Advanced Material Technology
UC5115 Grade (CVD Coating): This grade features a thick Al2O3 (Alumina) coating layer optimized for grey and ductile cast iron. It provides exceptional crater wear resistance and flank wear resistance at high speeds. The "Super" Toughness substrate ensures the tool remains stable during continuous cutting.
Standard Chipbreaker: Specifically designed for medium-to-finish turning, ensuring smooth chip evacuation even in short-chip materials like cast iron, preventing built-up edge and scratching.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron (FC) | 150 - 450 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Ductile Cast Iron (FCD) | 120 - 300 m/min | 0.10 - 0.20 mm/rev | 0.5 - 2.0 mm |

UC5115 is your primary choice for high-speed machining of cast iron. If you are machining steel instead, consider switching to UE6020. For stainless steel applications where toughness is required, US735 or VP15TF remain the superior options.
