DEVICE FOR SURFACE PLASTIC DEFORMATION PROCESSING OF SPHERICAL SURFACES Russian patent published in 2008 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: invention pertains to the technology of machine building, and particularly to processing work pieces by surface plastic deformation. The device has a case in the form of a holder with a central opening and a deforming instrument. The deforming instrument is made in form of at least three bushes with an inner working surface: at least one of the first bush, at least one middle bush and the last bush. The indicated bushes are pressed onto the central opening of the holder and have a longitudinal groove for free passage of the neck of the work piece. The inner working of the first and middle bushes is made in form of a splined surface. The splined surface of the middle bush is displaced in the peripheral direction on one spline relative the splined surface of the first bush. The inner working surface of the last bush is in form of a smooth cylindrical surface.

EFFECT: high quality and accuracy of processing spherical work pieces by surface plastic deformation.
