MC5015 Grade & GK Breaker Detail
MC5015 CVD Coating: The MC5015 is a premium CVD coated carbide specifically optimized for grey cast iron turning. It utilizes a thick Al2O3 (Alumina) coating layer which acts as a thermal barrier, significantly reducing crater wear and flank wear during high-velocity production runs.
GK Chipbreaker: The GK geometry is a robust design for cast iron machining. It provides exceptional edge strength, ensuring that the tool resists the abrasive nature of cast iron chips while maintaining stable chip control and protecting the high surface finish of the component.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron (FC) | 200 - 550 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
| Ductile Cast Iron (FCD) | 150 - 350 m/min | 0.15 - 0.40 mm/rev | 1.0 - 3.5 mm |

MC5015 is your first choice for high-speed finish-to-medium turning of cast iron. If you are machining ductile iron under interrupted conditions, consider switching to MC5005 for increased wear resistance. For steel turning, the UE6110 or UE6020 grades are recommended to prevent premature failure.
