Abstract
A boring bar apparatus comprising a boring bar having at least one tool aperture formed therein. An axial translation mechanism for axially indexing the boring bar. The axial translation mechanism comprises a feed screw assembly having a threaded section, a rotational converter mechanism coupling the boring bar to the feed screw assembly for incrementally rotating the feed screw assembly, and a feed coupling having a first end engaging with the feed screw assembly and a second end engaging with the boring bar. The first end of the feed coupling having a threaded half nut section which, in a first position, engages with the feed screw assembly to facilitate axially indexing of the boring bar, and, in a second position, disengages from the feed screw assembly to facilitate moving both the feed coupling and the boring bar relative to the feed screw assembly to assist with repositioning of the boring bar.
