The problem addressed by the invention is to provide a milling machine which can be used to machine eccentric end faces and peripheral faces and which ensures a short machining time despite its simple design. A milling machine of this king for machining workpieces and with means of clamping eccentric end faces or enveloping surfaces, e.g. of a crankshaft (1), with a bed (20), with two mutually facing chucks (21, 22) to accommodate the workpiece (1), at least one of these chucks being rotatable and positionable (C1 axis) by means of a headstock (23, 24), with a tool holder (25, 26) which can be moved at right angles to the Z axis and has a rotatable milling cutter (5, 6), and with a control mechanism is characterized by a plurality of tool holders which can be controlled independently of each other in terms of both milling cutter rotation and travel in a transverse direction, and in that the control mechanism controls not only the rotation of the workpiece but also the transverse movement of the tool holders and the rotation of the milling cutters.
