Cutting kerf big reason of problem solving method

Cutting kerf big reason of problem solving method. Laser cutting machine in the process to meet big problem how to solve the kerf width, what is the cause of their occurrence. Here the results of the analysis are: 1. Check to see if there is something wrong with the focal length, and should pay attention to clean lens and replace a new lens focal length change, the adjustment shall be the focal length of the correct value! 2. Lens is one of key reasons, carefully check whether the lens is damaged or dirt, because such a situation can lead to the laser scattering, lead to laser beam coarsens, replacement or cleaning the lens is the only way. 3. Factors of laser tube is also cannot be ignored, and check the quality of the laser tube light mouth there out, if there is a point or points of light is not round, the phenomenon such as hollow, as the supporting point of the laser tube, is right direction. The solution is the need to adjust the support, rotation, replace the laser tube.
