Fiber Laser Cutting: The High-Efficiency Tool Transforming Precision Machining

Laser cutting has long been an integral part of industrial production—from automotive parts to aerospace components—making material processing more precise and efficient. Among various laser cutting technologies, fiber laser cutting is rapidly replacing traditional CO₂ laser cutting with its outstanding advantages, emerging as a game-changer in precision machining.

 Compared to the well-established CO₂ laser cutting, fiber laser cutting offers distinct benefits. Technically, its wavelength is only 1064nm—one-tenth that of CO₂ lasers—meaning metals absorb it much more effectively. For instance, low-carbon steel absorbs 35% of fiber laser energy, while absorbing less than 10% of CO₂ laser energy. This allows fiber lasers to easily cut highly reflective materials like aluminum and copper, with superior beam quality and higher cutting precision.

In terms of efficiency, fiber laser cutting outperforms traditional methods by a wide margin. When cutting thin stainless steel sheets, it is 2 to 3 times faster than CO₂ laser cutting. A 2kW fiber laser cutting system can even slice through 0.5mm low-carbon steel at a speed of 40 meters per minute. For medium-thickness materials, it achieves the same cutting results with lower power, significantly boosting production efficiency.

The equipment itself also wins over businesses. Traditional CO₂ laser cutters are bulky and cumbersome, relying on mirrors for beam transmission, which limits large-format and multi-dimensional cutting. In contrast, fiber lasers transmit energy via optical fibers, featuring a compact design that saves space. They can flexibly cut arbitrary shapes, pipes, and special profiles—when integrated with industrial robots, they enable 3D cutting, adapting to diverse complex processing needs.

Cost advantages further drive its popularity. Fiber lasers boast an electro-optical conversion efficiency of up to 30%—more than three times that of CO₂ lasers—drastically reducing electricity consumption. Without complex light-guiding systems, their external optical paths are maintenance-free, with a mean time between failures (MTBF) exceeding 100,000 hours and virtually no consumables. This translates to substantial long-term savings in operational and maintenance costs for enterprises.

 Today, fiber laser cutting technology has matured significantly. Researchers have optimized process parameters to address thick-plate cutting quality issues and even achieved "striation-free cutting," drastically reducing surface roughness. Its applications in precision machining are expanding rapidly: it manufactures stainless steel vascular stents in the medical field, produces precision gears requiring 0.02mm accuracy, and meets the high-precision demands for thin-walled components in aerospace.
