If memory serves me correctly, a Warner & Swasey 2S was defined as a
"chucker". I programmed same for a few months,
and it was equipped with a bar feeder. Had a 6-station tool turret.
Basically any job that could be fit into it's working
envolope was possible, whether starting from raw stock or follow up
operations.

How does a "chucker" lathe differ from other types?

I know about turret lathes, engine lathes, toolroom lathes...
I've tried to tell from pictures and references on the net,
but I still don't really know what a "chucker" is used for.


If you haven't figured it out yet, you're not going to get a straight
answer g. Chuckers can be single or multi-spindle, manual or
automatic, horizontal or vertical, big or little, pink or blue. I'd say
the only thing that all chuckers have in common is that semi-finished
parts are loaded singly (i.e., no bar feed), and there's some sort of
tool changer, or multiple tool stations in the case of a multi-spindle
machine.

In it's simplest manual form, I'm not sure where you'd draw the line
between a chucker and a turret lathe with no bar feed. I've owned both a
J&L saddle type turret lathe and a chucker similar to a Hardinge HC.
Except for the fact that the turret lathe must have weighed 15000
pounds, and the chucker perhaps 1500, it'd be difficult to draw a
distinction between them.
