Abstract

A machine tool for machining crankshafts (200), including, arranged in the same horizontal plane on a frame extending along the transfer axis (arrow A) of a machining line (C), a machining station (P1) with two tool holder discs (110, 120) for machining the crankshafts (200), and two parallel work stations (S1, S2) arranged upstream and downstream from the machining station (P1) for rotating the two crankshafts, whereby the tool holder disc (110, 120) of the machining station, movably mounted (arrow X) along the transfer axis (arrow A) can move back and forth between one work station (S1 or S2) and the other (S2 or S1) and machine a crankshaft (200) at a work station (S1 or S2) during the auxiliary operations needed to position a new crankshaft (200) in the other work station (S2 or S1), and vice versa. An operating method and a machining line comprising such a machine tool are also disclosed. Said machine tool is useful for turning/shaving crankshafts for engines with four in-line cylinders.
