HSK System
FEATURES OF THE HSK SYSTEM
  • Suitable for high speed machining.
    When the taper hole is slightly seperated during high speed machining due to centrifugal force, the taper axis is continuously in contact with the taper hole because of elastic deformation.Thus, 2 face holding is maintained.
  • Guaranteed high accuracy.
    Installation repeatability of 2µis guaranteed.
  • High rigidity.
    High rigidity in the radial and thrust direction due to 2 face holding
    system.
  • Easy installation.
    Detachable support structure ensures separation of the tool even
    when the tool is under going thermal expansion.
  • Coolant system selection.
    Center coolant and anglar flow coolant type.
 HSK System: Main Features

*HSK stands for Hole (Hollow) Schaft (axis) Kegel (taper) in German.

HSK CLAMPING METHOD
HSK System Coupling Principles1
  • The 30° conical face of the taper axis is pulled in the direction of the tapered hole to clamp.
· Temporary Clamp Position

HSK System Coupling Principles2
  • Temporary clamp position has a clearance between the spindle and the tool contact faces.
  • Taper clamping force increases as the diameter increases.
·Permanent Clamp Position

HSK System Coupling Principles3
  • Hollow thin taper axis hold taper faces and the contact faces tightly due to pressurized elastic deformation.
