Laser machining device and method and elastic net face material laser machining method

The invention relates to a laser machining device and method and an elastic net face material laser machining method. The laser machining device comprises a rack, a displacement mechanism and a machining mechanism. The machining mechanism comprises a laser device, a guider drive piece and a guider which are all arranged on the displacement mechanism and can be driven by the displacement mechanismto move relative to the rack. The guider is connected to the guider drive piece and can be driven by the guider drive piece to rotate. The guider can reflect lasers emitted by the laser device, the guider reflects the lasers to different positions of a to-be-machined product through rotation, and the to-be-machined product is cut. According to the provided laser machining device, the guider rotates and reflects the lasers so that the detailed structure machining equipment can be met, the rotation angle and the rotation speed of the guider can be conveniently controlled through the guider drivepiece, and the manufactur
