<p>PROBLEM TO BE SOLVED: To provide a chuck device which can hold a plurality of types of objects to be processed with different sizes and shapes, and can also shorten a preparation time before processing of an object to be processed and can secure processing accuracy of the object to be processed.SOLUTION: A chuck device 1 includes a chuck claw 4 which can move in a diameter direction, and a claw member 6 which is detachably fixed to the chuck claw 4. The chuck claw 4 includes a radial abutting part 4b having a first abutting surface which can abut on an outer side surface of the object to be processed in the radial direction, and an axial abutting part 4a having a second abutting surface 4d on which one end surface of the object to be processed in an axial direction can abut and which is integrally formed with the radial abutting part 4b. The claw member 6 is fixed to the chuck claw 4 in an abutting state on the first abutting surface and the second abutting surface 4d. The claw member 6 has a third abutting surface 6b which abuts on the outer side surface of the object to be processed in the radial direction.</p> |
