Abstract:
1. A balancing machine for mounting to a machine tool to correct a rotational imbalance of a workpiece comprising: a first workpiece support for retaining said workpiece from moving in a first axis direction and allowing said workpiece to rotate while translating in a second axis direction, said first workpiece support having a base section for attaching to a mounting surface on a moveable table of said machine tool, wherein said mounting surface is substantially perpendicular to said first axis direction; a second workpiece support for retaining said workpiece from moving in said first axis direction and allowing said workpiece to rotate while translating in said second axis direction, said second support coupled to said base section, wherein said second workpiece support is disposed spaced from said first workpiece support along an axis of rotation of said workpiece; and a belt tensioning pulley coupled to said base section for tensioning a drive belt for rotating said workpiece, wherein said belt tensioning pulley directs said drive belt to hold said workpiece in contact with each of said first and second workpiece supports with forces directed substantially in said first axis direction.
