What is a Fiber Laser Cutting Machine?
A fiber laser cutting machine is an advanced CNC cutting system that utilizes a high-powered fiber laser to cut metals and other materials with extreme precision. Unlike CO2 lasers, fiber lasers use a fiber-optic cable to generate and deliver the laser beam, making them more efficient and durable.
How Does a Fiber Laser Cutter Work?
- Laser Source Generation – The laser beam is produced using a fiber laser resonator.
- Beam Transmission – The beam travels through an optical fiber cable, ensuring minimal energy loss.
- Focusing Optics – A lens focuses the laser onto the material surface, creating an intense heat zone.
- Material Melting & Evaporation – The laser melts and vaporizes the metal, following the programmed design.
- Assist Gas Ejection – High-pressure gas (Oxygen, Nitrogen, or Air) removes molten material, ensuring a clean cut.
Key Features of Fiber Laser Cutting Machines
✅ High Cutting Speed – 2-3 times faster than CO2 laser cutters.
✅ Superior Precision – Capable of cutting with tolerances as low as ±0.02mm.
✅ Low Maintenance – No mirrors or moving parts in the laser source, reducing upkeep costs.
