5mm) faster than a fibre laser of the same power. It all begins from the moment we receive an inquiry and continues through to the shipment of the manufactured parts. The lens is defined by its focal length, which is the distance from the lens to the focused spot. The Laser Cutting Process: Analysis and Applications presents a comprehensive understanding of the laser cutting process and its practical applications. Fibre laser sources have the following advantages: Direct diode laser technology is the latest progress in the field of solid-state lasers. We use CO 2 machines. These dents and holes are essentially cuts, and you’ll often see a cutting laser machine also being used for drilling and engraving too. Those used for material processing can generate beams of many kilowatts in power. In 1979, the Italian company Prima Industrie invented the first 3D laser-cutting process with a 5 axes rotation system. CO2 lasers typically emit at a wavelength of 10.6μm. Simply put, laser cutting is the process of using a laser to cut, score, engrave or otherwise alter physical materials. The only other consideration is that the shorter the focal length, the closer the lens is to the workpiece, and therefore more likely to get damaged by spatter from the cutting process. Direct diode lasers at multi-kilowatt levels of power are commercially available and have been successfully used for sheet metal cutting applications. This reflection does not come entirely from the sheet surface, but is caused by the formation of a molten pool which can be highly reflective. The gas in question is a carbon dioxide mixture which has been electrically stimulated. As the workpiece is not moved, this also means that there is no real limit to sheet weight. In remote cutting, the material is partially evaporated (ablated) by a high-intensity laser beam, allowing thin sheets to be cut with no assist gas. Image credits: SD-Pictures, moritz320 and PeteLinforth. Laser cutting is a fabrication process which employs a focused, high-powered laser beam to cut material into custom shapes and designs. Fibre lasers are a member of a family called ‘solid-state lasers’. Once the laser beam has completely penetrated the material at one point, the actual laser cutting process begins. We manufacture  both Pulsed Fiber and Continuous Wave (CW) Fiber Lasers to complete any cutting tasks. It also means that they can work with both metal and non-metal materials.\n\nA fiber laser is the most useful of the three types. For a constant focus length lens, increase in the raw beam diameter also reduces both the spot diameter and the depth of focus. The wall-plug efficiency of CO2 lasers is about 10%, which is higher than for most lamp-pumped solid-state lasers (eg ND:YAG lasers), but lower than for many diode-pumped lasers . This method uses nd:YAG (neodymium-doped yttrium aluminium garnet) and nd:YVO (neodymium-doped yttrium ortho-vanadate) lasers. When it hits the workpiece, the material heats up to the extent that it melts or vaporizes. A laser cutter is an equipment or machine that is used to engrave and cut materials using laser technology. The process simply involves the use of a focused laser beam (e.g. Laser technology has the following advantages: High accuracy Read our Fiber laser cutting infographic to learn more about the laser cutting process, end to end.

laser cutting process

They have the same wavelength as above, 1.064 micrometres. In doing so, the oxygen is blown into the kerf at pressures of up to 6 bar. However, for the same reason, direct diode lasers are currently of lower beam quality compared to fibre lasers. The laser beam is then transmitted through an optical fibre where it gets amplified (similar to a conventional laser cavity in CO2 lasers). b) long depth of focus to process thicker materials with a reasonable tolerance to focus position variation. As futuristic as it sounds, laser cutting is a technology that has been with us for decades. Unlike fibre lasers, direct diode lasers do not include a brightness-enhancing stage, giving them lower optical losses and higher wall-plug efficiency. Laser cutting is a kind of non-contact machining with high energy and density control The laser beam is focused to form a light spot with high energy density. A vast range of materials and thickness sizes can be cut with lasers, making it a handy and adaptable process. These benefits have led to laser-based cutting being used in numerous industries, including the automotive (including e-mobility), aerospace, electronics, semi-conductor and medical industries to name just a few. This means that it can easily cut light materials such as cloth up to tougher metals and gemstones such as diamonds. C02 cutting is most often used on non-metal materials as they have a wavelength of 10.6 micrometres. This can be for small & fine materials or materials with a much greater level of thickness (e.g. Laser cutting is completed using a laser such as this, {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is laser cutting? 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. Fusion cutting is another standard process used in metal cutting, and it can also be used to cut other fusible materials, such as ceramics.. There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting. The objective of this paper is to provide a state of the art in the field of laser cutting process. Initially, the beam pierces the material with a hole at the edge, and then the beam is continued along from there.\n\nThe laser essentially melts the material away that it is run over, so is more like melting than cutting. In this technology, several laser beams emitted from laser-emitting diodes of different wavelengths are superimposed using so-called beam combining techniques. You can control the beam intensity, length and heat output depending on the material you are working with, and can also user a mirror or special lens to further focus the laser beam. The former involves the creation of thru-holes in a material or dents, like an engraving used in the later process. The most popular approach is known as a 'flying optics' system, where the workpiece remains stationary and mirrors are moved in both X and Y axes. Alongside the benefits listed above, they are often maintenance free, require much cheaper replacement parts, and have a much longer service life of around 25,000 usage hours. To make this a little easier, we have explored the process in greater detail below, looking at how the process works, the different types of laser cutting, its advantages, and where you’ll see it most commonly used. ","acceptedAnswer":{"@type":"Answer","text":"C02 laser cutting\nC02 cutting is achieved using a gas laser. Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area.

","acceptedAnswer":{"@type":"Answer","text":"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. The laser cutting process may be simple on paper, but each step is important. It has many features when applied in the cutting process. The crystal used also has a much shorter service life than that of a fiber laser.\n\nFiber laser cutting\nThis type of cutting is completed using a fiber laser, the type we manufacture here at SPI Lasers. Cutting • Laser cutting is able to cut faster and with a higher quality then competing processes: – Punch, plasma, abrasive waterjet, ultrasonic, oxyflame, sawing and milling • Can be automated • 80% industrial lasers in Japan are used for metal cutting 7 This means that the beam for a fiber laser is roughly 100 times greater than that of a C02 equivalent when it comes to intensity. "}},{"@type":"Question","name":"What materials can be machine cut? The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 m… In flame cutting, oxygen is used as the assist gas. The process works by directing the laser beam through a nozzle to the workpiece. The gas in question is a carbon dioxide mixture which has been electrically stimulated. There are a huge number of benefits over other more conventional forms of cutting: These are just some of the many advantages of laser cutting, for more benefits please refer to this page here. There are also several techniques involved with the laser cutting process, which we have touched on briefly above: The main use for a laser machine, explained extensively in this article. The 'aluminium cutting system' which most modern equipment uses is actually a way of protecting the laser rather than an innovative technique for cutting. Melt Cutting. There are several laser machines now. The first step of the Laser cutting process begins with a request. Laser cutting is a precise method of cutting a design from a given material using a CAD file to guide it. As the name may suggest, this is the process of cutting a material using a laser beam. This effect can be reduced by adding a re-collimating optic, or some systems even use adaptive mirror control. Laser cutting is a slitting process with which metallic and non-metallic raw materials of different material thicknesses may be cut. Aluminium is more reflective than carbon manganese steel or stainless steel and has the potential to cause damage to the laser itself. The laser cutting process. A CO2 laser can cut thicker materials (>5mm) faster than a fibre laser of the same power. It all begins from the moment we receive an inquiry and continues through to the shipment of the manufactured parts. The lens is defined by its focal length, which is the distance from the lens to the focused spot. The Laser Cutting Process: Analysis and Applications presents a comprehensive understanding of the laser cutting process and its practical applications. Fibre laser sources have the following advantages: Direct diode laser technology is the latest progress in the field of solid-state lasers. We use CO 2 machines. These dents and holes are essentially cuts, and you’ll often see a cutting laser machine also being used for drilling and engraving too. Those used for material processing can generate beams of many kilowatts in power. In 1979, the Italian company Prima Industrie invented the first 3D laser-cutting process with a 5 axes rotation system. CO2 lasers typically emit at a wavelength of 10.6μm. Simply put, laser cutting is the process of using a laser to cut, score, engrave or otherwise alter physical materials. The only other consideration is that the shorter the focal length, the closer the lens is to the workpiece, and therefore more likely to get damaged by spatter from the cutting process. Direct diode lasers at multi-kilowatt levels of power are commercially available and have been successfully used for sheet metal cutting applications. This reflection does not come entirely from the sheet surface, but is caused by the formation of a molten pool which can be highly reflective. The gas in question is a carbon dioxide mixture which has been electrically stimulated. As the workpiece is not moved, this also means that there is no real limit to sheet weight. In remote cutting, the material is partially evaporated (ablated) by a high-intensity laser beam, allowing thin sheets to be cut with no assist gas.

Fibre lasers are a member of a family called ‘solid-state lasers’. Once the laser beam has completely penetrated the material at one point, the actual laser cutting process begins. We manufacture  both Pulsed Fiber and Continuous Wave (CW) Fiber Lasers to complete any cutting tasks. It also means that they can work with both metal and non-metal materials.\n\nA fiber laser is the most useful of the three types. For a constant focus length lens, increase in the raw beam diameter also reduces both the spot diameter and the depth of focus. The wall-plug efficiency of CO2 lasers is about 10%, which is higher than for most lamp-pumped solid-state lasers (eg ND:YAG lasers), but lower than for many diode-pumped lasers . This method uses nd:YAG (neodymium-doped yttrium aluminium garnet) and nd:YVO (neodymium-doped yttrium ortho-vanadate) lasers.
