Schaublin 125-CNC retrofit.

Oh. Doh!!!!!

Thanks a lot. I was so focused on the comp, I missed the obvious.

Blame this on me, despite me writing this a few posts back:

I was convinced the comp issue is separate from this one, and was wondering why are you testing the comp since it is not mentioned in the error report...
Should have raised a flag ... or a smoke signal, wold have probably been more useful.

I really needed a slap upside the head!

No you do/did not, i have plenty such stories where i missed things in front of me, that is normal and utterly human, especially when we deal with complicated stuff and put all our attention sometimes in the wrong place!
The thing i am consistently working on and having issues with, is get better at explaining things and get over the "typing" lazynes.

Thanks a lot for your help and advice guys. I got the turret.comp finished and working really nicely. (Attached)

Here is a video of it in action, doing it's first production run...



Cheers,

Thanks for the vid Mark!

Couple of unsolicited thoughts...

• I wonder if part of your threading inserts were dying because they're designed for RH helix instead of LH? Probably not, but I have to wonder.
  • I also saw what looked like a million threading passes.  Perhaps your aren't taking a deep enough cut per pass and rubbing?
• Looks like your pneumatic chuck has adjustable serrated top jaws.  Instead of turning a new step diameter so far out that you run in to the holes, maybe move the top jaws out a couple of serrations?  My Rohm is similar and has a specification on how many serrations you can overhang before they get dodgy.
• Birds-nesting during facing... just cut from OD to ID instead of both directions. That inner step was so shallow you should be able to just plunge in Z- and cut to the ID.

Nice job on the tool changer!
