I bought a drill chuck recently; it was attached to this unidentified arbor.
I wondered if someone could tell me what machine this would suit?
The markings are "Fanuc" "Big" "30-J6".
There is a large ball bearing on the arbor, I presume it is used by a tool changer?
Thanks for any help.

It would "suit" any spindle and changer with matching taper and same-family of pull-stud.
......Vancbiker,Thanks for the P&W suggestion....
The toolholder you have is definitely not for a Chiron. I had the unfortunate experience to be an FSE for a Chiron distributor for a couple years. Without a doubt the most troublesome toolchanger I ever saw on a "modern" machine tool. Very maintenance intensive. Chip contamination being by far the most common cause of trouble.
Poorly worded question perhaps - I would like to know what machine it was originally made for. The large bearing makes it fairly machine specific I am guessing.
... a nice Japanese drill chuck on it "Yukiwa Heavy Duty Ball Bearing Super Chuck", a new name to me.
.....BTW, this arbor had a nice Japanese drill chuck on it "Yukiwa Heavy Duty Ball Bearing Super Chuck", a new name to me.
Best outcome would be that the nice chuck has a standard arse-end that readily fits <whatever other > toolholder you - or a potential purchaser/trader - actually have a machine for.
One very nice feature of the arbor is the jacking nut for the chuck - what a great idea.
A ring with enough beef to break-loose my 5 MT goods would take up a LOT of scarce space right on the machine. The wedge, lever, and "ratcheting" differential drifts for all that OTOH only take up space in the box!
Just to remove drill chucks from their Jacobs taper ....
