You raised a good point as that is why there are allowances and clearances included in the design of equipment.
You could also perfectly tram in a mill, even the world class Deckel, one day come back the next and find it out. This would be due to temperature differentials from one day to the next unless you have a perfectly controlled environment like they have in a controlled environment inspection room.
As a tool maker I was so ingrained with the "it must be within a hair of a gnats behind" I wanted everything that way, somethings need to be, but not every thing.
Good luck on tramming the mill. Let us know how it comes out.
