It was a CNC drilling operation gone bad I guess. Anyhow, I was presented several discards for possible salvage.
I mounted the chucks in the lathe and faced off the face and chuck teeth with a carbide cutter. Interestingly I was able to
save both of them and even the drill bit. Sure the snouts of the chuck are a little shorter but that's way better than
having paperweights! I have been using them and they are quite usable now. P1020562.JPGP1020638.JPG
Apparently it is the norm to leave the CNC machine work while the operator is at another task or taking a coffee break or something. I wouldn't know
because my shop has only manual machines. I made a little JT arbor with a straight shank so I would be able to use it. The other chuck I saved as
well. The chucks came from a tool and die shop that a friend of mine works at.

You can see from the first photo that the drilling operation ran up to the chucks and turned into some sort of friction welding operation.:eek 2:
 
Any n all USA made super chuck is worth saving. Parts are out there if needed , not cheap but worth it.
