with this sudden failure?
1. Due to various reasons, the surface of the object to be processed may be uneven, and a large amount of heat will be generated during the processing of the laser cutting machine, which may cause deformation of the surface of the thin plate and the surface of the workpiece to be processed. The random change of the focus of the non-uniform laser cutting machine and the surface of the object to be processed will cause the failure of excessive cutting clearance or incorrect processing.
2. The error is caused by incorrect installation of the optical fiber laser cutting machine. Place the workpiece on the workbench of the metal fiber laser cutting machine. An error will occur due to the incorrect position of the workbench. If the equipment is not firmly installed, and the parts are worn for a long time, the stress on the workbench surface will be uneven. This imbalance will also cause random errors between the thin steel plate and laser focusing, resulting in excessive cutting clearance or reduced processing accuracy.
3. Errors caused by programming. In the process of optical fiber laser cutting machine, the complex workpiece surface processing path diagram is composed of multiple models such as straight lines and arcs. Professional software is required for drawing. Some software programming systems also include some errors, which can be avoided to the greatest extent by using genuine software.
4. Focus position error occurs in laser cutting. In the process of optical fiber laser cutting machine, there are many factors that cause the relative position of the focus and the cutting object surface to change. These random errors cannot be avoided, and can only be reduced through online detection and control to ensure the processing accuracy of optical fiber laser cutting machine.
5. Regularly check whether there is a problem with the focal length of the fiber laser cutter, especially after cleaning the lens or a better new lens.
6. Check whether the lens of the metal optical fiber laser cutting machine is damaged or polluted, because these problems will cause laser scattering, resulting in excessive cutting clearance or reduced processing accuracy of the laser cutting machine. Please replace or clean the lens in time as an effective solution.
7. The quality of the laser tube is also a factor that cannot be ignored. Check the quality of the laser spot. If there are bright spots or non-circular or hollow spots, the solution is to adjust the support, rotation direction or replace the laser tube.
In a word, optical fiber laser metal cutting machine often has some faults in the process of use. The most common effect of these failures is to reduce machining accuracy or cause excessive cutting clearance. These conditions will affect the production of enterprises. Causing adverse effects or unnecessary waste. This requires us to do a good job of equipment maintenance in our daily work to ensure the efficient and lasting operation of the laser cutting machine, so that the optical fiber laser cutting machine can create the maximum value for the enterprise.
