DEVICE FOR SURFACE PLASTIC DEFORMATION OF DEFECTIVE 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 defective spherical surfaces by surface plastic deformation. The device has an individual actuator with a spindle, on which are fitted a deforming element and a low voltage source of electrical current for supplying current to the deforming element and the work piece. The deforming element is made in form of a screwed coil spring, one end of which is made in form of a deforming ring for contact with the work piece, and the other end is wound on the spindle. The deforming ring is made with the provision for rotatory motion in a plane, displaced relative the centre or the spherical surface.

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