Grade & Chipbreaker Technology
UC5115 Grade (CVD Coated): Specifically optimized for cast iron. This grade features a thick Alumina (Al2O3) coating that provides extreme crater wear resistance and thermal stability. It allows for higher cutting speeds compared to conventional grades, significantly reducing cycle times.
Standard Chipbreaker: Optimized for medium-range cutting, ensuring smooth chip evacuation and preventing built-up edge, even in dusty cast iron machining environments.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron | 150 - 450 m/min | 0.15 - 0.40 mm/rev | 0.5 - 3.0 mm |
| Ductile Cast Iron | 120 - 300 m/min | 0.15 - 0.35 mm/rev | 0.5 - 2.5 mm |
