Abstract
An adjustable support liner for securely holding a workpiece centered in a machine tool that includes an elongated sleeve having a plurality of clamping units mounted therein capable of holding the work centered in the machine in an undistorted posture. Each clamping unit contains a ring-like body for encompassing the work that is formed of two hinged sections. Each section, in turn, has an axially extended jaw member depending outwardly therefrom and means to rotate the jaws between a fully opened and a fully closed position whereby a symmetrical centering pressure can be continually applied by the jaws over the entire working range of the apparatus.
