The only machining that MIGHT be required is to turn down the non-structural pilot on the face of the flange, the only purpose of the pilot is to center the drum or rotor on the hub. Obviously you don't want to do anything that might weaken the hub. In reality, the hole in the center of the rotor will likely be larger than the pilot on the hub. You are more likely to need a machined ring between the rotor and the hub.
