a face driver is a type of lathe accessory that is used to hold and rotate a workpiece during the turning process. It is typically used for holding large, heavy, or irregularly shaped workpieces that cannot be held securely with a traditional chuck.
the face driver consists of two main components: a center point and a set of driving pins. The center point is inserted into the center hole of the workpiece, and the driving pins are inserted into holes or slots on the face of the workpiece. The face driver is then engaged, causing the driving pins to press against the face of the workpiece and rotate it.
the rotation of the workpiece is controlled by the lathe's motor and gearbox, and the cutting tool is brought into contact with the rotating workpiece to remove material and shape it to the desired dimensions. The face driver ensures that the workpiece remains securely held and does not slip or move during the turning process, which is important for achieving precise and accurate cuts.
