What is Fiber Laser Cutting? Definition, Process, Parameters & Types

Fiber laser cutting is revolutionizing the metal fabrication industry with its speed, precision, and efficiency. From automotive to aerospace, this advanced technology is shaping the future of manufacturing. In this guide by Hepta Engineering, we’ll explain the definition, process, key parameters, and types of fiber laser cutting—so you know why it’s a smart investment for modern industries.


What is Fiber Laser Cutting?

Fiber laser cutting is a thermal cutting process that uses a focused, high-powered laser beam to melt or vaporize material, usually metals, with extreme accuracy. The laser is generated through fiber optic cables, which offer better beam quality and energy efficiency than traditional CO₂ lasers.

At Hepta Engineering, we offer cutting-edge fiber laser cutting machines designed for optimal performance in industrial applications.


How Does the Fiber Laser Cutting Process Work?

The fiber laser cutting process involves several critical steps:

  1. Laser Generation: The fiber laser source produces a concentrated beam of light via diodes and fiber optics.

  2. Beam Delivery: The laser beam is transmitted through a lens system to the cutting head.

  3. Material Interaction: The beam focuses on the metal surface, heating it to the melting or vaporization point.

  4. Assist Gas: A stream of gas (often nitrogen or oxygen) blows away molten material, ensuring a clean cut.

  5. Motion System: CNC controllers guide the laser along the desired cutting path with micrometer precision.


Key Parameters of Fiber Laser Cutting

To achieve the best results, certain parameters must be optimized:

  • Laser Power (e.g., 1kW, 3kW, 6kW): Higher power enables faster cutting and thicker materials.

  • Cutting Speed: Must be adjusted based on material type and thickness.

  • Focus Position: Determines cut quality and kerf width.

  • Assist Gas Type and Pressure: Affects oxidation and edge smoothness.

  • Pulse Frequency (in pulsed mode): Crucial for materials like aluminum or copper.

At Hepta Engineering, our machines come with smart interfaces to easily adjust fiber laser cutting parameters for precise results.
