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.

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

They're great machines... I've been in manufacturing for 35 ish years, the past 10 years has been working for an Okuma distributor who also is the Nomura distributor for North America. 2 years ago they decided to make me an application engineer for the Swiss line. I've worked with Citizens and Stars for a few years, and now Nomuras. I'd pick Citizen and Nomura for ease of use, functionality, capability. But Nomuras are far and above a better price across the board. This year they're rolling out a 26mm series on a few models for the American market, making it possible to run 1" stock. I don't know if we'll have one for IMTS this year or not. Fingers crossed!
