FIELD: manufacturing technology.
SUBSTANCE: invention relates to the solid-rolled strong frames manufacturing from the deformable alloys. Performing the workpieces-washers casting by the centrifugal casting method under the inert gas atmosphere by means of the melt feeding into the rotating mold and the workpieces-washers rolling. After the workpieces-washers casting, they are turned, and heated in the furnace, performing their shrinkage in height by means of the hydraulic press and then enabling the workpieces-washers rolling on the radial-axial annular rolling mill. Workpieces-washers turning is performed on the turning-and-boring machine with the tolerance, depending on the material shrinkage, foundry defects occurrence depths and the workpieces-washers wall thickness. On the workpieces-washers outer surface allowances for the turning are set less than on the inner side.
EFFECT: as a result, the part production is accelerated, energy costs are reduced and the frames reliability is increased.
