The machine tools are required speed-up and working with high accuracy. To achieve the two factors, our study have done improving the performance of sliding characteristics of slideway which has high stiffness, high damping capacity and easiness of installation of the machine tools used in processing system. The feature of our experimental apparatus is able to examine with a large-scale(100cm^2) test piece in large measuring range. We give the texture of the groove and the dimple shape on the sliding surface and examine lubrication properties. Characteristic length, pitch and depth were set from mm to ,u m as the parameter of the texture. The texture was processed by the sandblast method. Dimple texture has the low friction in mixed lubrication region and expanded the mixed lubrication region because we consider that the dimples played the role as the oil reservoir in this paper.
