grinding crankshafts?

["Watry, Andrew (LNG-MBC)" <Andrew.Watry@domain.elided>]

This is a general question, not Alfa-specific, that has bugged me for
years/decades. I can imagine how a machine shop grinds the main journals on
a crankshaft, because they are on a common center/axis with the shaft
itself, so you can basically stick it in a lathe and turn it.  Is that how
it works? But how does a machine shop grind the rod journals, which are
off-center and have no chuckable axis? I can't picture how it would work.
Thanks
