Cutting Speeds Recomendations for Malleable cast iron - Ferritic

Application Vc (m/min) Vc (SFM)
Turning 320-485 1050-1590
Milling 215-325 710-1070
Parting 160-240 520-790
Grooving 225-335 740-1100
Drilling 180-275 590-900

Important! The speed estimation is given for an ideal situation:
  • Most suitable carbide grade
  • Stable tool clamping
  • Stable workpiece clamping
  • Good quality raw material
  • A short overhang of the cutting tool.
  • Nominal hardness of the material.
  • etc.
