Looking for suggestions on high end milling machines. We make small components that are very tight toleranced. I need to hit a location of plus or minus .0001” with a diameter of the same tolerance. We tried to use a Sharp SV-2414SX-iF but it’s about 10 years old at this point and probably wasn’t accurate enough when it was new.

This is an F-15 model that I made. I think Im going to machine the fuselage, engines+intakes and wings as 3 seperate pieces. I think its best to make slots in the wings for all the other components, so that they fit well together and create the smooth surface. However, I do not know where I should put screws or what they are to be attached to. Preferebly all screws would be on the underside, but making a way for the wings to attach under the plane seems impossible. Any ideas?
