Fiber lasers are solid-state lasers used widely in laser marking and engraving machines. The major difference between a fiber laser and a CO2 laser lies in their ability to laser cut sheet metal.
You can reach them by phone, email, or via their social media accounts for after-sales support.
A special type of fiber laser known as MOPA fiber laser, provides greater control over pulse width and frequency parameters to produce color laser engravings on metals.
Gulf States Saw & Machine Co. supplies an EZCAD2.0 Laser Control Software with the Gulf States Saw & Machine Co.’s FM1212-50S Laser Engraver Machine.
Using a Raycus 50W fiber laser, you can engrave in stainless steel at a 90° angle with a speed of ~3,540 ipm by utilizing 100% of the laser power.
The support column (Z axis) holds and controls the laser arm. You can adjust the laser focus by moving the Z axis using the height adjustment knob.
It can be used for flatbed cutting and bevel cutting, and the edges are neat and smooth. It is suitable for precision cutting of sheet metals. In addition, the robotic arm can do 3D cutting instead of the 5 axis laser cutter. Compared with CO2 laser cutters, fiber laser cutters will save space and gas consumption, and has a high photoelectric conversion rate. It is a new power tool of energy saving and environmental protection, and it is also one of the world's leading technological CNC machine tools. 1. High accuracy: The laser positioning accuracy is 0.05mm, and the repeated positioning accuracy is 0.03mm, 2. Narrow slit: The laser beam is focused into a small spot, so that the focus reaches a high power density, the material is rapidly heated to the point of vaporization, and the holes are vaporized. With the relative linear motion of the light beam and the material, the hole continuously forms a narrow slit, and the width of the slit is generally 0.10-0.20mm, 3. Smooth cutting edge: There is no burr on the cutting edge, and the roughness of the cutting surface is generally controlled within Ra6.5., 4. High speed: The cutting speed can reach 10m/min, and the maximum positioning speed can reach 30m/min, which is much faster than other metal cutting tools., 5. High quality: It is a non-contact cutting, which endures little thermal influence, the part basically has no thermal deformation, and completely avoids the slump formed when the material is punched and sheared., 6. Non-destructive cutting: The laser cutting head does not come into contact with the surface of the substrate, ensuring that the parts are not scratched., 7. Good flexibility: Laser has good flexibility to cut any graphics, including metal pipes and other shaped metals, 8. Save mold investment: Laser cutting requires no mold, no mold consumption, no mold repair, saving mold replacement time, thereby saving processing costs and reducing production costs, especially suitable for processing large projects, 9. Material saving: With CNC programming, the parts of different shapes can be cut to maximize the utilization rate of materials., 10. Easy to use: Using CAD software to design graphics, using CAM software to model and output laser cutting files, using CNC controller to drive the machine to achieve automatic metal cutting, 11. Safety and environmental protection: Less waste, low noise, clean, safe and pollution-free, greatly improving the working environment.
They can import different file formats including DXF, BMP, DXF or AI.
However, fiber lasers can be very expensive and you may need a laser engraver that is affordable.
Fiber lasers are very popular in engraving applications. They have wavelengths ranging from 780nm up to 2200nm.
MCWlaser PRO is available in half-assembled form. First, fix the vertical column linking the laser source to the laser engraving modules.
A low cost fiber laser sheet metal cutter is priced from $16,000, while some high power sheet metal cutters cost up to $300,000+. A fiber laser tube cutter has a price range from $45,500 to $117,500 for all types of pipe cuts. An all-in-one fiber laser sheet metal and tube cutting machines is priced from $42,500 to $236,800. An automtic industrial 3D fiber laser cutting robot will cost from $49,000 to $83,500 for multi-dimensional & multi-angle metal cuts.
FSL Muse Pandora features a mirror gallvanometer in the laser head that tracks the laser's path before it cuts and gives a rough idea about the cuts it will make.
The laser beam is then amplified using an optical fiber and fed to a cutting head.
What Materials Can Be Cut With A Fiber Laser? A fiber laser cutting machine can cut sheet metal such as carbon steel, stainless steel, copper, brass, aluminum, and titanium. Fiber lasers outperform CO2 lasers in cutting reflective materials.
The wavelength is the primary distinction that determines the types of materials that each laser can process. The wavelength of a fiber laser is typically 1,060 nm, whereas CO2 lasers have wavelengths in the 10,600 nm range. Fiber lasers have many advantages over CO2 lasers in general.
Fiber lasers typically cost between $20,000 and $45,000.
