FIELD: process engineering.
SUBSTANCE: invention relates to production tools,, particularly, screw plates, for example, for cutting tools made from hard alloy or steel billets. Heated billet is fed by push rod into shaping element that has feed and deforming sections. Deforming section consists of transitions the screw line number and inclination of which are selected experimentally proceeding from plate material elasticity.
EFFECT: higher efficiency and precision due to plastic deformation in one pass by 35-40°.
