The Tribological Effects of Metal Removal Fluids Diluted with Purified Water Versus Hard Water
Metal Removal Fluids (MRFs) are generally diluted with water to form emulsions, dispersions, true
solutions or combinations thereof. The amount of water added to these solutions varies from 80% to 97%
by volume. Water is added to MRFs to improve cooling properties, insure proper dilution to reach the
point of application, and thus provide economic value to the end user in the manufacturing process.
