    Nail polish remover or Acetone will work. Heat will also break it down. Heat like from a propane torch

   Heat, as noted, will work but it only needs to be a around 300 degrees (F) maybe less.  Using a torch is fine but you won't have to heat the parts red hot.  Heat the part while applying torque to the screw will pop it loose with the least chance of doing damage.  In theory burning super glue creates cyanide gas so a little fresh air while you wield the torch would be a good idea.

   I did pour acetone on it-let it soak for a bit and tried it but no luck. Tried it a couple of times. I don't know if you know anything about turning but its a Oneway Talon Chuck.

   The acetone works on fresh super glue that hasn't cured. A few hundred degrees of heat should do the trick.  Heat will break the bond of most adhesives including epoxy and contact cement.  You might put it in an oven as long as there is no plastic. I do have some idea of what you have as I work on machines.

   I have a bottle of debonder that I got from my supplier. I thought I would see if I could sniff it to tell if it was lacquer thinner or acetone as rick suggested, but I don't think it was either of those. It seemed like there was a hint of alcohol, and I'm not sure what else, maybe methaline-cloride, which would be my best guess. I think that is the solvent-adhesive for plex.

   This reminds me of my old friend, Harry, who once, under the pressure of an 'important' meeting, attempted to reglue one of his front teeth (it was a fake on a gold stud) back in place.  Needless to say, the immediate result was the tooth firmly afixed to the stud, and his thumb and forefinger firmly affixed to the tooth...

   Your story causes me to try to beat it.  The following is true!  Working as ER doc, a man came in saying that he kept a tube of ointment at his bed-side for his itching ear.  In the dark he mistakenly grabbed a tube of super glue and filled his ear.  When I saw it the glue had hardened to a glassy state.  He had to go for surgery, having the glue removed with a dental type drill.  Life is full of interesting  events.

   ROTFLMHO.  One more like that and I'll be forced to tell the whole Harry, his tooth, the crazy glue, the razor blade, and the file story.  ;-)

   Well, first you have to know Harry.  One of those 'larger-than-life' characters that everyone should have the privilege to know.  He had been a professional ski instructor, a bouncer, a boxer, a bike racer, he was probably 6'2, a well-built 6'2.  When I knew him he was a superb, hands-on engineer, as comfortable with a Bridgeport as with a calculator.  Oh, he was a womanizer par excellence (but, previously noting his experience a a ski instructor, I repeat myself ;-) )

   Somewhere in his checkered career, he'd lost an upper front tooth (one thing he and I had in common).  The difference was that Harry had a colossal set of choppers, while mine are far more refined.  (In fact the first day on the job at that company mine was missing, and nobody noticed.)  So, on this particular day, when Harry had to meet with various and sundry high-level types coming from an unhappy customer, his tooth fell out. 

   What to do?  Couldn't call off or delay the meeting.  Couldn't get to a dentist, the ever unflappable Harry did the next best thing; a drop (oversized one might suppose) of Crazy Glue into the 'tooth' and a quick stuff up onto the gold 'pivot'.  Slick as could be, it was done.  Then he attempted to let go of the tooth...  Nada.  His fingers were stuck as fast as a sailor would hope the anchor was when anchoring off of a lee shore...

   So, with thumb and forefinger stuck to his tooth, he headed to the bench where a variety of items like small tools, incidentals, etc were kept, and requested a razor blade.  With said item in hand he repaired back to the 'facilities', to gaze with wonder upon his predicament.  Note, of course, he was right-handed, and his right hand was now stuck, useless, in his mouth.  So, with no little fear and trepidation I'm certain, he commenced cutting his thumb and finger away from the tooth by sliding the blade in between.  First his forefinger, then his thumb and, with minimal blood loss, he succeeded. 

   But, if you can remember when you last lost a tooth, or perhaps a filling, you know what happened next.His tongue found all the rough bits on the back of the tooth, and the rough bits on the front of his tooth irritated the back of his upper lip.  Harry wanders out the door, procures a very fine file, and returns to the mirror to smooth things up as best as he can.  So, staring into the mirror, working on this tooth, he progress was interrupted when some new comer (no, not me) walks in to the john and is, as you might imagine, totally taken aback at the sight.  Never one at loss for words, nor even missing a beat, Harry allows, "The food's a bit tough in the cafeteria."

   Unrelated, but another great Harry story:  When he retired there was a mega going-away/retirement party for Harry.  A big hall was hired, there were people from all over Harry's past in that room.  People that 'knew' Harry, LOL.  Those that knew Harry knew of his womanizing past so, on the QT, they arranged for a stripper.  Harry is up on the stage, barely able to contain himself as the stripper does the routine.  Well, when the top was dropped (back to Harry) his enthusiasm got the best of him, so he jumped up and wrapped his arms around the stripper, only to find out what the others all knew, the stripper was a male.  Ah, but Harry took it all in good stride.  Hell of a guy.

   Request the MSDS sheet and it should tell what's in it. We buy super glue in 5 gallon buckets and the accellerator is acetone based. I just use acetone as a debonder. We don't seem to have the problems of sticking things together that other folks do.

   Soak the chuck in lacquer thinner (Any paint store) in a CLOSED container for an hour or longer It evaporates very fast, if not contained Do it outside the house or shop. Steinmetz.

   Be careful with the lacquer thinner, it will attack many plastics and finishes, and it will remove any oil or grease the chuck needs to function smoothly.  The chuck could have some plastic in it for bushings or anti friction washers.  I would soak the entire chuck only as a last resort.

   I went ahead and heated it a bit at a time and sure enough, the goop caught fire, sizzled and smoked and out came the bolt...heating it up with the propane torch just enought to cook the cyanine did the trick.
