FIELD: machine engineering, namely apparatuses for balancing spindle assemblies having technological unbalance.
SUBSTANCE: apparatus includes correcting discs arranged in oil bath with possibility of rotation in chuck mounted in spindle and guarded by means of stationary jacket; mechanism for fixing correcting discs relative to spindle; device for braking correcting discs. Said device is in the form of case in which inserts of hydrodynamic support are mounted. In order to enlarge using range of apparatus, mutually opposite radial openings are formed in case and cylindrical studs with spherical ends rested upon inserts of hydrodynamic support are placed with gap into said opening. Other ends of studs rest through introduced roller upon circular race provided on inner surface of stationary guarding jacket of chuck.
EFFECT: enlarged using range.
