1. Ultimate Beam Quality – The Physical Basis of "Fast, Precise, and Powerful" Cutting
This is the core source of the power of fiber lasers. Lasers are generated and transmitted within flexible optical fibers, inherently possessing extremely high beam quality.
Extremely High Energy Density: It can concentrate enormous energy into an extremely small point, achieving an energy density more than 100 times that of ordinary CO2 lasers. This means it can vaporize materials instantaneously (in milliseconds), achieving "non-contact" cutting.
High Cutting Speed: For thin sheet metals (such as 1mm stainless steel), its cutting speed can reach tens of meters per minute, far exceeding traditional CO2 lasers and plasma cutting.
Narrow Kerf and High Precision: The extremely small focused spot allows for kerfs thinner than a human hair, resulting in highly precise part contours with virtually no thermal deformation, achieving "precision cutting."
2. Unparalleled Cutting Efficiency – "Time is Money"
In industrial production, efficiency directly determines profitability.
Extremely High Processing Speed: As mentioned above, when cutting thin plates, its speed is several times, even tens of times, faster than traditional methods.
Extremely Short Start-up Time: Fiber lasers have "zero start-up time"; light is emitted instantly upon pressing the switch, unlike CO2 lasers which require preheating gas. Simultaneously, its piercing speed during the cutting process is also extremely fast.
Integrated Automation: Easily integrated with robotic arms and automated loading and unloading systems, enabling 24/7 uninterrupted production and creating a "lights-out factory."
3. Wide Material Adaptability – "Multi-purpose"
Fiber lasers (wavelength 1.06μm) are particularly adept at cutting metal materials, which is their primary application.
Low Reflectivity Advantage: Compared to CO2 lasers (wavelength 10.6μm), fiber lasers have a shorter wavelength, resulting in higher absorption rates by metal materials. This makes them more efficient and stable when cutting highly reflective metals such as copper, brass, and aluminum, and less prone to equipment damage from reflected light.
List of Cuttable Materials:
Carbon Steel: Performs exceptionally well, especially on thin and medium-thick plates, producing smooth, slag-free cuts.
Stainless Steel: Produces bright, aesthetically pleasing cuts with minimal oxidation.
Aluminum/Copper Alloys: While more difficult to cut than the previous two, fiber lasers are currently one of the most effective tools.
Other Metals: Also suitable for cutting materials such as titanium alloys and galvanized sheets.
Note: It is not effective at cutting non-metallic materials (such as wood, acrylic, and stone) due to wavelength mismatch and extremely low absorption.
4. Significant Economic Benefits – “Low Overall Cost”
Although initial investment may be higher, its long-term operating costs are highly competitive.
Extremely High Photoelectric Conversion Efficiency: Fiber lasers achieve an electro-optical conversion efficiency of 30%-50%, while traditional CO2 lasers typically only reach 10%-15%. This means that to produce the same laser power, fiber lasers consume less power, resulting in substantial long-term electricity savings.
Extremely low maintenance costs: The entire optical path is integrated inside the fiber, eliminating the need for path adjustments and eliminating the need for consumables like mirrors, lenses, and gases that require periodic replacement, as is common with CO2 lasers. Routine maintenance primarily involves cleaning and protecting the lenses, significantly reducing maintenance workload and costs.
Low operating costs: No laser gases (such as CO2, N₂, He) are required; only electricity is needed.
5. Superior processing quality – “Guaranteed Quality” High-quality cut surfaces: Smooth cut surfaces with high perpendicularity and minimal or no slag buildup, often allowing for direct welding and eliminating secondary processing steps.
Small heat-affected zone: Due to the high speed and concentrated heat, very little excess heat is transferred to the material, resulting in minimal deformation and excellent preservation of the material's original properties.
