Waterjet cutting can be used to slice through most materials and is a process that does not give off hazardous vapours or waste. Laser cutting involves the focusing of a laser beam directly at a material to achieve a cut. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. A capacitive height control system maintains a very accurate distance between the end of the nozzle and the metal that is being cut. Terms and Conditions With a tiny kerf width and heat affect zone laser cutting enables us to cut very intricate shapes and tiny holes. It may be bounced in different directions by a number of mirrors, or “beam benders”, before it is finally focused onto the plate. The high power density results in rapid heating, melting and partial or complete vaporization of the material. The parallel laser beam is thus only a few millimetres underneath the cutting nozzle, focussed on the top of the material being processed. For CO2 lasers, the single wavelength is in the infrared part of the light spectrum and it's invisible to the human eye. How Does Laser Cutting Work? The laser beam itself is a column of high intensity light. Focusing the laser beam can be done by a special lens, or by a curved mirror, and this takes place in the laser cutting head. Laser cutters carefully orient the laser cutting head to facilitate the melting and cutting action. 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. 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 laser handles all the burning and cutting, while the nitrogen blows the kerf free of molten metal remains. Why lasers are used for cutting Lasers are used for many purposes. This process is so accurate and time efficient, it has become a necessity for many businesses.

It not only provides superlative flexibility but is competent of moulding metals into most complex designs. Cutting Systems The beam itself is only roughly 3/4 of an inch in diameter and this travels from the laser resonator, creating the beam through the machines beam path. Laser cutting in recent application Laser cutting is a technology that uses a laser to slice materials. This distance is important, because it determines where the focal point is relative to the surface of the plate. Laser cutting is an industry standard for accurate, fast fabrication. One way they are used is for cutting metal plates. Mirrors or fiber optics are typically used to direct the coherent lightto a lens, which focuses the light at the work zone. Units 5-6, Sterling Business Park Excimer lasers (the name is derived from the terms excited and dimers) use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon. Northampton At the start of the laser cutting process, the laser device creates a beam of light and directs it towards the outlet via mirrors. When cutting mild steel, the heat of the laser beam is enough to start a typical “oxy-fuel” burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. Intensifier or direct drive pumps get the water to the high pressure needed for cutting. But what exactly is a laser, how does it work, and how do we use it to do some everyday amazing things? So, how does light have the power to cut through thick steel plate? The advantages of a laser when cutting. Once the laser beam has completely penetrated the material at one point, the actual cutting process begins. In addition to the CO2 machines, CTR Lasers offer a rapidly increasing range of British designed and manufactured laser and engraving machines, these including metal cutting machines and microstep machines. Were you aware that the word, “LASER,” is actually an acronym for Light Amplification by Stimulated Emission of Radiation? A laser cutter, on the other hand, uses a longer focal length, which allows for cutting thicker materials with a more precision cut and at faster speed. Laser cutting technology refers to the use of a laser beam to cut materials. Laser cutting in metal fabrication provides a large of benefits that traditional methods can not. These are then focused through the plate and pass the nozzle to hit the surface, which is to be cut. When electrically stimulated, a pseudo molecule (dimer) is produced. In layman’s terms, laser cutting refers to a thermal process where a focused laser beam melts materials. It bounces in different directions off mirrors, or more professionally known as beam benders, finally focusing on the material that you’d like to cut. So how exactly does laser cutting work? CNC lasers, the laser cutting head moves over the sheet metal in the shape of the desired part.
