Abstract: Method of obtaining hollow forgings by radial forging of solid blanks where generating AA of the surface of solid blank (1) or its edge is oriented longitudinal axis CC of the working surface of forging tool (3) and blank 1 is swaged in a radial direction by at least one pair of forging tools (3) first in one direction with its subsequent rotation around longitudinal axis OO and/or is moved along axis OO, is swaged in another radial direction at defromation rates approximately within 3-8% of the current cross-sectional dimensions of blank (1) with the result that the width of the contact area element is approximately within 0.121-0.124 of said current cross-sectional dimension of blank (1).

Abstract: Method of radial forging of blank where blank is set up in chuck head of a manipulator, swaged by at least two pairs of oppositely mounted forging tools while applying at the same time normal swaging forces created by said pairs of forging tools, and shearing force then is moved along longitudinal axis or turned around longitudinal axis while the operation of swaging of blank is accomplished simultaneously at its two portions and arranged in succession along its longitudinal axis, while shearing forces are applied at these portions in opposite directions.
