What is the reason for the laser cutting opportunity to cause the deformation of the cut metal

The laser cutting machine can cause deformation of the metal being cut, which is also one of the common problems of laser cutting machine. Is the laser cutting machine reference not set correctly? Or is the laser cutting machine improperly operated? Or is it another reason? Why laser cutting machine Leading to the deformation of the cut metal? Bystronic can combine years of cutting experience to make the following analysis:

　　 First, let's check if it is caused by the improper dimming of the machine. The second analysis of the raw materials used for cutting, the reflective characteristics and metal characteristics of the raw materials may affect the cutting effect. If you are cutting thin metal plates, laser cutting is thermal cutting, and thermal cutting will definitely be deformed. Compared with flame cutting machine and plasma cutting machine, the deformation is relatively small. But there is still deformation. The size of the deformation has a lot to do with the material being cut, the shape of the part, the cutting thickness, and the laser processing technology. The shape of the part determines the size of the deformation to a large extent. For example, if you cut a square, the thermal deformation will not be too large. But if you cut a long and narrow rectangle (10*2000mm), the deformation will definitely be great. The reason for the deformation is due to uneven heating, which causes thermal expansion and contraction to cause the switch to change.
