FIELD: metallurgy.
SUBSTANCE: by means of hydraulic forging there is shaped lug for nose section in the form of truncated cone. It is removed section of part of truncated cone top less basis. Then it is implemented rolling-off -flanging by roll of the rest part of truncated cone top less basis.
EFFECT: improving of details, power inputs saving.
