Zusammenfassung:	The invention relates to a crankshaft production machine for producing crankshafts (15), which have centric and eccentric surfaces to be machined a nd which are held in a manner that enables them to rotate about a C axis (5, 6) . Said machine comprises a headstock, a counter spindle or a tailstock, at lea st one displaceable longitudinal slide (17, 18) and drive units having motors f or driving the crankshaft about the C axis and for advancing subassemblies for tool spindles (8, 11) and the tools. The motor in at least one drive unit, which serves to drive tool spindles (1, 3), and in at least one drive unit, which serves to drive tool spindles (8, 11), is provided in the form of a torque motor (2, 4, 10, 13).
