Abstract：

It was studied systematically the oil filled and pressured spinning of copper inner spiral fin tube. Especially the conditions of generating dynamic oil film were analysed during oil filled and pressured spinning, and then mathematical model was constructed. The theoretical and experimental results show that the effects of hydrodynamic lubrication raise with the increase of spinning speed, oil viscosity and oil pressure, but the drawing load and surface roughness decrease.
