DEVICE FOR BORE FLARING WITH CONTINUOUS BALL ROLLING Russian patent published in 2012 - IPC B24B39/02 

Abstract RU 2452608 C1

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for hardening of bores. Billet is revolved. Proposed device comprises mandrel with deforming elements, that is, balls arranged in screw groove and retained by plates. Screw channel allow deforming elements to be fed in lengthwise and crosswise directions. Groove start and end are communicated for removal and circulation of balls. Channel has two curved radial branches made from tubes, and straight branch located at center of mandrel axial line.

EFFECT: expanded processing performances, higher quality and efficiency.
