Cutting stainless steel with precision requires more than just a powerful fiber laser—it demands the right setup, settings, and techniques. In this comprehensive guide, we'll walk you through the essential steps to achieve flawless cuts using our SmartShop® Laser | CBX, as demonstrated by in-house expert Laser Dave.
Why Proper Fiber Laser Cutting Setup Matters
When working with stainless steel, efficiency and quality go hand-in-hand. A well-optimized cut condition ensures:
-
Minimal Gas Consumption: Reducing costs without compromising cut quality.
-
High Cutting Speeds: Maximizing productivity.
-
Clean Edges: Reducing post-processing time.
Step-by-Step Guide to Cutting Stainless Steel with a Fiber Laser
1. Setting Up Your Nitrogen Supply
-
Regulator Settings: Use a regulator capable of reaching up to 300 PSI. Start low and work your way up until you reach optimal results.
-
Why Nitrogen? Nitrogen prevents oxidation, ensuring clean, bright edges without discoloration.
2. Choosing the Right Nozzle
-
Single vs. Double Nozzle: For stainless steel, always opt for a single nozzle when using nitrogen. Double nozzles are better suited for carbon steel with oxygen.
-
Nozzle Swap: Ensure you've installed the correct nozzle before starting the cut. This one is important!
3. Configuring the Cut Condition
-
Speed Settings: Input an estimated cutting speed based on the material thickness.
-
Pro Tip: Start with a focal point near zero and adjust as needed after test cuts.
4. Performing Test Cuts
-
First Test: Observe the beam to ensure it isn’t "dancing" on the material.
-
Check for Slag/Dross: Minimal slag indicates good settings, but minor adjustments may be needed for perfection.
5. Optimizing for Perfection
-
Identify Issues: Slag often occurs during slowdown points in the cut path.
-
Fine-Tuning: Adjust the focal point slightly to eliminate imperfections.
Final Recommendations
After achieving a clean, slag-free cut:
-
Save Your Settings: This ensures consistency for future projects.
-
Replicate with Adjustments: For different stainless steel thicknesses, copy the cut condition and modify speed or focal settings as needed.
Common Mistakes to Avoid
-
Using the Wrong Nozzle: Double nozzles with nitrogen lead to subpar cuts.
-
Excessive Gas Pressure: Higher PSI doesn’t always mean better quality—optimize for efficiency.
-
Neglecting Focal Adjustments: Even slight changes can significantly improve cut quality.
