To increase production and to decrease cost are two important questions continually before the manufacturer. Since labor is the greatest cost of production, then, where machine tools are a considerable factor in the production, maximum output from the tool is a necessity. Tools that are limited in production because of a lack of power at the tool are a source of expense to the manufacturer. Power cost is low while labor cost is high. The well designed motor-driven machine of today shows the motor as one of the main elements of the tool, it having short-circuited much of the old mechanical drive, and not as a mere adjunct to the tool. Too little thought is given in many cases to the possibilities of the electric drive for machine tools.
