Abstract
A hole-coldworking apparatus has a seamless sleeve and a mandrel which have complementary taper angles. The apparatus has a spindle assembly with a fixed section and a translating section. The fixed section is rotated by a motor and in turn rotates the translating section, the spindle, and the sleeve. The translating section is moved by an actuator to extend and retract the mandrel relative to the axially fixed section and the sleeve. The complementary tapers for the sleeve and mandrel radially expand a hole's diameter when the seamless sleeve is within the hole and the mandrel is retracted into the hole and presses against the seamless sleeve. When the mandrel is extended so that it is not in contact with the seamless sleeve, the mandrel and the seamless sleeve are rotated to assist in the insertion and the removal of the seamless sleeve in the hole.
