Thread rolling machines as cold rolling is an advanced process without cutting, which can effectively improve the internal and surface quality of the work-piece. The radial compressive stress produced during processing can significantly improve the fatigue strength and torsional strength of the work-piece. It is an ideal process with high efficiency, energy saving and low consumption. With 10 years experiences in this industry, as trusted thread rolling machines factory in China, we have exported multi-function thread rolling machines over many countries such as Middle east, East Europe, East Asia, Africa and so on.
