ABSTRACT:
A laser cutting machine consisting of a focusing head; an exit nozzle; a joint structure which supports the head; a control unit; a drive device, which is supported by a joint structure and controlled by a control unit to move the head along a specified path in space, whereby a theoretically determined, invariant distance is maintained between the exit nozzle and a plate material to be cut, the head having first and second portions which can move relative to each other in the axial direction; a servomechanism, one end of the portions being coupled to the nozzle and a focusing lens, whereby while the machine is in use, the servomechanism controls the relative motion of the two portions in the axial direction independently of the control unit to maintain a specified and invariant distance between the nozzle and the surface.
