Ok i need help im a newbie. If i bought a micro mark were should i purchase the ball screws for xyz axis. I want to mill turbines and compressors with dimensional tolerances of about +/-0.001 if possible and overall working accuracy +/- 0.0005 if this is right. Also can i mill turbines and compressors with a 4 axis by adding rotary table to micro mark or do i need 5 axis? Here are some pics of what my designer did for me. Somebody please give me a starting point.
