METHOD FOR STRENGTHENING OF SPHERICAL SURFACES Russian patent published in 2009 - IPC B24B39/04 

FIELD: technological processes; tool.

SUBSTANCE: provide rotary motion to device that comprises body with deforming elements available in it, striker and wave guide, to which periodical pulse load is applied. Rotary motion is imparted to processed stock. Deforming elements embrace processed stock and are arranged in the form of disk springs in amount that equals to even number. Disk springs are installed in bushing with collar installed in body. Disk springs have solid flat peripheral end surface and conic surface with incline angle to central axis having radial slots and central hole. Disk springs are assembled in packet with location of radial slots in staggered order relative to each other. Packet of disk springs is installed between bushing collar and wave guide.

EFFECT: technological resources are expanded, efficiency is increased, and prime cost is reduced.
