ことを特徴とするチヤツキング装置。 A chuck that rotates around a main axis, and an indexing board that is clamped and unclamped to the chuck and holds a workpiece having a plurality of machined holes along the vicinity of the outer periphery, and that rotates eccentrically with respect to the rotation center of the chuck. When indexing the machining hole in the workpiece, the center of the machining hole in the workpiece is made to correspond to the center of rotation of the chuck by rotating the indexing plate in an unclamped state by a predetermined angle with respect to the chuck. In the device, a pressure generating means is provided at a location on the outer periphery of the indexing disc where the centrifugal force of the indexing disc generated by the rotation of the chuck is large, and A chucking device comprising: control means for applying pressure in the direction of centripetal force to the pressure generating means to cancel the force.
