Abstract：

With the rapid development of aerospace technology, the processing requirements of large parts are moving up, and the advantages of spinning technology to form the thin-walled rotary parts are more obvious. Consequently, the demands of large-scale spinning equipment become more and more urgent. The technical difficulties in the development of large NC spinning machine were analyzed in detail and the corresponding solutions were given. By the NC power spinning machine developed in the project, the diameter of formed parts can reach Φ2600 mm, the spindle speed is among 20-100 r·min-1 and the diameter of rotary worktable is up to Φ2800 mm. The test results show that the wall thickness difference of product formed is only (3±0.06)mm, and the various technical indexes of machine reaches or exceeds the international advanced levels.
