The process of using an oxy-fuel cutting stream dates back to 1907. It is most accurately described as rapid controlled rusting, used for purpose of metal breakdown. Oxy-fuel itself is a chemical reaction between pure oxygen and steel to form iron oxide. Oxy-fuel cutting works by using preheat flames to raise the surface or edge of a metal, for example steel, to approximately 1800°F . Pure oxygen is then directed toward the heated area in a fine, high pressure stream. The steel is rapidly oxidised and is blown away from the cutting area, which leaves a cavity. The preheat and oxygen stream are moved at consistent pace to form a continuous cut. Only certain metals can be cut with the oxy-fuel...
Lasers are used in many different ways, one of which is cutting intricate shapes from metal plate. When a laser cutter is used to cut a metal plate, the laser cutting head must be adjusted accordingly. In order to cut specific shapes, the cutting head must be positioned above the plate, then moved over the shape of the desired part, cutting that part out of the plate. To assist in this process, a capacitive height control system can be used. This works by maintaining very accurate distance between the end of the nozzle and the plate that is being cut. This distance is important, because it determines where the focal point is relative to the surface...
Lasers are used for many purposes in industry. A common way they are utilised, especially in manufacturing, is for cutting. For a laser beam to cut through metal it must be focused so that it is powerful enough to do so. This is achieved using special lens, or by a curved mirror, and this takes place in the laser cutting head. The beam is precisely focused so that the shape of the focus spot and the density of the energy in that spot are perfectly round and consistent Laser cutting is used to cut materials such as mild steel, stainless steel, and aluminum plate. It yields excellent an excellent trim quality and also has a very small...
Laser cutting is a highly specialised manufacturing process. It requires specialised equipment which is often expensive, as well as knowledge of lasers and technical knowledge. This post looks at the way lasers work to carry out their function. A laser beam is composed of a column of very high intensity light, consisting of a single wavelength or colour. 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 around 3/4 of an inch in diameter. It travels from the laser resonator, which creates the beam, through the machine’s beam path. After...
Lasers are perfect for making precision cuts, and no less so on paper and cardboard products. Being particularly suited for cutting fine geometries with maximum precision and quality, Laser paper cutting allow for cutting even the most delicate paper constructions, and creating a professional and clean, finished product. Its important to note that when cutting paper with lasers, the paper can sometimes burn. Just like wood, which has a similar chemical composition, paper is evaporated suddenly. This is called sublimation. In the area of the cutting clearance, the paper escapes in gaseous form, which is visible in the form smoke (at a high rate). This smoke transports the heat away from the paper, meaning...
