Machine and method for deep rolling annular fillets of journals of metallic workpieces, such as the crank pins of an engine crankshaft in which the crankshaft is loaded into a center positioned turning lathe, and left and right hand banks of floating jaw units located on opposite sides of the lathe are moved from a first station in which crankshafts can be loaded on or unloaded from the lathe to a second station in which inboard jaw ends of the jaw units with fillet rolling tools aboard are operatively engaged under load with each of the pin fillets, which are then simultaneously rolled as the lathe motor turns the crankshaft about its rotational axis and the tooling carried by the floating jaw units orbits the axis and completely deep rolls the fillets.
