Synchronous tapping chuck HSK according to DIN 69893-1 (DIN 69893-1)
For collet chucks type ER according to DIN 6499 ISO 15488
HSK HSK Form G 2,5
63 100 A 25000 rpm
Application: Execution:
For thread cutting on machine tools with synchro- ƒ Length compensation in compression and tension
nous spindles. With rigidly clamped screw taps, pitch 0.5 mm
errors cause high axial forces that can be compen-
sated for by synchronous tapping chucks through Advantage:
minimal length compensation under pressure and ƒ Pitch errors are compensated for under pressure
tension. ƒ Increased tool service life
