Fiber laser cutting machine compared with carbon dioxide laser cutting machine

What is the difference between a fiber laser cutting machine and a carbon dioxide (COâ‚‚) laser cutting machine?

When it comes to choosing between a fiber laser cutting machine and a COâ‚‚ laser cutting machine, there are several key factors to consider. One of the most significant differences 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 around 8,000 hours, with each replacement costing up to 80,000 yuan. In contrast, fiber laser cutting machines are virtually maintenance-free, with minimal consumables and excellent performance in harsh environments, making them more durable and reliable.

Another major difference is the processing cost. COâ‚‚ laser cutting machines not only consume gas but also have a low photoelectric conversion efficiency, usually between 8% and 10%. This makes them less energy-efficient. On the other hand, fiber laser cutting machines do not require any additional consumables during operation and offer a much higher photoelectric conversion rate of up to 30%, making them more energy-efficient and cost-effective over time.

From a technical standpoint, CO₂ laser cutting machines have a more complex structure, leading to higher maintenance costs and limitations in large-format applications due to beam divergence. While they can produce thin cuts, they tend to be slower when working with thick materials. Fiber laser cutting machines, however, are compact, efficient, and feature high brightness and a high conversion rate. They offer significantly faster cutting speeds—up to two to three times faster than CO₂ lasers for thin plates—while delivering smoother cut surfaces.

The growing popularity of fiber laser cutting machines in the market can be attributed to their numerous technical advantages. These machines provide a more efficient and precise process, making them ideal for modern manufacturing needs. As industries continue to evolve, fiber lasers are increasingly becoming the preferred choice for cutting and shaping materials in a wide range of applications.
