Abstract
A fixture is disclosed for holding a tubular workpiece during the machining thereof. The fixture includes a base plate that is adapted to be placed over a mandrel that supports the workpiece. A pair of spaced apart blocks are slidably mounted on the base plate and each includes a plurality of roller means that depend downwardly therefrom. Guide means are provided for the blocks which are displaced towards the axis of the workpiece by means of a pair of opposed air cylinders so that the roller means engage the periphery of the workpiece and center the workpiece with respect to the axis of the mandrel. The workpiece may then be machined such as by forming external threads thereon.
