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

FIELD: technological processes.

SUBSTANCE: invention pertains to the technology of machine building, and particularly to processing spherical work pieces by plastic deformation. The work piece is rotated and transferred through longitudinal motion. A head with an individual actuator with a spindle is used, as well as a case with at least three deforming elements and a screwed coil spring for self-centralising of the deforming elements. The case is made with a tail and is fitted on a spindle through the screwed coil spring. One end of the screwed coil spring is wound on the tail of the case, and the other is wound on the spindle. The deforming elements are rotated and are made in form of cylindrical insert elements, which are in contact with the processed spherical surface.

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