In a machine tool such as a surface grinding machine or the like, a guide mechanism for the machine tool wherein one of a pair of opposed guideways is formed into a hydrodynamic guideway, whilst the other guideway is formed into a hydrostatic guideway, the hydrodynamic guideway is utilized as only one master guide, and on the other hand, the hydrostatic guideway is made to act in such that a moving body is pushed onto the hydrodynamic guideway with a constant pressure, so that this arrangement makes uniform the contact pressure distribution in the hydrodynamic guideway, thus the posture of the moving body is improved thereby making the same to perform precision linear motion. |
