PURPOSE:To provide the titled novel lubricant giving high performance especially in heavy-duty cutting processing such as boring, gear cutting or gun drilling processing, containing alkali metal salt of inorganic acid such as silicic acid and chlorine-based high-pressure additive. CONSTITUTION:The objective lubricant containing (A) ca. 0.2-10wt% (pref. 1-5wt%) based on the component except the water contained in the final lubricant, of at least one kind of alkali metal salt of inorganic acid selected from silicic acid, boric acid and phosphoric acid, and (B) ca. 1-40 (pref. 5-20) wt% of a chlorine-based high-pressure additive (e.g. chlorinated paraffin, chlorinated fatty acid methyl ester). EFFECT:Outstanding in high-pressure capability, lubricity and rust-proofness; also easy to emulsify. |
