PROBLEM TO BE SOLVED: To produce a gear part having an internal tooth having a geometrically high precision. SOLUTION: In this fluidized forming method by which a work 26 of axially symmetry is fixed to the free end of a spinning mandrel 2 having a prescribed external profile, the spinning mandrel 2 is rotated together with the work 6, at least one piece of spinning rollers 34 is sent out, the work is formed as well as shaped to the external profile of the spinning mandrel 2, a spacer 14 of a deformable material is mounted apart at a prescribed from the free end on the spinning mandrel 2, the spacer 14 is shaped in forming a laying over region, subjecting to plastic deformation as well as material hardening, the spacer 14 remains further for forming of the work 26 of the spinning mandrel 2.
