Epilog's high-speed CO2 laser machines come in a variety of configuations to fit your budget and application processing needs. Still, fabric is easy to cut, so a 60 watt or so should be able to handle it. BS EN 60825-1: 2014. The power of each laser can be changed according to the specific cutting requirements. High Power Metal Plate. Sheet metal cutting requires a power density of 10 6 watts/in 2 (source: Mike Klos @ laser mechanisms) Converting to millimeters, that's 1550 watts/mm 2. Professional Metal tube Coil Steel Laser Cutting Metal tube and plate. Typically, when upgrading to a new laser, the manufacturer will also recommend or require that you purchase a new dust collector. CO2 Lasers are among the most versatile of laser cutting and engraving machines capable of handling a number of different materials including wood, metal, glass, … Yes, there were some higher machine ratings available, but the most common were in this range. Chart #4 illustrates the characteristics for the four cutting lasers. Higher wattage lasers can etch or engrave more quickly, but the lower wattage UM-1 laser can perform the same markings with an extended cycle time. “Higherioved edge quality in the thicker range of materials like mild steel, aluminum and stainless steel,” Diehl explained. I cut quarter inch acrylic at 8 to 10mm/sec on 80 watts using a 65mm lens. Class 4 laser … This process is suitable for a wide range of materials, including metal, plastic, wood, gemstone, glass, and paper, and can produce … Buying Your First Laser Cutter. Now, higher-wattage systems paired with increasingly ri laser cutting process, said Dustin Diehl, laser division product manager for Amada America (Buena Park, CA). Safety of laser products: Part 1. are demonstration laser products subject to the requirements of 21 CFR 1040.11(c). The lens is defined by its focal length, which is the distance from the lens to the focused spot. The best way to determine your laser wattage requirements is to know the maximum thickness of material you need to cut through and the amount of product you need to engrave in a day. Plasma cutting is different. . Cutting things properly also involves matching the wavelength of the laser to the material to be cut; for most materials, this will be in the far IR range - not the near IR range, or UV range of most readily available and inexpensive laser diodes. Epilog Laser Safety of laser products - Part 14: A user’s guide. Fiber laser cutting heads designed for 1 to 4 kW cannot handle the energy density of the ultrahigh-power lasers. Productivity by design One major way is by dramatically boosting productivity. How can a Speedy laser engravers empower you? Laser cutting is a fabrication process which employs a focused, high-powered laser beam to cut material into custom shapes and designs. Its popularity has grown in recent years due to the degree of accuracy and complexity in cutting patterns, contours, designs, and shapes with precision. In this way, one machine can meet a variety of cutting requirements and achieve the effect of multi-purpose. Used in various industrial applications, this process can create permanent marks (laser marking), remove contaminants and coatings from surfaces (laser cleaning), modify a part’s roughness (laser texturing), cut through a surface (laser cutting) and much more. Laser cutting works by directing the output of a high-power laser most commonly through optics. Metal and Nonmetal. Let this overview of three different types guide you on your way. Laser ablation occurs when a laser beam removes material from a localized area. Any less will be painfully slow. The most common power levels ranged between 1,500 and 2,000 watts. However CO 2 lasers have not traditionally offered a good solution for cutting highly reflective materials. Laser engraving most materials can be accomplished with lower wattage and at a much faster rate than the thermal separation process needed for laser cutting of the same material. ↩ PD IEC TR 60825-14:2004. Flame cutting, also called reactive cutting, utilizes a laser beam coupled with oxygen gas or air to heat the substrate to its ignition temperature.While the heat produced by the laser beam melts the surface, the gas exothermically reacts with the substrate and creates an additional source of … In a plasma torch, volts and amps both count. Products Middle Metal Plate. Laser Source: CO2 laser, 30-120 watts; Work Area: 16" x 12" (406 x 305 mm) up to 40" x 28" (1016 x 711 mm) Max. Cutting a single layer of lightweight fabric should be easy at 20 watts. A CNC laser cutting machine cutting designs into a metal sheet. Most laser products are required by law to have a label listing the Class. Fiber lasers have an emission wavelength of around 1.07 µm, compared to 10.6 µm for traditional CO 2 alternatives. The high-power fibre laser presents a possibility for the application of solid-state lasers in thick-section metal cutting, a field which has been dominated by high-power CO 2 lasers. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. Things to be aware of are the mode quality, beam waste, spot size, and depth of field. For such large orders, if dies can be fashioned to reliably handle the required details of part geometries, there is usually little advantage to laser cutting systems because even the highest wattage modern systems are still a bit slower. In arc welding, whether stick, MIG, TIG, or whatever, it’s about amps — current. Laser cutting of mild steel and stainless steel has a long history and has been one of the primary applications for CO 2 lasers. When switching from CO2 to fiber laser cutting, or when upgrading to a higher wattage laser, it is important to evaluate your current dust collection system and determine whether it is up to the job. In this way, one machine can meet a variety of cutting requirements and achieve the effect of multi-purpose.
