Description

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.

With balanced clamping nut


  • All holders are made of forged steel
  • Specific, low warpage hardened
  • Surface hardened HRC 58~60
  • Hardening depth 0,8mm~0,9mm
  • Taper angle tolerance < AT 3 according to DIN 2080
  • Surface roughness Ra < 0,4 µm
  • Tensile strength in the core of min. 800 N/mm² after DIN
  • All functional surfaces fine machined
