What is Fiber laser Cutting?
Fiber laser cutting is a technology that applies a high-powered laser beam generated by a fiber laser to cut through an array of conductive materials such as aluminium, copper, stales steel, mild steel, titanium, gold etc. The laser beam is guided through a flexible optical fiber, which is then concentrated onto the workpiece via a lens. The focused beam generated by the diodes melts or vaporizes the material, allowing the laser to pierce through the different conductive materials.
Fiber laser cutting has an few advantages over other technologies such as plasma cutting (depending on material and thickness) and also compared to older laser cutting technologies such as CO2.
One of its´ advantages are the faster cutting speeds and the greater edge quality in thinner material. Fiberlasers have a higher power density and are able to cut through materials at a rapid rate and with a greater level of precision than plasma cutting.
Other good points in favour of fiberlaser cutting is the high beam quality. Fiber lasers have a far superior beam quality compared to CO2 lasers, which allows them to cut through thin and thicker materials.
The operating costs of fiberlaser cutting machines are far less when compared to CO2 lasers. Operating costs of fiber lasers are more efficient due to that they are up to 80% more energy efficient. This results in lowered operating cost and lead to higher profit margins.
The low maintenance costs on a Fiber laser, also speak hugely in favour of this technology, as there are less consumables and moving parts, unlike CO2 lasers which need the replacement of mirrors and lenses periodically.
The versatility of the Fiber laser cutting machine allows for its´ use in a very broad range of industries, including the aerospace, automotive, medical equipment, and electronics industries.
This technology is also frequently used in metal fabrication, sheet metal processing, and prototyping industries. With the capacity to cut a far-reaching range of metal thicknesses and types, fiber laser cutting is developing into a more popular option as it allows for more considerable flexibility and efficiency in the manufacturing process.
Fiber laser cutting does however have some limitation like not being suitable for transparent materials, or having poor cut quality in reflective materials, it also has a limited depth of cut in thicker metal parts. It’s important to carefully evaluate your manufacturing needs and the suitability of the technology for a given material or thickness that you might use. Before committing to purchasing a fiberlaser cutting machine, the above considerations should be taken into consideration.
Here are two examples of industries showing how the fiberlaser is effective in these specific sectors.
