404 Influence of texturing on tribology characteristics of slideways

This paper describes the frictional property in conducting the texture on the sliding surface for the purpose of improving the tribology property of slideway in machine tool. The dimple type texture, groove type texture and scraped texture are evaluated the friction coefficient by the test using test piece which has approximately practical dimension. On the dimension of the texture, the experiment was carried out from the order of micrometer to millimeter. We clarified that the texture mainly affects the friction coefficient of mixed lubrication regime. The texture of the parallel groove expanded the hydrodynamic lubrication regime, and the dimple of the millimeter size expanded mixed lubrication regime.
