る。2. Description of the Related Art Conventionally, extreme pressure additives have been added to lubricating oils for metal working in order to impart lubricity under severe working conditions. Among the extreme pressure additives, chlorine-based extreme pressure additives are frequently used because of their excellent cutting performance improving effect and low cost. However, in recent years, when lubricating oils containing chlorine-based extreme pressure additives are used, there is a problem of environmental pollution due to generation of dioxin during waste oil incineration and corrosion and damage of incinerators due to chlorine gas. A lubricating oil that does not contain is desired. Lubricating oils containing no chlorine have the problem of lacking lubrication performance and cannot be applied particularly to difficult machining in cutting, but sulfur-based extreme pressure additives are promising alternatives to chlorine-based extreme pressure additives. In general, dialkyl polysulfide, sulfurized fatty oil and the like are used. With the progress of processing technology, lubricating oils with higher performance are desired.
