    Abstract: PURPOSE:To prevent deterioration in performance when a sliding surface lubricating agent is mixed with a lubricating agent for machining by using a lubricating agent consisting of a mineral oil or synthetic oil, an extreme pressure agent, and an emulsifying agent each having a specified wt%, and having a coefficient of dynamic friction with less than a specified value, for a sliding surface, and a diluted liquid of said lubricating agent for a machining portion. CONSTITUTION:A lubricating oil consisting of a 10-90wt% mineral oil or synthetic oil with a 1.5-250cst of viscosity at 40 deg.C, a 0-30wt% extreme pressure agent such as a mixture, etc. of a sulfide oil and a phosphate ester, and a 10-60wt% emulsifying agent such as an sliphatic soap, etc., and having a coefficient of dynamic friction of less than 0.2, is used for the sliding surface of a machine tool, and a diluted liquid of this lubricating agent is used for a metal machining portion. In this case, the use of a lubricating agent having a coefficient of dynamic friction of 0.2 or more may cause a stick slip, reducing machining accuracy. Thus, since both functions as a sliding surface lubricating agent and as a metal machining lubricating agent are fulfilled by the same types of lubricating agents, neither deterioration in metal machining performance, nor reduction in the life of lubricating agent takes place even if a lubricating agent used for the sliding surface of a machine tool may be mixed into one in the metal machining portion.
