Abstract
A jaw exchanger includes a stocker configured to store jaws which are configured to be attached to a chuck body of a machine tool, a stocker movement mechanism configured to move the stocker between a first position and a second position, and a jaw transferor configured to transfer the jaws to the stocker positioned at the first position from a jaw receiver to receive the jaws, and configured to transfer the jaws to the chuck body from the stocker positioned at the second position. The chuck body is rotatable about a rotation axis.
