Abstract
The disclosed friction bit joining systems may include a ball screw having an internal bore, a chuck and spindle configured to be rotated by a chuck spindle motor, a friction bit joining bit held by the chuck, a support frame, and a chuck driver motor positioned and configure to rotate the ball screw to axially move the chuck and the friction bit joining bit relative to the support frame. At least a portion of the spindle may be positioned within the internal bore of the ball screw. Various other related systems and methods are also disclosed.
