Known machines for the machining of crankshafts, in which the machining units for the machining of the crankshaft are supported and moved by operating crankshafts, are not adjustable to different offset angles of crankshafts to be machined. Therefore a machine is proposed for the machining of crankshafts with means for the guiding and taking along of a crankshaft to be machined and with at least two movable devices for the uptake of machining tools or systems, the devices being supported and moved by crankpins of two driven operating crankshafts consisting of several cranks and mounted on main bearing pins, where the individual cranks of each operating crankshaft are fixable relatively to each other and comprise two independent main bearing pins each and are mounted thereon for rotation relative to each other.

In a crank rolling machine adapted to be adjusted for rolling of the crank fillets of cranks of a variety of different angular configurations, said machine including means for rotatably supporting a crankshaft to be rolled, rolling means for applying rolling forces to said fillets, first and second control crankshafts operatively connected to said rolling means for controlling the rotated position of said crankshaft to be rolled in accordance with the rotated position of said control crankshafts, drive means for synchronously rotating said control crankshafts and said crankshaft to be rolled, the improvement which comprises said control crankshafts each comprising a plurality of crank sections, said sections being relatively rotatably adjustable one to the other about the axis of rotation of said control crankshafts, whereby the angular orientation of the crank sections of said control crankshafts can be adapted to process crankshafts of a variety of configurations.
