Hollow taper shank DIN 69893 HSK-A, HSK-E, HSK-F

Products hollow taper shank DIN 69893 HSK-A, HSK-E, HSK-F, Tool Holder & Tool Clamping technology by HAIMER

The interface DIN 69893 has become the new standard for machining centres. The holder is clamped via its taper with flange contact surface. By doing so, a highly accurate centring and fixed axial position of the holder in the spindle is granted with a high repetitive accuracy when exchanging the tools. In the DIN 69893-1 HSK-A interface design an additional torque transmission takes place at the taper shank with drive keys. DIN 69893 HSK-A/HSK-E/HSK-F is mainly used in high-speed machining.
