This paper is a basic study to improve the positioning accuracy of the slide guide composed of a hardened plate made of alloy tool steel and sliders made of cast iron by reducing the friction coefficient in an ultra-lower sliding velocity region. Both sliding surfaces are finished as mirrors. The effects of lubricant additives such as amine salt of acid phosphate and sulfurized fat on reducing friction coefficients of the sliding surfaces were examined by both SRV tests and surface friction tests. Two kinds of lubricating oils of VG68 were used. One was a mineral oil and the other was a slide way lubricant on market. The optimum formulation ratios of the lubricant additives existed to reduce the friction coefficients in the ultra-lower sliding velocity region of a linear slide guide model. The amine salts of acid phosphate were effective in both sliding tests with the mineral oil and the slide way lubricant.
