How to Optimize Fiber Laser Settings for Maximum Cutting Thickness?


Optimizing fiber laser settings is crucial for achieving maximum cutting thickness across various materials. By adjusting specific parameters like focus and cutting speed, you can enhance the cutting capabilities of fiber laser cutters, allowing them to perform more efficiently and precisely.

  1. Laser Power Adjustment: Increasing the laser power is one of the most effective ways to enhance the cutting thickness. Higher power levels allow the laser to penetrate thicker materials such as carbon steel and stainless steel more effectively. For instance, increasing the laser power from 2 kW to 4 kW can significantly increase the maximum cutting thickness of stainless steel.
  2. Focus and Lens Quality: Proper focus settings ensure that the laser beam is concentrated at the optimal spot on the material’s surface. Using high-quality lenses can improve focus precision, resulting in better cutting performance. For example, precise focus adjustment is critical when cutting materials like alloy steel to avoid compromising surface cutting quality.
  3. Cutting Speed: Adjusting the cutting speed can also impact the thickness limit of materials that can be cut. Slower cutting speeds allow more time for the laser to penetrate thicker materials, improving cutting quality. A slower cutting speed can help achieve a clean cut on thick aluminum plates without leaving burrs.
  4. Use of Assist Gases: Using assist gases such as oxygen or nitrogen can enhance the cutting process. Oxygen can increase cutting speed and efficiency for metals like carbon steel, while nitrogen is preferred for stainless steel to achieve a clean cut edge.
  5. Nozzle Diameter: Selecting the appropriate nozzle diameter can influence the laser’s cutting ability. Smaller nozzles concentrate the laser beam more tightly, improving precision for detailed cuts. Adjusting the nozzle diameter can optimize cutting thickness when working with thin metal sheets.
