Recently, the working fluid of hydraulic machines has been replaced from oil to water to reduce environmental problems. In order to solve the problems, the reduction of friction was tried using low viscosity oils and water. The serious problem of water or low viscous oils is their low loading capacity, even low viscosity, which causes the serious damage of the sliding surfaces. The application of surface texturing on the sliding surface is the promising method to reduce the friction. In this paper, we tired to introduce the surface texturing using EDM (electrical discharged machining), which made the isotropic random roughness. After removing the top peaks by polishing, several specimens with different surface height were prepared. When the friction for the specimens with surface texture were compared with that without the surface texture, the texturing could reduce the friction by 50 to 60%.
