Fiber laser cutting machines, especially professional tube cutters, are born to deal with metal-stainless steel, carbon steel, aluminum alloy, brass, copper, galvanized pipes, and titanium alloy, to name a few. The absorption rate of metal in this band is extremely high, which brings high speed and high precision. Most of the current industrial systems are equipped with advanced back-reflection protection. Highly reflective materials such as brass and copper, which posed challenges for older laser technologies, can now be cut be cut easily without worrying about burning out the laser.
However, don't expect fiber lasers to cut wood, acrylic or cloth. These non-metallic materials have completely different absorption characteristics for light waves, which is the work of CO2 lasers. By focusing exclusively on metal processing, you can get narrower slits, a very small heat affected zone (HAZ), and photoelectric conversion efficiency of more than 30%-which directly means less electricity and faster return cycle.
Core Competency: Processing Basic Metals
Because the molecular structure of the metal absorbs this wavelength particularly well, the beam can melt or even gasify the metal extremely efficiently.
Stainless steel: the cut surface is very clean, with virtually no dross. For medical or food-grade equipment manufacturing, this is crucial.
Carbon steel and mild steel: This is the industry's workhorse. Fiber laser cutting low carbon steel speed is very fast, especially in the combination of oxygen as an auxiliary gas, the use of exothermic reaction can significantly improve cutting speeds.
Aluminum and aluminum alloy: Although the thermal conductivity of aluminum is very strong, but the fiber laser cutting common grades like 6061 or 7075 is straightforward, the accuracy of tube processing can also be maintained very well.
Galvanized pipes and titanium alloy: Whether it is for corrosion-resistant construction materials or demanding aerospace components, fiber lasers can provide sufficient processing stability.
Break Through The Bottleneck: Overcoming Highly Reflective Materials (Brass And Copper)
In the past, Highly reflective metals such as brass and copper were simply a "nightmare" for laser cutting ". Once the light path is reflected back into the laser, the damage is often catastrophic. Fortunately, the current fiber laser system has solved this problem, relying on advanced anti-high anti-protection technology. It can monitor the beam in real time and isolate the reflected light. Now, the processing workshop can safely accept these lists:
Copper: The material that must be used for electrical components and heat exchangers.
Brass: Used a lot in the decorative hardware and musical instrument industry.
Since there is no need to worry about burning out the resonant cavity, the processing service center has one more way to generate income.
Wavelength Limitations: Why Nonmetals Are Also "Banned"
Many people mistakely believe that "laser" can cut anything. But in the face of physics, this won't work. The wavelength characteristics of fiber laser determine that it will directly penetrate organic materials, or not be absorbed at all.
Wood and acrylic: These materials do not effectively absorb the 1.064 micron fiber wavelength. The laser can't cut it, or it can scorch the material directly, or even pass it directly without any response.
Textiles and plastics: Processing these materials requires longer wavelengths (usually 10.6 microns), which is the domain of CO2 lasers.
If you want to expand your business, this must be clear: fiber laser is a special tool for metal, and the field of non-metal is still the world of CO2 lasers.
The ROI Behind The Technical Advantages
In addition to what can be cut, how to cut is more important to the profit statement of the enterprise. Fiber laser technology has 3 obvious technical advantages that can help you get back to this faster:
Precision Cutting: For tube processing, the focused beam ensures complex shapes and bevels can be cut with extreme accuracy, which is vital for industries like automotive and furniture manufacturing.
Very small heat affected zone (HAZ): because of the fast cutting speed, the heat does not have time to spread to the surrounding, the cutting has been completed. This can effectively prevent the deformation of the workpiece and ensure the structural strength of the parts.
More than 30% photoelectric conversion efficiency: fiber laser is really power saving. Compared with CO2 lasers, which are usually only 8-10% efficient, fiber lasers can convert more than 30% of the electrical energy into actual laser power. This is directly reflected in the monthly electricity bill, the operating cost has been reduced, and the ROI period will naturally be faster.
