CBN Compact tools

CBN Compact tools are made of tungsten carbide substrate and the polycrystalline CBN composits sintered together into one piece. It shows remarkable performance in grinding as well as in profiling the complicated shape.

Features of CBN Compact tools

  • HRIt is most suited for grinding ferrous materials of above C50.
  • HRFerrous materials below C45 can be machined but in respect of economy it is not recommended.
  • High rate of material removal can be achieved hence improvement in grinding efficiency
  • High speed grinding can be carried out so it saves product cost.
  • When working temperature becomes high, chemical reaction isn't occurred so easily, so cutting edges cannot be blunt at short time.
  • High quality surface at high precision level can be achieve so it improves accuracy of machined workpiece.
  • If you use coolant, the tool life will be much improved.
  • The tool can be used after re-ground
