The working principle of laser cutting machines relies on high-energy focusing and precise control of laser beam. Lasers generate this beam which then has to be focused into an extremely small spot using lenses or focussing lenses to cut material accurately and precisely. By manipulating both its position and intensity of laser beam, a laser cutter can produce cut lines of various sizes on any material surface. Laser beam heating rapidly melts material, while assisted gas blowing quickly removes it to form precise cutting edges. An accurate control system ensures stability and precision during cutting processes - making laser cutting machines reliable tools.
