How to avoid metal deformation during laser cutting machine cutting process?

The cutting process of laser cutting machine will cause the deformation of the cut metal, which is one of the problems that customers often encounter. Is the laser cutting machine reference set right? Or is the laser cutter improperly operated? Or is it another reason? Why does laser cutting cause deformation of the cut metal? How to avoid metal deformation? Today, oree engineers combine years of cutting experience to do the following analysis:

How to avoid metal deformation during laser cutting machine cutting process?(图1)



  First of all, let's check if it is caused by the improper dimming of the machine.

  The second analyzes what raw material is used for cutting. The reflective characteristics and metal characteristics of the raw material 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 largely determines the size of the deformation.

  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, which causes the switch to change.
