ABSTRACT:
An adapter for rendering a live center for machines adjustable for adjustable centering of work pieces may comprise a generally conical body having a conical recess formed therein and adapted to receive the conical extremity of a rotatable live center element of a live center mechanism. A conical surface may be formed at one extremity of the conical body and may be disposed for receiving contact within the center hole of a work piece. The generally conical body may include pivot means internally thereof which may be disposed for contact with the conical extremity of a rotatable live center element. An adjustment mechanism may be provided for the conical body and may also engage the rotatable live center element, the adjustment mechanism being manipulated to impart controllable pivotal movement of the body relative to the rotatable live center element to achieve controlled shifting of the axis of the adapter relative to the axis of the rotatable live center element.
