Laser cutting machine to ensure process stability of solution at present in order to improve the speed of processing machine, laser cutting machine used more commonly known as flying light path structure, namely the material tray still while the processing head movement forms can be processed in the whole area.
And to compensate for the processing and the change of the light source, relative position, the manufacturer also as far as possible to ensure the consistency of the flare in the processing scope, using variable refractive lens curvature is a popular choice.
Although this method has simple structure but will change zoom deep, make in focusing deep sensitive plate will be ragged (
Should not only keep unchanged spot and the focal depth unchanged)
。
Using length of light path (
Within the scope of the machinable between light source and the processing head light propagation path length)
Can avoid the depth change, so that the light spot and the focal depth is consistent.
In addition to into the attention of the hot plate heat accumulation under control, better solve the stability problem.
