Just learning about the possibilities now. I found this: https://www.youtube.com/watch?v=9XRnVvJTj20 Surface finish of 1 thousandth of a micron (1 nm). Beautiful

I am not saying that I know exactly what and why I want to do it, but my idea was to have this turbine made with air bearings, and for that I thaught I needed a micron class machineso I do not have to go for grinding phase of the shaft etc... I am also looking for inexpensive (if they exist) EDM machine with rotation, so I can make thin slicing of the rotor (like in Tesla turbine). If anyone has a recommendation...I would be grateful.

I looked at Haas first and was pleasantly surprized by their prices. They have them right there on their website for anyone to see. Their Mini is in the $30k range. I am trying to get info on Kern factory refurbished Micro machine for las two weeks. Unlike Chinese (which reply to inquiries within minutes) I was waiting for the reply from Cazeneuve for two three weeks. The future looks bleak.

Hi everybody, I am new here and new in CNC machining. Looking to buy a small CNC machine for hoby - garage type of work. Looking to make prototypes of some turbines with air bearings. So micron precision is a must, I believe. After I looked into Kern, Haas I found out that they have, so called, Mini or Micro machines. Small but pretty accurate. Haas, not that expensive (around $30k) which is my range. Can anybody give me an advice if there are similar options within similar price range by any other CNC 5 axis manufacturers?
