Abstract
An assembly is disclosed for quick and easy mounting and removal of a circular die in coaxial surrounding relation to a machine spindle and which features a one-piece diametrically expandable sleeve concentrically interposed in wedged engagement between the spindle and die and a bi-directional displacement means which includes a jack plate in overlying stacked relation to the spindle for driving the sleeve in opposite axial directions toward and away from an operating position, the operating position of the sleeve being in wedged engagement between the spindle and die to remove clearances therebetween and to promote concentricity of the circular die.
