ABSTRACT:
An apparatus for the internal chucking of a soft three-jaw chuck on lathes is provided to enable the three jaws to be positioned so that they can be bored out to a high precise chucking dimension. The apparatus includes two rotatable triangular clamping plates that are disposed in any preselected rotational position relative to each other. The plates each have an external configuration of an equilateral triangle and are adapted to be received in the soft three-jaw chuck in a desired angular position such that common positions of contact result from the jaws of the three-jaw chuck from the edges of the two clamping plates which are canted one relative to the other. The desired chucking dimension range is covered by the relative dimensions of the two clamping plates.
