FIELD: production processes.
SUBSTANCE: in compliance with the proposed method, the billion is roughed up to a required diametre and cut to separate its bottom part. The resulted billion with sinkhead is tapped down in vertical position to required diametre. The tapped down workpiece is turned over into horizontal position and forged to diametre. Note here that forging reduction making 2.5 to 3.0 is allowed for. The forged workpiece is cut to separate its sinkhead and the other end. Now, the workpiece is turned over into vertical position and tapped down to produce required height and diametre.
EFFECT: longer life of products produced from stock material thus produced.
