ABSTRACT:
A chuck for clamping a discoid portion of a work piece includes a base, at least two fixed clamps secured on a front end surface of the base, a movable clamp adjacent to the front end surface of the base and a pin secured to the front end surface of the base. The pin is adapted to fit in a hole formed in the discoid when the discoid is mounted on the chuck wherein the hole has a larger diameter than the pin. Furthermore, the pin is positioned radially inwardly of the movable clamp toward the chuck center and oriented so that the two fixed clamps are equiangularly spaced about and equidistantly spaced from the pin. As a result, the discoid may move relative to the pin and toward the two fixed clamps, without rotation thereof. Accordingly, the centroidal axis of the discoid may be aligned with the rotational axis of the chuck so that precision machining may be achieved.
