Fluid composition for metal working and its use in machining of compacted graphite iron

摘要

A composition and method for reducing tool wear during iron machining comprising applying a composition comprising water; a lubricant ester; and a sulfur-containing lubricant additive. In some embodiments, the lubricant ester or combination of lubricant esters is present in an amount of about 1% to about 50% by weight, a polyol ester; an ester based on glycerose; and / or 2,2 Dimethyl-1,3-propanediol, 2-propanol, 1,1,1, tris (hydroxymethyl) propane, 2-hydroxy-1,3-propanediol, 2,2-bis (hydroxymethyl) -1,3 -Propanediols and esters selected from those of C12-C18 fatty acid esters of 1,2,3-propanetriol may be included.
