Using a Self-Reversing Tapping Head on a CNC Mill

摘要

When I bought my manual mill/drill just a few years ago, all I wanted was a drill press with digital read-out (DRO). I was looking for the ability to both drill precisely positioned holes and also be able to return to the exact spot of a previous hole. The idea was to drill a set of holes the same size, then go back and tap them. Without the DRO, it would be drill-tap-move, drill-tap-move, constantly changing tools to ensure I didn't lose the hole position.
