WHERE THE CLAMPING DIAMETER IS
not concentric to the workpiece axis
s 4HE WORKPIECE IS CLAMPED COMPENSATING
s 4HE GRIP FORCE OF THE CHUCK SUPPLIES THE TORQUE NECESSARY TO MACHINE THE WORKPIECE
and pulls it down to the axial datum (center point/axial stop).
s $UE TO ITS HIGH RIGIDITY AGAINST TORSION THE CHUCK IS IDEAL FOR TURNING AS WELL AS FOR
milling operations
Technical features s PERMANENT GREASE LUBRICATION
s HIGH RIGIDITY AGAINST TORSION
s FOR OD CLAMPING ONLY s CENTER POINT ADJUSTABLE
s COMPENSATING CLAMPING WITH LARGE s prooine® chucks = fully sealed –
COMPENSATING STROKE LOW MAINTENANCE
s TONGUE GROOVE BASE JAWS
s PULL DOWN
Standard equipment Ordering example
3-jaw-chuck without centering insert Chuck FRC-N 215 A6
Mounting bolts
Non pull-down compensating chuck FRC-N pull-down and compensating clamping
Lifting of the top jaws pushes the shaft away from the center- The tailstock supplies the requested force to support the part
ing reference; high tailstock force has to be used to overcome only. The result is a cylindrical nished shaft with concentric
this lifting, resulting in a bending of the component diameters. The chuck pulls the work piece down to the center
point without bending the work piece
