I don't think you're likely to find a machine of the desired resolution on a university student's income. Not meaning to rain on your parade, but most of your mid-range ($60K-$100K)industrial machines only have .0002 unrepeatability, and it's quite a leap to go from university student to toolmaker/die-sinker. Unless you have a solid background in machining and machine theory, you're setting yourself up for a big disappointment.
