The skew rolling is new technology of producing various shafts, compared with common forging, casting and machining, the processes have many remarkable advantages. The productivity is as 3-10 times as that of conventional processes, the material consumption can be reduced by 20-35%, comprehensive mechanical properties of workpieces rolled by the processes increases about 30%, service life of the dies increases about 10 times, and there is no pound and low noice. The processes apply to produce commercial shafts and balls used in automobiles, tractors, electric motors. and other machines.
