Below is a list of Laser Cutting manufacturers from Lisle, Illinois. Laser cutting is a low-distortion hot cutting process that most commonly uses a CO2 laser for the cutting of material, which is usually metal. “Laser” is an acronym for Light Amplification by Stimulated Emission of Radiation. The beam of the laser is an extremely focused radiation of a wavelength, meaning the beam will not dissipate like conventional light beams.
