Abstract
A machine tool system of the present invention includes a rotatable spindle capable of releasably gripping a bar, a pusher that biases the bar from a rear end thereof toward a front end thereof to be movable together with the bar in a Z1-axis direction thereof, and an abnormality determining unit that determines whether an abnormality occurs by monitoring movement of the pusher in the Z1-axis direction. The spindle is movable in the Z1-axis direction, and the abnormality determining unit determines that a first abnormality occurs when the moving distance of the spindle differs from the moving distance of the pusher in a state that the spindle grips the bar.
