The laser cutting machine is a computer-controlled (CNC) machine that uses a powerful directional laser to cut various objects and materials. Many materials can be laser cut. From wood to leather and textiles, from acrylic, foam, and rubber. There are also various techniques, such as superimposition, engraving, halftone, and so on. This process can help you create amazing products, improve your marketing strategy, and grow your business. Or, if you only want to realize one of your ideas, laser cutting may be your choice. The process can be broken down into three main methods: CO2 and nbsp; laser (used for cutting, drilling and engraving), and neodymium (Nd) and neodymium yttrium-aluminum-garnet (Nd: YAG), which are identical in style, with Nd being used for high energy, low repetition boring and Nd: YAG used for very high-power boring and engraving. Using a CO2 laser, the current is passed through a gas mixture (excited by direct current), or more popular is the latest radio-frequency energy (RF excitation) technology.
How it works?
Laser cutting uses a powerful laser to direct a beam or material through optics and computer numerical control (CNC). This process uses a motion control system to track the CNC or G code of the pattern to be cut into the material. The focused laser beam melts, evaporates or is carried away by the gas jet and leaves a high-quality surface. The laser beam is generated by exciting the laser material with an electric current or a lamp in a closed container. The laser material is amplified by the internal reflection of the partial mirror until its energy is enough to leave a coherent monochromatic luminous flux. Use mirrors or optical fibers to focus the beam on the work area. These mirrors or optical fibers guide the beam through the magnifying glass. At the narrowest point, the laser beam is usually less than 0.0125 inches (0.32 mm) in diameter, but the cutting width is only 0.004 inches (0.10 mm) depends on the material thickness. If the laser cutting process must start from a point other than the edge of the material, use the perforation process, whereby a high power pulsed laser makes a hole in the material, for example taking 5-15 seconds to burn through a 0. 5-inch-thick (13 mm) stainless steel sheet. The RF method uses external electrodes to avoid problems related to electrode erosion and plating of the electrode materials in glassware and optics can be generated by direct current using electrodes in the cavity.
