Laser cutting machine in order to reduce the focus beam size change before the change of the focal spot size, domestic and foreign manufacturers of laser cutting system provides some special device for users to choose:
( 1) 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.
（ 2) Flat tube. 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.
