The present invention provides a dynamic balancing ring for a cutter
holder for balancing the cutter holder. The dynamic balancing ring
includes a circle, plural fixing elements and an adjusting element. The
plural fixing elements are used for fixing the circle on the cutter
holder, and after the center-of-gravity position of the cutter holder is
obtained by dynamic balance corrector, the adjusting element can be
installed at a position on the circle corresponding to the
center-of-gravity position, and through adjusting the adjusting element,
the dynamic balance of the cutter holder can be corrected. For using the
dynamic balancing ring for the cutter holder according to the present
invention, it is convenient that the dynamic balancing ring can be
directly installed on the cutter holder, which is needed to be corrected,
without additional processing.
