FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. Tube billet wall is subjected to plastic strain by flat working surface of spinning tool moving along rolling arc to make a fillet and a flat bottom with central bore. Note here that flat bottom is made together with drilling central bore by cutting tool secured perpendicular to spinning tool working surface plane at a distance from tube billet outer wall plastic strain start with due allowance for fillet length and central bore diameter.
EFFECT: higher efficiency.
