Accuracy of Bridgeport 412x?

[swarf_rat]

Does anyone know what the claimed positioning accuracy of the HH 2500 controlled 412X was when new? I assume it has HH rotary encoders on SEM motors and belt driven ball screws, like the other Interacts?

OK, thought someone would have the manual and just be able to look that up.

Anybody know the actual accuracy from experience?

Should Be Plus /minus .0002

OK, thanks. That is about the same as the Series I Interact knee mill I had a while back. Is that from the book or experience?

I remember seeing it in the manual.
