Therefore, many enterprises and research institutes have begun to search and study the straightening of the ball screw.

Common cold-rolled lead screw blank is easy to deform when the diameter is thin after cold rolling forming, and the deformation of the small ball screw is generated in the processing engineering or after heat treatment, so that the deformation amount is small. The conventional equipment at the present stage is an electric straightener or a hydraulic straightener, the equipment is high in price, high in use and maintenance cost and slightly deformed, the two kinds of equipment are not enough to be used, and when the electric straightener or the hydraulic straightener is used, the straightening force is too large, trace straightening cannot be performed, and excessive straightening is often caused, so that secondary straightening is generated.
