Abstract
(EN)
A jaw replacement device according to the present invention comprises: a stocker that stores a jaw for mounting on a chuck body that is rotatable around an axis of rotation; a stocker movement mechanism that moves the stocker between a first position and a second position; and a jaw delivery device. The jaw delivery device is capable of delivering the jaw from a jaw-receiving device, for receiving the jaw, to the stocker at the first position. The jaw delivery device is also capable of delivering the jaw from the stocker at the second position to the chuck body.
