Fiber laser cutting machine for metal sheets typically refer to two-dimensional laser cutting systems used for processing flat metal materials. They utilize a fiber laser to output high-energy-density laser light, which is focused by the cutting head and applied to the surface of the sheet metal. Melting, vaporization, or oxidation reactions are completed in a very short time, and the molten metal is blown away from the kerf with the help of auxiliary gas, thus creating a high-precision cut.
For modern sheet metal, chassis and cabinet, construction machinery, automotive parts, hardware products, and steel structure industries, this type of equipment has become essential for high-efficiency, high-flexibility, and low-contact processing. The core advantages of fiber laser technology lie in its high efficiency, low energy consumption, strong integration, and the ability to achieve good speed and edge quality when cutting metal.
A fiber laser cutting machine for metal sheets is an advanced CNC machining equipment that uses a high-energy-density fiber laser beam to melt and vaporize metal materials, and then uses assist gas to achieve high-speed cutting.

It has become one of the most crucial pieces of equipment in the modern metal processing industry.
The fiber laser generates a high-quality laser beam through:
- Semiconductor pump source
- Rare-earth element-doped fiber
- Resonant cavity system
This laser beam passes through:
- Fiber transmission
- Collimation

Ultimately forming a spot of extremely high energy density.
The spot temperature can instantly reach:
- Thousands of degrees Celsius
- Even tens of thousands of degrees Celsius
This causes the metal to rapidly:
- Melt
