[CAD_CAM_EDM_DRO] Quilled

Hi all

Has anyone come across a good way to tighten up a quill on a drill/mill
style machine. While almost every article on CNC talks about backlash, few
mention the poor fit of quills. While I could use the built in clamp, it
only presses on two points, and has limited effect when the quill is fully
extended. Splitting the front of the head is not possible, it's a huge
piece of metal.

The only thing I've seen is to remove the quill and have it coated and
grind it to size. But there's no room for error there.. (no adjusting)

If only.... round columns were banished in the 80's, CNC conversions would
be a breeze..

Regards
Roland
