Our factory is a large-scale enterprise producing bending forming machinery. In the past, the surface roughness of the inner (?) 300~(?) 700mm cylinder was achieved by the last honing process, which was labor intensive and inefficient. To this end, we applied the rolling processing technology to design and manufacture an adjustable inner hole floating rolling tool, which has a good effect. The surface roughness R_α0.8 is processed, the quality of the product is guaranteed, and the efficiency is increased by 3 times.
