Abstract
A machine, which is portable, and method for roller swaging hydraulic fitting sleeves onto metallic tubing comprises a tapered roller mandrel expander under either or both torque control of swaging or diameter control of swaging. The machine provides an automatic swaging cycle with an optimum overall time cycle for swaging performance. A motor drive is movably mounted relative to the mandrel expander assembly. The motor drive is manually moved longitudinally to activate the mandrel. Portability and hand held use can be effected by removing the power unit from the frame.
