UC5115 Grade Material
The UC5115 grade is Mitsubishi's premier choice for Cast Iron turning. By utilizing a thick CVD coating with optimized Alumina ($Al_2O_3$) layers, it achieves extreme hardness. This indexable turning insert is designed to withstand the abrasive nature of grey and ductile iron while maintaining a sharp edge.
MA Chipbreaker Geometry
The MA chipbreaker is a balanced medium-cutting geometry. Even in brittle materials like cast iron, it provides a stable cutting action that reduces vibration and improves surface finish. It prevents chip welding and facilitates high-speed machining without compromising tool integrity.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Grey Cast Iron (FC250) | 200 - 450 m/min | 0.15 - 0.45 mm/rev | 0.5 - 4.0 mm |
| Ductile Cast Iron (FCD) | 150 - 350 m/min | 0.15 - 0.40 mm/rev | 0.5 - 3.5 mm |
