METHOD OF PROCESSING DEFECTIVE SPHERICAL SURFACES BY 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 defective spherical surfaces by surface plastic deformation. There is rotatory movement of the work piece and the deforming instrument. The deforming instrument is mounted on a spindle of a device with individual actuation and made in form of a screwed coil spring. One end of the screwed coil spring is made in form of deforming ring for contact with the work piece, and the other end is wound on the above mentioned spindle. Electrical current is supplied to the deforming instrument and the processed work piece from a low voltage source and a static load is applied to the deforming ring. Rotatory motion of the deforming instrument is applied under the condition that, the deforming ring is rotated in a plane, displaced relative the centre of the spherical surface.

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