| Alkaline Having a pH of more than 7.0 which is the neutral point. Bacteria Feed on fatty components, corrosion inhibitors and other components of the emulsion. Grow in emulsions where the oxygen content is low. This produces sulfide gases and odors. Build-Up Edge (BUE) The pressure welding of the workpiece material to the top of the tool. Chips Small pieces of metal removed from a workpiece by a cutting tool. Concentrate Agents and additives that, when added to water, create a cutting fluid. Concentration The amount of a fluid's concentrate diluted in water. Cooling Reducing the amount of heat going to the tool and workpiece material in the cutting process. Corrosion Prevention Fluid used to protect parts and machinery from corrosion. Corrosion Protection Protection for the tools and machinery from rustinq and deterioration. Couplers Mutual solvents which make oil and soap compatible. Emulsion Oil droplets suspended and scattered throughout the water. EP Soluble Oils Extreme Pressure (EP) oils, contain sulfur and/or chlorine to improve cooling in machining operations. Extreme Pressure Additive Cutting fluid additive that chemically reacts with the workpiece material to minimize chip welding. Foaming Trapping of air bubbles in the cutting fluid. pH Value A way of measuring the acidity or alkalinity of a fluid. |
