How We Manufacture the Best Carbide Burrs
Step 1: Ultra-Fine Powder Blending
- High-purity tungsten carbide (WC) + cobalt (Co) mix
- Ensures perfect hardness & durability
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
Q: How do I choose between single-cut and double-cut?
Single Cut: Best for fine finishing (aluminum, plastics)
Double Cut: Best for aggressive material removal (steel, cast iron)
Q: What's the max RPM for these burrs?
- Steel: 25,000-35,000 RPM (use coolant)
- Hard alloys: Reduce speed by 20-30%
Q: Can I get custom shapes or sizes?
Yes! We specialize in custom geometries (MOQ 50pcs, 2-3 weeks lead time).
