Abstract:
1. Eccentric work piece holder adaptable to rotary unit, said rotary unit having a rotary axis for rotating a work piece during operations, said eccentric work piece holder comprising: a first aligning member fixedly mounted on said rotary axis of said rotary unit; a second aligning member mounted for substantially X-directional pivotal movements along said rotary axis, said second aligning member being arranged adjacent to said first aligning member; a third aligning member having a bore opening for holding said work piece, said third aligning member being mounted for substantially Y-directional pivotal movement along said rotary axis, and wherein said third aligning member being arranged nearest adjacent to said second aligning member; whereby rotary movement of said first, second and third aligning members along said rotary axis causes said work piece secured in said third aligning member to align relative to said rotary axis in response to pivotable movements of said second aligning member in said substantially X direction and pivotable movements of said third aligning member in said substantially Y direction, thereby compensating for work piece runout in said X and Y directions, where the X direction and the Y direction are perpendicular to one another and the center line of the rotary axis is perpendicular to both the X direction and the Y direction.
