Introduction
Series 646 Hydraulic Collet Grips Force and Torque Capacities
The amount of torque the grips can produce is reduced with biaxial operation.
The amount of torque is affected by the amount of axial force and the size of the
specimen. The following graphs illustrate the axial-torsional performance
envelope of the Model 646.10 and Model 646.25 Hydraulic Collet Grips.
