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 2µm is guaranteed.

  • High rigidity.

High rigidity in the radial and thrust direction due to the 2 face holding system.

  • Easy installation.

Detachable support structure ensures separation of the tool even when the tool has undergone thermal expansion.

  • Coolant system selection.

Center coolant and anglar flow coolant type.

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

HSK Clamping Method

HSK System Form

There are various HSK types. Mitsubishi Materials produces A, B, C, and D types of taper axis (tool size) and C and D types (manual operation) of taper hole (spindle side).
