   CoA Constant face driver

For efficient high-precision turning of workpieces along their whole length without
rechucking. The modular principle design allows the unlimited exchange of driver
disks and centres.

One set consists of one basic body, one driving disc and suitable centre.

Technical features:
•  hydraulic pressure compensation provides a uniform clamping force also on
   uneven faces of workpieces
•  the spring loaded centre provides a longitudinal workpiece stop on the front side
•  clamping diameter 8-80 mm
•  workpiece weight max. 100 kg
•  approx. value for an axially admitted total load of 3 supporting pistons: 2000 daN
