The present invention relates to a machine for machining crankshaft (5) ends, which comprises two machining heads (1, 2) designed to machine crankshaft (5) ends and two machining stations (3, 4) designed to receive and secure at least one crankshaft (5), said machining stations (3, 4) being disposed between the two machining heads (1, 2). The crankshafts (5) will be mounted in such a manner as to be disposed parallel to each other and oriented at 180º. Additionally, the machining heads (1, 2) are designed to be positioned facing the ends of the crankshafts (5) of the machining stations (3, 4).
Additionally, the invention relates to a crankshaft (5) machining process based on the fact that both machining heads (1, 2) alternately machine flange ends (9) and spike ends (8) in the crankshafts (5) secured to the machining heads (3, 4). In this manner, the machine machines crankshafts without stopping between the machining of two successive crankshafts.
