The perpendicular guideway mechanism is required high coupling characteristics and high precise slide motion of the slider. In this paper, the coupling characteristics (static and dynamic) of the grinding wheel head (slider) are considered by using perpendicular guideway of an actual surface grinding machine. In conventional type guideway, the slider to slide along the guideway, the gap must be provided between two opposite sliding surface. When the gap is wide, the slider performs undesirable motion in addition to the slide motion. Conversely, this gap is narrow, the sliding friction increases in the slideway. However, appropriate friction is achieved damping effect as the dynamic coupling stiffness. For these reasons, it is proposed that new type guideway satisfies the requirement. The new type is called composite bearing guideway mechanism (one side is slideway bearing and other side is hydrostatic bearing guideway). As the result, this paper is obtained to achieve high coupling characteristics from experimental and analytical results.
