The water driven spindle which has water hydrostatic bearings and the water driven mechanism has been developed for ultra-precision machining. In ultra-precision machining, if the deformation of the spindle is caused during the machine process, the deformation degrades the machined accuracy, accordingly. Water can be used as an effective cooling media for the water driven spindle because of the better thermal properties of water. It is considered that this improves the thermal stability of the spindle because of the large thermal conductivity and the specific heat of water. In this study, we will consider the thermal stability of the water driven spindle experimentally. As a first stage of the study, the change in the temperature of each parts of the spindle is measured experimentally during spindle rotation with various rotational speeds.
