Air Compressor Using in Fiber Laser Cleaning/Rust Removal Machine
Using an air compressor in a fiber laser cleaning/rust removal machine is essential for assisting the laser ablation process, removing debris, and cooling the workpiece. Here’s a detailed breakdown of its role, requirements, and best practices:
1. Role of the Air Compressor in Fiber Laser Cleaning
Blowing Away Debris: The compressed air jet helps remove loosened rust, paint, or contaminants from the surface during laser ablation.
Cooling the Surface: Prevents excessive heat buildup, which could damage the substrate.
Enhancing Laser Efficiency: Clean, dry air ensures optimal laser performance by preventing smoke or particles from interfering with the beam.
Protecting Optics: Prevents debris from depositing on the laser lens or mirrors.
2. Key Requirements for the Air Compressor
| Parameter | Requirement |
|---|---|
| Pressure | 4–8 bar (60–120 psi) |
| Flow Rate | 100–300 L/min (depends on nozzle size & laser power) |
| Air Quality | Oil-free, dry air (ISO 8573-1 Class 1 or 2) |
| Tank Capacity | 50–100L (for stable pressure) |
| Noise Level | <75 dB (if used in indoor/sensitive environments) |
⚠️ Critical:
Oil-free compressors are mandatory—oil vapor can contaminate the workpiece and damage laser optics.
A refrigerated or desiccant air dryer is recommended to prevent moisture buildup.
3. Setup & Best Practices
A. Air Delivery System
Use stainless steel or PTFE air hoses (resistant to corrosion and particle buildup).
Install an inline filter (0.01 µm) to remove residual moisture and particles.
Position the nozzle at 30–60° angle, 5–20 mm from the surface (adjust based on material).
B. Laser Compatibility
Some fiber laser systems integrate automated air pressure control—match the compressor’s output to the laser’s requirements.
Higher-power lasers (e.g., 500W+) may need higher airflow to manage debris effectively.
C. Maintenance
Drain the compressor tank daily to prevent moisture accumulation.
Replace filters every 3–6 months (or as per manufacturer guidelines).
Check for air leaks regularly to maintain consistent pressure.
4. Recommended Compressor Types
Oil-Free Piston Compressor (for small-scale/low-duty applications).
Oil-Free Scroll Compressor (quieter, better for continuous operation).
Screw Compressor (best for industrial/high-duty cycles).
5. Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Weak debris removal | Low pressure/flow | Increase pressure, check for leaks |
| Moisture on workpiece | Wet air supply | Install a dryer, drain tank |
| Laser lens contamination | Dirty air/no oil filter | Upgrade filtration, use oil-free compressor |
