I have a part here with an accurate shaft for pre-loaded spindle bearings, and an inside diameter on the opposite face from the shaft, for mounting a hub. The part must be machined in the lathe, then re-chucked to do the opposite feature. I am using the shaft as my datum, and I have applied a positional tolerance of Ø0.05mm on the inside diameter. It appears that our machine shop used every bit of this. This particular shop is fast and cheap.
How accurately can a shop centre a part in a lathe, when they re-check to a datum feature?
