As the name would imply, laser cutting uses a laser, which is a precisely focused, high-intensity beam of light. Think about using a magnifying glass to focus the sun’s rays onto a leaf, and how that can start a fire. Northampton On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. Applications Popular industries using the laser systems for all types of engraving and cutting work. As the laser beam travels from the laser resonator through the path of the machine, it may be focused by a special mirror, lens, curved mirror or beam bender onto a working cutting point on the object. So how exactly does laser cutting work? We also offer advice, so if you’re not sure what the right machine is for you, or wish to know the benefits of each in more detail, we’d be glad to help. Laser cutting machine is a cutting technology that uses laser characteristics and lens focusing to concentrate energy to melt or vaporize the surface of the material. As the lasing material is stimulated, the beam is reflected internally by means of a partial mirror, until it achieves sufficient energy to escape as a stream of monochromatic coherent light. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Laser cutting is the process of precisely cutting or engraving a material using focused high-powered laser beam, directed by CNC (Computer Numerically Controlled) machine from a CAD vector file. The high power density results in rapid heating, melting and partial or complete vaporizing of the material. CTR Lasers also lists a wide range of materials compatible with the machines and if the material isn't listed, just take advantage of the 'send a sample' service on any specialist materials for expert advice. 1.
