Laser engraving and cutting machine is widely used in modern production.
At present there are three main types: fiber laser cutting machine, CO2
laser cutting machine, YAG laser cutting machine.
Fiber laser cutting machine can pass through the optical fiber, and it with
few fault points while quick cutting sheet within 6MM. But it is not good at
cutting more than 12MM thick plate. Because laser wavelength of fiber
laser is 1.06UM, it can not cutting nonmetallic materials. 
The fiber laser cutting machine photoelectric conversion rate reaches
more than 25%, in electricity consumption, supporting the cooling system
and other aspects of fiber laser cutting machine advantage is quite
obvious. According to international safety norms, laser hazard grade is
level 4. Due to the short wavelength, the fiber laser large cause damage
on the human body especially the eyes. So the fiber laser processing
need full blockade of the environment.
As a new laser technology of fiber laser cutting machine, it is less
popular than CO2 laser cutting machine.
