ABSTRACT:
A workpiece is clamped to a machine table while being machined, but a cantilevered portion of the workpiece is subject to vibrations. The cap of a vibration damping unit is supported on the machine base and spring-loaded upwardly against the workpiece. A support spring acting on a seat forces a damping element against the cap which, in turn, is impressed against the cantilevered workpiece. Vibrations are suppressed by horizontal shearing motion of the ring damping element. The entire damping assembly comprising the cap, ring damping element, seat and spring are retracted from the workpiece by means of a central rod connected to a manually actuated toggle clamp.
