• The mechanism of deformation in tube spinning is discussed on the basis of the observation of metal flow experimentally. The volume of the material built up in front of the roller, the critical reduction of the thickness of the tube and the elongation of the tube during the process are estimated quantitatively and then, it is proposed to introduce the parameters of deformation ξ and z_0 which are useful to explain the complex flow of the metal under the roller. From the accuracy of the diameter of the parts and the results of the measured working forces, optimum working conditions are shown which are useful for practical purposes in the industry. Besides, the process of two passes of a staggered roller is recommended from the results of comparison with one pass process of the roller.
