The serial studies aim tp reveal the torsional damping of the joint of machine tool structure, and the present paper discusses, in particular, the case when the contact surfaces are in adhension. For this purpose, the damping of the coupling model composed of a disc and a cylindrical pipe is obtained theoretically and experimentally for the case when their contact surfaces stick together by an axial pre-load. The damping is analyzed with regard to the resonant modal shape of the cylindrical pipe, assuming it coincides with the material damping of the cylindrical pipe. On the other hand, the dampings which were obtained experimentally could qualitatively explain the theory, hence it is concluded that the torsional damping of the structure which possesses the sticked contact surfaces may be estimated from only the material damping of the structure and the effect of the sticked contact surface could be ignored.
