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.

The ones I remember being called "Chuckers" were like scaled up "swiss
automatic" lathes which, once set up, would create and part off an
entire turned/threaded piece without operator assistance, other than
shoving a new bar of stock into the back end of the spindle when needed.
I think I've seen ones which even did that stock replenishing by themselves.

A chucker is a "second op" production machine. Used to finish parts
started on bigger machines by doing such jobs as internal and external
threads etc. Made obsolete by cnc machines.

A chucker is a production machine. It may have multiple spindles. It has a
number of different tool holders and attachments that allows it to make many
different, complex parts. For example: bar stock is loaded, pushed out to
desired length, faced, and cut down to two different diameters. Then a ball
turner is applied to round off the middle, followed by drilling through with
several steps, o-ring grooves, and then cut off. It is like a screw
machine writ large. It is called a chucker because it typically feeds bar
stock through the spindle into a chuck.

Simply put Mike, a "chucker" is a lathe that has no tailstock. These are
normally production machines meant to run short-length parts, or collet
equiped machines.

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.

Every lathe is a chucker...just leave the key in and turn it on.

How many chuck keys can a lathe chuck chuck

Yeah, most of them are Hardinge's, and the goddamm price *never* goes down!
Very nice to work on.

Often have handle-actuated turrets, sometimes a separate parting attachment,
and nice motorized powerfeed in x,y, continuously variable spindle speed,
coolant, you name it....
And inlaid *ivory* on the goddamm handles!! No foolin....

Proly you could put a live center in the turret, using it as a tail stock if
you had to. iirc, the beds weren't *that* short, and you could turn a shaft
mebbe 18" long or so.

For small parts (or at least some of the ops), proly the only way to go,
short of very expensive/sophisticated CNC, and then sometimes not even
then....

There's a shop in LI that has I think nearly a hundred of these chuckers,
does excellent work, usually ahead of deadline, if you can bleeve dat....

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.

If it's mounted vertically, do you have a up-chucker?

If you put a piece of wood in a chucker do you get a wood chucker?

If it's mounted vertically you get a "vertical-up-chucker."

If it's and automatic you get a
"auto-vertical-up-chucker"

If it's a semi-auto, Mike Berger wants it banned.

Shucks. Makes a bloke want to chuckle.

How many keys can Chuck leave in a lathe chuck

Chuckers..HCs..Hardinge..seem to be going for about $1000-1500 here in

In short, chuckers don't have tailstocks, or tailstock turrets.

The turret is mounted on the bed, in place of a cross slide.

Basically if you took your standard southbend lathe, threw
out the tailstock, and mounted a four position toolpost on
the cross slide, that would be a primitive chucker.
