FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to production of washers. Billet is deformed via pulling by taper slugger punch in radius or taper cavity of die. Then bore is punched to trim spherical or taper form. Now, shape is cut.
EFFECT: expanded performances.
