  • Patent number: 11794309
    Abstract: An automated vise is disclosed. A gross moveable jaw drive has a stroke longer than the stroke of a fine moveable jaw drive. With this construction, the gross moveable jaw drive can be utilized to actuate the one or more moveable jaws of the vise over a distance greater than the fine moveable jaw drive stroke to a position in which actuation of the fine moveable jaw drive is capable of positioning the one or more moveable jaws in a clamp position to apply pressure to hold the workpiece for machining by, e.g., a CNC machine. In this way, the automated vise can account for workpieces of differing size.
