Abstract: A contouring head includes a sleeve and coaxially mounted spindle connected by means of a yoke to a slide mounted by first and second sets of roller bearings to and between a slide track and a pair of keeper plates which hold the slide to the slide plate and within a slide track formed therein. A yoke interconnects the spindle to the slide to convert axial motion of the spindle into radial motion of the slide. A tool mount in the form of a pot is connected to the slide to control the radial position of a single edged cutting tool. A cover is mounted on the keeper plates and slide plate.

Abstract: An adapter for holding a workpiece to be machined in an accurately located axial position can include a main sleeve having an interior wall defining a passage extending therethrough with at least one inner surface angled inwardly toward a centerline of the passage, a workpiece locator engageable within the passage and supporting a positive axial location stop, an axially and radially moveable collet interposed between the main sleeve and a workpiece to be processed, and a rotatable sleeve engageable with the collet for accurately locating the workpiece to be processed by radially grasping the workpiece to be processed and axially moving the workpiece into engagement with the positive axial location stop.
