Question: How far can a 1-1/4" boring bar make it into a 3" OD 6061 blank that doesn't have a drilled hole?
Answer: Surprisingly far!
These blanks have a 1.69" hole drilled in one end, and the boring bar is supposed to finish the bore to 1.753". Get distracted, put the blank in the wrong way, hit the button, start to walk away just like you did a hundred times before, and you hear that funny groaning, chomping noise .
The machine didn't even stall out or overload the servo. Boring bar was fine other than being pushed back in its holder a little. Replace the insert, reset the offsets, and good to go.
Regards.
Mike
