As a proactive measure to assist our users of Etna metalworking fluids we have created a library of Etna Tech Talks as reference documents. Listed below is a sampling of what is available. To preview any of the Etna Tech Talks, just click on the specific title in the table to get an overview of what that Tech Talk contains. Water Dilutable Metalworking Fluids Corrosion Control Heat removal is one of the most important functions of a metalworking fluid. Effective heat removal yields good tool life and dimensional accuracy of parts.
Water has greater capacity for removing heat than oil.
However, water alone in contact with freshly machined metal leads to corrosion. Thus, corrosion is a problem faced by every manufacturer of water diluted metalworking fluids. Top of Page Foam Control Foam generally is considered to be an undesirable property in a metalworking fluid. Since most metalworking fluids have good cleaning properties to help keep machines clean, they also foam when agitated. The quantity of foam that occurs, then, depends upon the chemical composition of a metalworking fluid product, the quality of the water used for mixing, and the degree of agitation in the system.
