Step 2: Cold Isostatic Pressing (CIP)
  • Compressed at 300+ MPa for void-free density
Step 3: Precision Sintering
  • Heated to 1420°C in vacuum furnaces
  • Achieves maximum carbide hardness
Step 4: 5-Axis CNC Grinding
  • ±0.005mm tolerance for perfect balance
  • Mirror-finish flutes for smoother cuts
Step 5: 100% Quality Control
  • Hardness testing
  • Dimensional accuracy check
  • Visual inspection

Every burr meets ISO 9001 standards

Frequently Asked Questions
