Soluble Oils are the preferred choice for grinding and machining operations where cooling is the utmost importance. Soluble oils are also efficient and economical and will mix with hot or cold water. typically, gauge soluble oils are diluted in water ratios ranging from 1:1 to 1:20 depending on the application. For example, the richer emulsions are used for the more difficult operations, where the intermediate mixtures are used for free-machining operations, and the lean mixtures are used for operations such as grinding, where massive cooling is required.
