Expert Application Tips
For Optimal Performance:
- Use air-cooled die grinders (recommended 0.5-1.0MPa air pressure)
- Maintain 20-30° approach angle for best chip evacuation
- Apply aluminium-specific cutting fluid (water-soluble type preferred)
Troubleshooting Guide:
- Problem: Excessive burr wear
Solution: Reduce RPM by 20% and check workpiece hardness
- Problem: Material sticking
Solution: Increase feed rate or use specialized anti-galling burr
