In state-of-the-art manufacturing, the characteristics of a workpiece may make the orientation of the workpiece necessary. For example, holes for gear teeth or crankshafts are oriented radially.
To prevent the cooling lubricants merging / mixing, the workpieces need to be cleaned automatically. Various options are available, depending on the customer's requirements and the workpiece. Rotationally symmetric parts are spun; other parts are cleaned by vacuuming or blowing.
