Live tooled lathe vs. Mill

[tdahlstrom]

We make disk shaped parts with both face holes and side holes. I am trying to decide when it is better to use a live tooled lathe, or a mill/drill center. Can some one share some of the factors they considered in making the same decision? Is there any "rule of thumb" from experience in regards to # of live tools required, # of turn vs. drill features, etc.

One thing to definitely consider on a live tooling machine is a "Y" axis which will allow movement of the tool toward and away from you horizontally if you are standing at the machine door. Otherwise, without the Y axis you will be unable to drill holes or machine features on the circumference that are not on the main spindle centerline.
A sub spindle in lieu of a tailstock is a must. Don't make the mistake of overlooking this. The payback begins the moment you start using it. Just my 2cents.
