Many users and friends of laser cutting machine consulted, why does the laser cutting opportunity cause the deformation of the cut metal? In fact, this problem is one of the common problems of laser cutting machines, so don’t be too nervous. So, why does the laser cutting cause the metal being cut to deform?

1. First, let’s check: Whether the laser cutting machine reference is not set correctly, for example: Is it caused by the laser cutting machine’s dimming not being adjusted properly?

2. Secondly, we need to see what raw materials are used for cutting. The reflective properties and metal properties 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. Although the laser cutting machine has relatively small thermal deformation compared to the flame cutting machine and the plasma cutting machine. But it is still deformed.

3. The size of the deformation has a lot to do with the cutting material, 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.

Now you should know the reasons of metal thermal deformation in laser cutting. In next article we will introduce specific measures to avoid it.
