With the development of laser cutting technology, optical fiber laser cutting machine has been widely used. What impact will laser cutting machine have on cutting rusty plates?
1. Cutting rusty plates will reduce the processing efficiency, reduce the cutting quality, and increase the product scrap rate accordingly. Therefore, if conditions permit, use less rusty plates or treat them before using them during sheet metal processing.
2. In the process of plate cutting, especially when punching and cutting, holes may burst, which will pollute the protective lenses. This requires us to deal with the rusty plates first. If we use a grinder to remove rust, of course, the impact of plates below 5MM is not significant, mainly rusty thick plates, but the cutting quality will still have an impact, which is not comparable to the quality of cutting qualified plates.
3. The overall uniform cutting is better than the uneven rusty plate, and the overall uniform rusty plate absorbs laser relatively evenly, so it can be better cut. For uneven rusty sheet metal, it is recommended to treat the surface, even the sheet metal surface, and then conduct laser cutting of sheet metal.
In addition to the problem of cutting plates, attention should also be paid to the following reasons for the decline of the cutting performance of the optical fiber laser cutting machine because of the loss caused by the long-term use of the optical fiber laser cutting machine, which affects the cutting performance
1. Power: After the machine is used for a long time, the laser power will drop more or less, which will directly affect the cutting performance of the laser cutting machine;
2. Distance: The distance between the processing workpiece and the nozzle also affects the cutting effect of the laser cutting machine, so it is necessary to adjust the appropriate distance without affecting the performance of the cutting;
3. Position: The focus position directly affects the cutting progress. The diameter of the focus spot should be as small as possible to produce narrow slits. If the cutting performance declines, it is a good method to adjust the focus position;
4. Overloaded production for a long time, no maintenance and improper operation by operators are the reasons for the decline of cutting equipment performance.
To sum up, it is easy to find out the reasons for the decline of laser cutting machine performance, so we can take preventive measures to effectively avoid or slow down the decline of cutting performance in a timely manner
