<p>An apparatus is provided which enables the jaws of a chuck 10 to be removed from and inserted into jaw-ways 12, 13, 14 using a conventional workpiece handler, rather than a sophisticated and highly accurate dedicated jaw handling mechanism. A conventional workpiece handler cannot position a jaw to close tolerances but this problem is overcome by using a guide shoe 17 which can receive a jaw from the workpiece handler in any one of a range of positions and then accurately guide the jaw into one of the jaw-ways 12, 13, or 14.</p><p>A mechanism 16 is provided for releasing the jaws from the jaw-ways, and for re-locking the jaws in position.</p> |
