Tapping chuck 636

Tapping chuck with minimum length compensation SYNCHRO T The feed axis is synchronised with spindle rotary movement on CNC machining centres. This means that threads with tool mounts without length compensation can be cut (“rigid tapping”) with these synchronised spindles. Practice, however, has shown that there are synchronisation faults. High axial forces reducing the service life by high flange friction develop as a result when rigid tapping chucks are being used leading to threads which are not true to gauge size or result in inaccurate threads. This problem is eliminated using tapping chucks with minimum length compensation.

SYNCHRO T tapping chucks technical features: • minimum length compensation on tension/compression (±0.5 mm) • high radial rigidity due to double bearing • high concentricity • high clamping force through clamping using collet chuck taps with female square • separate compression/tension mechanism • defined, adjustable compression/tension forces • compact, wear-free design • long service life • internal coolant supply • no clamping nuts with sealing discs necessary when using coolants, because the FAHRION tapping collets GERC-GBD are delivered with sealing plugs (usable up to 120 bar). • minimum quantity lubrication (MQL) possible upon request
