CAT45?

Not very popular from what Ive seen.. Hell, I still have a box of 45t tooling sitting up on a shelf that I can't get rid of.. Probably going to hit the scrap yard soon :/

I have a 5 gallon bucket full as well--IIRC these were fairly common back in the day when cintimatics were the workhorse machining centers.

Gimmee $20 + postage and I'll toss into a flat rate box.......

Yup Cincinnati had'em thou out the 70's,80's + being not too common they were $expensive$ in the day. Today? hello scrap man :-)

or JoeAuto, make a drill press spindle for'em out of an old Cincy sittin in a corner somewhere.

IIRC the Cincinnati models were 5Vs 10V's 15V's & later Saber's using Acramatic MC(big blue), 900 & 850 controls. wonder what happened to'em all?

I ran a 4 axis sunstrand with that controller on it.....back in ~1984 or so--what an abortion...motor generator dc spindle drive setup and a vickers hydraulic pack running about 30 hP

--But hardly anybody had contouring rotary axis capability back then so the work just kept coming in....
