Correctly Setting the Focus of Your 2000W Fiber Laser Metal Cutting Machine

Achieving optimal cutting results with a 2000W fiber laser machine requires careful consideration of the focus mode based on the workpiece material and thickness. When cutting the surface of a workpiece, the laser focus is crucial. For instance, when using air or nitrogen for cutting stainless steel, a negative focus is typically preferred. In this mode, the laser focuses below the cutting surface of the workpiece. This approach is particularly effective for cutting thick materials, as it allows for a larger cutting range and helps prevent oxygen-related issues that can impact cutting quality.

Alternatively, when cutting materials such as carbon steel, the focus is set differently. Here, the focus is generally on the cutting surface itself. This focus configuration ensures effective oxygen cutting and is suitable for materials like stainless steel or aluminum that require precise cutting parameters due to their higher hardness.

Choosing the correct focus mode is critical as it allows the laser cutting machine to leverage its performance advantages fully. By aligning the focus with the specific characteristics of the workpiece material and thickness, you can enhance cutting efficiency, minimize defects in the cut edges, and optimize the overall quality of the finished product.
