Description

Version:

Ground externally and internally. With Balluffchip bore.
Run-out and repetition accuracy 3 µm at 3×D, maximum 50 mm.
Very high clamping forces due to the collet fully seated in the chuck and coated clamping nut.
Vibration damping due to the element collet and mass of the chuck.
Alternatively without seals, with ER clamping nut CP No. 309655 or sealed system with ER clamping nut CP for HP sealing rings No. 309665 in conjunction with HP sealing rings No.309666 − 309668 (for internal coolant supply or as a dirt trap!).

Advantage:
