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
