DEVICE FOR VIBRATION EXPANSION OF HOLES Russian patent published in 2012 - IPC B24B39/02

Abstract RU 2441742 C2

FIELD: machine building.

SUBSTANCE: invention refers to vibration finishing and strengthening treatment of work. Invention includes body with deforming elements. The body includes operating cylinders with rod pistons which can move up-and-down. Deforming elements are made with sphere operating surface and fixed at the outer rod ends. The body can be rotated around axis coinciding the work axis and off-centered to the value of eccentricity in respect to own longwise body rotation axis.

EFFECT: increased treatment effectiveness, increased stability of the deformation elements, and easy deformation of microdefects of work surfaces.
