METHOD OF BURNISHING DISCS |
| 摘要 |
FIELD: processing engineering.SUBSTANCE: invention relates to metal forming and may be used for production of gas turbine engine discs. Disc cylindrical billet is revolved to displace inclined rolls radially over the billet, said rolls making a preset pass. Rolls are displaced from billet edges to its axis to create contraction strain at all stages of forming.EFFECT: development of contraction strain to eliminate pores, cracks and fractures.2 dwg |
