Abstract
The invention provides an improved unbalance measuring machine wherein the drive member for imparting rotational forces to the workpiece has two distinct positions of engagement with the workpiece. A first position is used to maintain minimal contact with the workpiece and maintain a steady-state rotation of the workpiece. A second position is used to impart additional rotational forces to the workpiece for the purposes of accelerating, decelerating and indexing the workpiece.
