Unique CO2 Laser Cutting ProcessesApril 7, 2023
Laser can be used to cut a wide variety of materials. With a laser cutting machine, paper and plastic can be easily cut much precisely. Even plywood up to 1″ thick can be cut by this machine. It can be used to cut metal sheets as well. Typically power of the laser is modulated to select various levels cutting.
Small mirrors are used to guide light from the Fiber Laser Parts Manufacturer to a particular location on the material. The base of the cutting area is made from a honeycomb material to let the laser light pass through. This has to be replaced periodically.
Laser cutting machines are distinct from traditional mechanical cutters. Since the laser never makes physical contact with material and there is less opportunity for the material to become contaminated. Laser cutting machines also cut material with higher precision than that of mechanical means.Besides its advantages over conventional mechanical cutting, laser cutting is a quiet process. Safety is also important and, as a result, most laser machines are fully enclosed to prevent accidents.
The most common type of laser cutter available in industry today is the CO2 laser. It offers advantages over other types of lasers for cutting in cost, efficiency and power available and have become the industry standard.
Laser cutting with a CO2 lasers finish is excellent in comparison to processes such as oxy or plasma. Correct use of efficient nozzles, feed speeds, pulse settings and gas pressures can produce good square cuts with a smooth finish. For most applications only minimal post finishing is required. However, CO2 laser cutting cannot replicate a machined finish. Parts typically have a heat affected zone, but this is small in comparison to the more traditional processes. Heat distortion is very minimal and this is one of the key advantages of the process.
CO2 laser system can be used almost anywhere the more conventional processes such as oxy and plasma cutting are used. But, a CO2 laser cutter has the advantage in being able to cut a wider variety of materials such as plastics and wood. CO2 lasers can be mounted on various different motion systems from small desktop units for small work, to huge gantry systems for cutting large plates, to robot arms for 3D cutting.
Just a few of the wide variety of applications for CO2 laser cutting are profiling of steel shapes, cutting or drilling of holes in steel parts, cutting of thin sheet metals, cutting of plastic signs and masks, cutting of profiles in wood and cutting of fabrics and plastic films.
