Abstract：

In the paper, deformation patterns of the necking spinning with three rollers were studied. The experimental results indicate that the blank wall is thinned and axis length is extended. The thinning extent of wall thinness is in direct proportion to reduction in diameter. The number of spinning is larger, the thinning extent of wall thinness is greater under the same reduction in diameter condition.
