Claims

[Scope of utility model registration request]

A pair of center thrust rollers rotatably attached to a holder rotated by a drive mechanism are brought into pressure contact with a pair of opposing workpiece surfaces of a crankshaft by the rotation of the holder, and the crankshaft is rotated. The crankshaft processing device for hardening the surface to be machined includes a detection means for detecting the amount of vibration of the center thrust roller, and a detection means for comparing the output of the detection means with a reference signal to determine suitability and output a control signal. 1. A crankshaft processing device comprising: a control circuit; and a notification means that operates in response to an output signal from the control circuit to notify an abnormal state.
