On its face, bore grinding seems like a simple operation. You send a spinning wheel inside a spinning part and oscillate it back and forth until the desired dimensions and surface finish have been achieved. Unfortunately to reach into the part, the wheel must be mounted on a quill (sometimes longin essence, a cantilever). You want the bore to be perfectly straight and perfectly round.
