Product information "Tapping chucks for synchronisation SK40 - M3-M20 (ER25) - 84"

Application:
For machining centres with synchronous spindle.


Note:

  • Synchro tapping chucks compensate synchronisation errors.
  • Minimal length compensation on compression and expansion balances very small pitch differences between synchro spindle and tap, which can cause high frictional forces on the thread flanks.
  • A possible increase of axial force during the tapping process is reduced to a minimum.
  • Suitable for internal coolant.
  • Coolant pressure up to max. 100 bar.
