ABSTRACT:
For machining male or female screws, especially of considerably large size diameter, variable pitch or tapered, as desired, a machining center is used which is composed of a work table mounting the work fixedly thereon, and a rotatable machining spindle exchangeably fitted with a thread-cutting tool. Axial feed and rotational speed of the spindle are driven by respective drive motors. In addition, the work table is fed bilaterally on a plane perpendicular to the axis of the spindle by respective feed motors. All these four motors are controlled synchronously by respective controllers which are subjected to control by a single parent numerical controller.
