They're a small shop, this will be their first swiss machine. I'm doing a 500 piece capability run after holding a cpk of 2.92 on a +/- .001" feature on a 30 piece run. 17-4 stainless, the endmill cutting the flat lasted 300 pieces before it started pushing a burr, but 2 turning tools and the cutoff tool still going strong at 450 pieces. I've moved 2 offsets <.0005 and that's it.

OAL is just under 2.25, smallest OD is .084"

No issues with vibration; we can tweak the center height (Y axis) of the turning tools and that makes a huge difference.

What machine is it running on?

A Nomura swiss. 25mm UB8-K2 specifically.

Always heard Nomura was a good machine, never had any experience with one
