As higher precision machining is required, reducing thermal defomation of a machine tool becomes more important. And in the 21st century, as it is also important to produce a product with care for protecting the earth, a producer must be careful on conservation of energy. Therefore, in previous reports, a self compulsory cooling for reducing thermal deformation was proposed. This method is the compulsory cooling using water evaporation, and thermal deformation of a machine tool is finally reduced. The countermeasure is very cheap and effective in order to reduce thermal deformation. In this report, a model of the self compulsory cooling using water evaporation was made for simulating phenomenon of its cooling and evaluated. Then, wind velocity is controlled by the model for reducing thermal deformation of a bench lathe. It is concluded from the results that (1) the suitable wind velocity for reducing thermal deformation of the bench lathe was calculated by this model. (2) This model could use effectively for controlling the self compulsory cooling.
