Vibration-Free Machining of Pilgrim Mandrels

A support collar plate for the vibration-free holding of a workpiece, in particular a pilgrim mandrel, which is clamped at both ends and is to be processed between its ends by means of a grinding wheel, characterized in that

• the support collar plate is comprised of a base, arranged fixed in place with respect to the workpiece, and a clamp, which extends around the workpiece on at least two oppositely located sides,
• in which the workpiece can be clamped by a clamping force,
• wherein the clamp extends around the workpiece in such a way that it is possible to perform processing in the area of the clamp on the side facing the grinding wheel, and
• wherein the clamp is floatingly seated in at least one direction perpendicularly with respect to a longitudinal axis of the workpiece so that the clamp is self-centering with respect to the workpiece
• and, by means of the floatingly seated clamp, the workpiece is maintained independent of exterior forces which change the spatial position of the workpiece, and movements of the workpiece perpendicularly with respect to its longitudinal axis are damped by means of the mass inertia of the clamp.
