T1101-2-5 Effect of surface texture on oil film thickness of slideway

Abstract

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 dimple shape on the sliding surface and examine lubrication properties. The texture was processed by the sandblast method. In this report, the eddy current displacement sensor was installed in the experimental apparatus and we experimented under oiling condition. As a result, we were able to measure the oil film thickness and we have understood that the oil film thickness depends on oiling rate.
