I understand the principle of using a universal dividing head
in order to mill helixes (eg. helical gear teeth, spiral flutes)
and basically how they are set up; they are driven by the table's
feed mechanism to provide simultaneous linear and rotational motion
to the work at a given ratio.
From what I've read, most milling machines have optional accessory
dividing heads whose drive input is designed for that machine's
specific feed mechanism. I have a Hardinge TM (plain non-swiveling
table) milling machine with no power feed. I know that Hardinge made
a dividing head for the TM and UM millers that have power feed.
WAY too expensive and hard to find for my budget. I see also that
there are third party (eg AccuPro) universal dividing heads on the
market. My question is, how do these third party dividing heads
get their drive from millers of unknown manufacture? Or to be more
specific, how would I drive one of these dividing heads on my miller
with no power feed?
