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
