Laser cutting machine in order to reduce the focus beam size change before the change of the focal spot size of the device: (
1)
Parallel light pipe.
This is a commonly used method, that is, at the output of the CO2 laser beam expander of parallel light pipe processing, expanded beam after the beam diameter, divergence Angle smaller, so in cutting work within the scope of the proximal and distal focused beam size close to agreement before.
（
2)
Increase in the cutting head under a separate mobile lens axis, it and control the nozzle to the material surface distance (
站)
The Z axis is part two independent of each other.
When the machine table to move or optical axis direction, the beam from the proximal to distal F axis move at the same time, also make the light beam focusing spot diameter after consistent throughout the processing area.
As shown in figure 2.
（
3)
Control focusing mirror (
General focus for metal reflection system)
The water pressure.
If before the focus beam size smaller and make the focal spot diameter larger, automatic control water pressure change focus curvature makes focal spot diameter smaller.
（
4)
Flight path on cutting machine increases the x and y direction to compensate the light path system.
Namely to make compensation when cutting the remote optical path to increase the light path shortened;
Conversely when cutting proximal reduced optical path, increase the light path compensation, to keep the optical path length
