Technical Information:

• Cast iron is a Fe-C alloy with a high Si content (1-3%). The carbon content exceeds 2%. Cr, Mo, V, etc. form a hardened material, which increases the strength and hardness of the material, but reduces the machinability.
• Contrary to steel, cast iron is a short chip material with good chip control under most operating conditions.
• Cast iron can be divided into malleable cast iron (MCI), grey cast iron (GCI), ductile iron (NCI), compacted graphite iron (CGI), austenitic ductile iron (ADI).
  • Gray cast iron and malleable cast iron are very easy to process.
    • Ductile iron, vermicular cast iron and austenitic cast iron are more difficult to machine. All SiC-containing cast irons cause significant abrasive wear on the cutting edges.
  • Gray cast iron and ductile iron, GCI & NCI:
    • Material classification: K2.x and K3.x
    • Gray cast iron and nodular cast iron are the most common types of cast iron.
    • Gray cast iron features low impact strength, good thermal conductivity and good vibration damping.
    • Ductile iron has good stiffness, good toughness, good tensile strength and poor thermal conductivity.
  • Malleable cast iron, MCI:
    • Material classification: K1.x
    • Malleable cast iron is less sensitive to cracks and has higher fracture strength and elongation.
  • Vermicular graphite cast iron, CGI:
    • Material classification: K4.x
    • Vermicular graphite cast iron can meet the ever-increasing requirements for increased strength and weight, but still maintains reasonable cutting performance.
    • Vermicular cast iron has twice the fatigue resistance of grey cast iron.
  • Austenitic ductile iron, ADI:
    • Material classification: K5.x
    • Austenitic ductile iron is a unique series of cast irons obtained by heat treatment.
    • Austenitic ductile iron has excellent strength, toughness and fatigue resistance.

Recommended Cutting Parameters:

• The following cutting parameters are the recommended range values. Appropriate adjustments and selections should be considered after considering the following factors:
  • Specific physical properties of the material being processed
  • The actual condition of the part blank
  • Power and rigidity of the machine tool
  • Clamping rigidity of tools and workpieces
  • Balance between tool life and machining efficiency
