ABSTRACT:
A crankshaft machining apparatus for use in machining a crankshaft from a workpiece, includes: a bed; a pair of work heads mounted on the bed for fixedly supporting the workpiece to be machined at both ends thereof, respectively; at least one cutter head disposed between the work heads so as to be displaceable in an axial direction of the workpiece; and an inside edge cutter mounted on a said cutter head for cutting in the workpiece simultaneously a pair of counter weights of the crankshaft along their respective outer peripheries, the counter weights being located at both ends of a pin journal of the crankshaft, respectively. This arrangement has the ability to form the outer peripheries of a pair of counter weights simultaneously, and provides a markedly enhanced machining efficiency.
