Some CNC programs offer “flying optics” capabilities that allow a laser to shape material while the cutting head is in motion. You can also see a video demonstration here: redENERGY G4 Pulsed Fiber Laser Cutting & Marking 0.3mm & 0.9mm Copper.\n\nCutting of aluminium foil\nAluminium foil is a metal that has uses for a range of industries, perhaps most commonly seen in the packaging industry. We would therefore recommend fiber lasers for your metal applications! In the beginning, the beam was directed through a lens via mirrors, but … All Rights Reserved. It is also more cost effective to pre-coat flat metal sheets prior to shipping them to a metal fabrication company rather than coating a metal part post fabrication. There are three types of cutting processes that you can use to cut metal with a laser; gas, crystal and fiber . However, metals like steel and ferrous materials are easier to cut than light or non-ferrous metals like copper or aluminum. We have written about the quick cut of thin aluminium foil here, where we found that the fastest speed was at 100kHz.\n\nIt is important that aluminium is cut using only one pulse, as it was found that repeated pulses could damage the metal.\n\nCutting of silver\nSilver is an extremely widely used metal, seen in both industrial and commercial settings for things such as jewellery, electronics, or energy devices. Projecting intense heat in an extremely narrow stream, laser cutting helps designers and welders to cut custom metal components and parts with the utmost accuracy. Mirrors or fiber optics are typically used to direct the coherent lightto a lens, which focuses the light at the work zone. This is known as flashback damage. Gas cutting is conducted with a carbon dioxide or nitrogen mixture, and crystal cutting, is conducted using nd:YAG (neodymium-doped yttrium aluminium garnet) and nd:YVO (neodymium-doped yttrium ortho-vanadate) crystals. Laser Cutting - nothing compares to the quality of a laser cut on many materials. Now that we have looked at the different processes and their effect on metal, we will now examine specific examples of the laser cutting of metal. There are three types of cutting processes that you can use to cut metal with a laser; gas, crystal and fiber . Laser cutting is an extremely valuable invention that has arisen from the past half-century. Can Your Company Help Provide Critical Supplies? Laser cutting leaves a high-quality surface finish and can be used with a variety of metals and materials. The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 m… You can read more on the making of Tower Bridge and the dragon here. You’ll commonly find this type of steel in a range of industries, such as the automotive and aerospace industries, and is key to forming the bodies and structures of the vehicle and aircraft. COVID-19 Response: Source manufacturers & distributors providing COVID-19 medical supplies The first table first table was machined … The list above is just a short list of the many different materials that can be processed by the CO2 lasers: there are lots of other materials that can be cut with the CO2 laser. This kind of modification uses the laser to preheat the steel while the oxygen catalyzes an exothermic reaction to assist in the cutting. COVID-19 Response Image credit: Guryanov Andrey/Shutterstock. Laser metal cutting can create many interesting shapes from metal, such as is shown in the image above, {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"Which type of laser should you use to cut metal? With a vast number of advantages, laser cutting has come to find itself used in numerous industries around the world, including the aerospace, automotive (including e-mobility),  semiconductor, electronics and medical industries.
