Precision parts machining shops are increasingly-faced with the need to accept higher mix/lower volume work. Putting a job on a machine tool and running it for long periods of time is becoming rare because the definition of medium and high volume lot sizes "ain't what it used to be."

In a turning application, one area where time saving strides can be made is workholding, generally found in the form of universal clamping devices such as the three-jaw chuck.
