With the wide use of optical fiber laser cutting machine, it is more and more familiar to customers, but we often encounter some problems in the process of operation, such as the problem of edge burning when laser cutting sheet metal parts, so how does this happen? Let’s look at it together.
First of all, the optical fiber laser cutting machine will generate a lot of heat when cutting the sheet metal by laser. Generally, the heat generated by cutting will spread along the cutting seam to the processed sheet metal for cooling. But sometimes when we cut small holes, the outside of the hole can be cooled. The small hole part inside the single hole is caused by over burning and slag hanging due to the small space where the heat can spread and the excessive concentration of energy;
Secondly, in cutting thick plates, the molten metal accumulated on the material surface during perforation and the heat accumulation will lead to the disorder of auxiliary air flow and excessive heat input, which will lead to over burning.
Of course, this is only part of the reason for the edge burning of the optical fiber laser cutting machine. We need to constantly summarize and accumulate experience and lessons in the actual operation process.
