ABSTRACT:
A flat, elongate workpiece such as a knitting-machine needle, stamped from sheet metal with a transverse lug whose narrow faces require precise machining, is clamped in a workpiece holder with its lug centered on an axis about which the workpiece holder and an associated tool mounting are relatively rotatable. The tool mounting includes two symmetrically positioned supports, carrying respective power-driven shaping tools such as grinding wheels or millers, which are limitedly movable in a plane including the axis and are interconnected by a tension spring drawing them toward each other. An interposed cam disk, engaged by rollers mounted on these supports, determines the extent to which the two shaping tools can approach the axis in machining respective lug faces during a relative rotation of up to 180.degree..
