The result is a cylindrical finished shaft with concentric diameters. The chuck pulls the workpiece down to the center point without bending the workpiece. ■ Non pull-down compensating chuck Lifting of the top jaws pushes the shaft away from the centering reference; high tailstock force has to be used to overcome this lifting, resulting in a bending of the component. Technical data Application/customer benefits • Compensating clamping of shafts between centers, where the clamping diameter is not concentric to the workpiece axis • The 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) • Due to its high rigidity against torsion the chuck is ideal for turning as well as for milling operations Technical features • For O.D. clamping only • Compensating clamping with large compensating stroke • TONGUE & GROOVE base jaws • Pull down to axial datum • Centrifugal force compensation • Permanent grease lubrication • High rigidity against torsion • Center point adjustable • proofline® chucks = fully sealed - low maintenance Standard equipment Ordering example 3-jaw chuck without centering insert Mounting bolts Lever chuck FRC-N 215 A6 SMW-AUTOBLOK Type Angular jaw stroke U° deg.
