What is "Soluble-Oil Cutting Fluid"?
Fluid in which oil is suspended in water. Since water is a superior heat removal agent, this fluid is primarily used when lubrication is desireable, but cooling is the key consideration. The ratio of oils and other additives to water varies with the application. For milling, the ratio of water to oil/additives runs 20:1 to 25:1. For sawing and other work, where a more confined tool/chip/workpiece condition is normal, a 10:1 ratio is used to improve lubricity. Additives include emulsifying agents that help keep the oil in suspension and substances that promote wetting, enhance lubricity, prevent chipwelding, and inhibit rusting. Also known as emulsified oil.
