METHOD FOR WORKING OUTER SPHERICAL SURFACES BY MEANS OF MULTIBALL TOOL Russian patent published in 2003 - IPC

FIELD: plastic metal working, namely working by surface plastic deforming of machine parts with increased demand to quality of surface layer of spherical surface. SUBSTANCE: method comprises steps of imparting to worked part and to deforming multiball tool motion along circle laid in plane shifted relative to center of worked spherical surface; additionally imparting to deforming tool rocking motion by angle ϕ relative to center of spherical surface. EFFECT: uniform mechanical properties of surface layer of material, elimination of overhardening in all zones of spherical surface of worked part, enhanced operational properties of working surface of part. 2 dwg, 1 ex
