HSK DIN 69893 is the most common modern electrospindle connection, evolution of the classic SK connection. The most noticeable difference is the improved stability of the HSK, due to the “face-to-face” contact between the cone surface and the electrospindle nose. Thanks to this feature, HSK can safely reach speed levels impossible for SK, BT or CAT tool holders, while keeping high standard of precision and vibration control. With HSK tool holders run out stats are improved and spindle components lifespan is increased.
HSK Connection in its “A” shape configuration it is mostly used in high speed machines and is characterized by several cuts and notches to improve the spindle coupling.
