Fiber laser cutting machine compared with carbon dioxide laser cutting machine

What’s the difference between a fiber laser cutting machine and a CO₂ laser cutting machine?

When it comes to choosing the right laser cutting technology, understanding the differences between fiber and COâ‚‚ lasers is essential. One of the main distinctions lies in maintenance costs. COâ‚‚ laser cutting machines require regular and expensive maintenance. The front and rear mirrors are costly, and the turbine bearings typically last only 8,000 hours, with replacement costs reaching up to 80,000 yuan per set. In contrast, fiber laser cutting machines are virtually maintenance-free, with minimal consumables needed. They also perform well in harsh environments, showing strong resistance to dust, vibration, humidity, and temperature fluctuations.

Another key factor is processing cost. CO₂ laser cutting involves gas consumption and has a low photoelectric conversion efficiency, usually between 8% and 10%. On the other hand, fiber laser cutting machines don’t require any additional consumables during operation, and their photoelectric conversion rate can reach as high as 30%, making them more energy-efficient and cost-effective over time.

From a technical perspective, CO₂ lasers have a more complex structure, leading to higher maintenance costs. Their beam divergence is greater, which limits their effectiveness for large-format cutting. While they can produce thin cuts, they tend to be slower when working with thick materials. Fiber lasers, however, offer a compact design, high brightness, and excellent energy conversion rates. When it comes to thin plate cutting, fiber lasers can operate 2–3 times faster than CO₂ lasers, with cleaner and smoother cut edges.

Thanks to these advantages, fiber laser cutting machines have quickly gained popularity in the market, gradually replacing traditional cutting methods. Their reliability, efficiency, and performance make them an ideal choice for modern manufacturing, especially for applications that require precision and speed. Whether you're looking to reduce operational costs or improve production quality, fiber laser technology offers a compelling solution.
