FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly to points designed to clamp and rotate thick-wall billet subjected to reduction at radial reducing machines. Proposed center comprises base with mounting seat made on its one end for attachment to radial reducing machine. Point is arranged on its opposite end. Said point has bore aligned with said mounting seat to center the billet. Inserted tenons are arranged on point face. Hardness of tenons equal 60 HRC while that of point is smaller than 50 HRC. Said tenons may be made up of rod with cone-, wedge- or pyramid-like working surface.
EFFECT: higher durability and improved reparability.
