6KW Fiber Laser Cutting Machine Application

A 6kW fiber laser cutting machine is a powerful tool commonly used for cutting various materials, including carbon steel. Here are some key points about using such a machine for carbon steel cutting:


  1. Precision and Speed: Fiber lasers provide high cutting precision and speed, making them ideal for intricate designs and high-volume production.
  2. Quality Cuts: They produce clean cuts with smooth edges, reducing the need for post-processing.
  3. Energy Efficiency: Fiber lasers are more energy-efficient compared to CO2 lasers.
  4. Low Maintenance: Fiber lasers typically require less maintenance and have a longer lifespan.

Cutting Parameters:

  • Power: 6kW is a high power level suitable for cutting thick carbon steel sheets.
  • Thickness: Depending on the specific machine and settings, a 6kW fiber laser can cut carbon steel up to approximately 25-30mm thick.
  • Speed: Cutting speed varies with material thickness. Thinner materials can be cut at higher speeds.


  1. Material Quality: The quality of the carbon steel can affect the cutting process and final quality.
  2. Assist Gas: The use of assist gases (such as oxygen or nitrogen) can influence cut quality and speed. Oxygen is often used for thicker materials, while nitrogen is used for cleaner cuts.
  3. Cooling and Ventilation: Proper cooling and ventilation are necessary to manage heat and fumes generated during cutting.


  • Protective Gear: Operators should wear appropriate safety gear, including eye protection, to guard against laser radiation.
  • Enclosure: Ensure the machine is properly enclosed to prevent accidental exposure to the laser beam.


Fiber laser cutting machines are used in various industries, including automotive, aerospace, manufacturing, and metal fabrication, for creating parts, components, and intricate designs.
