Drilling chuck and accessories

SYNCHRO T drilling chucks technical features: • minimum length compensation on tension/compression (±0.5 mm) • High radial rigidity due to double bearing • High concentricity • High clamping force due to clamping using collet chuck taps with female square • Separate compression/tension mechanism • Defined, adjustable compression/tension forces • Compact, wear-free design • Long life • Internal coolant supply • No clamping nuts with sealing discs necessary when using coolants, because the FAHRION drilling collets GERC-GBD are generally delivered with sealing plugs (usable up to 120 bar) • Minimum quantity lubrication (MQL) possible upon request

Drilling chuck with minimum length compensation SYNCHRO T The feed axis is synchronised with spindle rotary movement on CNC machining centres. This allows cutting threads without length compensation (“rigid drilling”) 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 drilling chucks are being used leading to threads which are not true to gauge size or result in inaccurate threads. This problem is eliminated using drilling chucks with minimum length compensation.

Design: With cylindrical shank according to DIN 1835 B+E. Supplied: Drilling chuck with clamping nut ST-GB. Note: Tightening occurs by means of roller spanner (Order No. 3657 on Ç 3/68). Suitable collets found on on Ç 3/92. Drilling chuck with minimum length compensation SYNCHRO T DIN 1835 B+E Form AD
