Abstract
A spindle characterization system for characterizing performance of a spindle used in an industrial machine includes a machine base for providing a mounting and support surface and having a recessed portion. The spindle characterization facility includes a table base assembly for supporting the spindle disposed within the recess portion and the table base assembly has a table top and height adjustment mechanism for adjusting the height of the table top. The spindle characterization system also includes a spindle mounting mechanism having a top portion mounted to the spindle and a bottom portion mounted to the table top, and a spindle forcing assembly operatively connected to the spindle, and the spindle forcing assembly generates an axial load, radial load and a torque that is applied to the spindle to simulate a machine tool load. The spindle characterization facility further includes a programmable controller operatively connected to the spindle forcing assembly for providing computerized numeric control, and a computer system in communication with the programmable controller.
