Abstract: Shaft part rolling technology is an advanced metal-forming technology. Since there are many advantages, such as high forming precision, good product quality, no pollution in production, low cost, that the advanced technology has been used in industrial production, and many research and development activities have been conducted in the world. The latest work in this field in our country, including part rolling theory research, products development, technology promotion and industrialization, die/mould design and manufacturing, equipment design and development are introduced. It is pointed out that our shaft rolling technology is in the advanced level in general in the world, and in leading position in some respects. Although our part rolling technology has been widely used in industry, but capacity of rolled parts is only about 1/10 by weight, so the technology has enormous market to be developed.

Key words: Cross wedge rolling, Part rolling technology, Skew rolling
