"Stages" apply to motion as in a system; generally referred to as X, XY, XYZ and rotary.  The basic function of a stage is to constrain motion to a defined direction.

Motorized rotary stages are used to precisely position objects around a rotation (circular) axis.  Motorized rotary stages are particularly suited to laser cutting, laser welding or laser marking applications on tubes, cylinders, or odd-shaped packages.
