Abstract
A crankshaft miller is constructed by providing two cutter units movably in a longitudinal direction of a work between a pair of work heads provided on a bed and supporting both ends of the work. A cutter for machining a main journal and a first resting device are provided in one of the pair of cutter units. A pitch of the cutter for machining a main journal and the first resting device is selected such that when a counterweight is machined by the cutter for machining a main journal, a main journal which is located adjacent a counterweight forming a pair with the counterweight is clamped by the first resting device. A cutter for machining a pin journal and a second resting device are provided in the other of the pair of cutter. A pitch of the cutter for machining a pin journal and the second resting device is selected such that when a pin journal is machined by means of the cutter for machining a pin journal, the main journal adjacent the pin journal is clamped by the second resting device.
