Tungsten Carbide Rods | The Core Material for High-Performance Milling Cutters
Core Advantages
✅ Ultra-Hard & Wear-Resistant: WC matrix hardness of HRA 90-93, offering 10x longer lifespan than high-speed steel.
✅ Precision Machinability: Blank rods support custom turning/grinding; precision-ground rods achieve tolerances of ±0.002mm.
✅ High-Temperature Stability: Maintains high strength at 1000°C, preventing edge softening caused by milling heat.
✅ Versatile Applications: Flat-end, ball-end, and tapered rods meet 2D/3D milling needs.

Industry Application Cases
Case 1: Aerospace Titanium Alloy Structural Parts
-
Challenge: Poor thermal conductivity of titanium alloys leads to chip adhesion and edge chipping.
-
Solution: YG10X precision-ground rods with TiSiN coating, used to manufacture Φ6mm wavy-edge milling cutters.
-
Result: Cutting speed increased by 30%, single-edge lifespan reached 120 minutes.
Case 2: Automotive Die-Casting Mold Repair
-
Challenge: High hardness of H13 mold steel (HRC 50) causes rapid wear of traditional cutters.
-
Solution: Custom step-type ball-end milling cutters made from YG8 blank rods, maintaining precision after 3 regrinds.
-
Result: Mold repair costs reduced by 45%.
