A laser cutting machine works by focussing a beam of laser light onto a piece of material. How does it work? In laser machining, a computer directs a high power laser to cut out the desired shape from stock material. Depending on the exposure time, a contrast can be created as the colour changes, or the material evaporates or burns. 1. There is a nozzle that the focused laser beam goes through and also passing through this nozzle is a compressed gas, such as oxygen or nitrogen. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. Laser cutting is an industry standard for accurate, fast fabrication. 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. Now that you understand how does a laser cutter work and you know the advantages it gives you, you can tell how beneficial it will be for your manufacturing process. Think about using a magnifying glass to focus the sun’s rays onto a leaf, and how that can start a fire. 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. The achieved laser engraving result is … Intensifier or direct drive pumps get the water to the high pressure needed for cutting. A co2 Laser for example uses focusing lenses; where as a Fiber Laser delivers the beam through a fibre-optic cable. Laser cutting is a type of thermal separation process.

This site uses cookies and other tracking technologies to provide you with our services, enhance the performance and functionality of our services, analyze the use of our products and services, and assist with our advertising and marketing efforts. There is a clever acronym for the word ‘laser’, five words which make it easier to define; Light Amplification by Stimulated Emission of Radiation. The laser … The parallel laser beam is thus only a few millimetres underneath the cutting nozzle, focussed on the top of the material being processed. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. At the start of the laser cutting process, the laser device creates a beam of light and directs it towards the outlet via mirrors. We all know the importance of laser tubes in laser equipment clearly. How Does Laser Cutting Work? When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. In layman’s terms, laser cutting refers to a thermal process where a focused laser beam melts materials. This distance is important, because it determines where the focal point is relative to the surface of the plate. 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. For CO2 lasers, the single wavelength is in the infrared part of the light spectrum and it's invisible to the human eye. United Kingdom A laser cutter is a prototyping and manufacturing tool used primarily by engineers, designers, and artists to cut and etch into flat material. How does a laser cutting machine works? Laser cutting works by directing the output of a high-power laser most commonly through optics. A laser cutter uses an extremely powerful beam of focused light and projects this onto a sheet of material. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. 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. Legal Notice Essentially a laser cutting is part of the fabrication process used to cut materials in custom designs, using a laser beam. 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 gives you a lot of design freedom, plenty of material options and can be combined with other methods giving you the best results. It's no doubt thanks to these sorts of stories that we now associate lasers with futuristic warfare and sleek spaceships. The beam is focused onto the surface by different means dependent on the laser. The process works by having a focused and precise laser beam run through the material that you are looking to cut, delivering an accurate and smooth finish. 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. \"Star Wars,\" \"Star Trek,\" \"Battlestar Galactica\" -- laser technology plays a pivotal role in science fiction movies and books. How does laser cutting work? How Does Laser Cutting Work? It yields excellent cut quality and has a very small kerf width and small heat affect zone. So how exactly does laser cutting work?
