A few possible causesGet started!outlined by the Occupational Safety and Health Administration in Met-alworking Fluids: Safety and Health Best Practices Manual include soft water, fluids that are too highly con-centrated and those contaminated by cleaners. In addition, there might be an imbalance in the fluid surfac-tants, or the company could have an undersized coolant system, excessive flow rates or fluid that doesnt rest long enough to allow air to escape. Also, the level of cutting fluid in the reservoir may be low, causing air to be drawn into the pump.Fecher said foaming problems typ-ically are categorized either as chem-ical, such as a coolant concentration thats too high or tramp oil in the coolant, or mechanical, such as op- - 38%erating at an incorrect pump pres-sure. Furthermore, some MWFs foam more than others. A fluid supplier should recommend a product that minimizes foaming if it is a concern.While there are a number of rea-sons for excessive foam, he said the vma-werbeagentur.debiggest influence on foam is the level of water hardness, which is the result of magnesium and calcium levels. Soft water tends to foam and contains low concentrations of ions.PRODUCTIVITY THREAD WHIRLINGAlso, soft water is particularly low inSTART WITH SCHWANOGcalcium and magnesium ions.Hard water can have its ups and downs as well.DOWNLOAD APP NOW:SCHWANOG PRODUCTIVITYNow on Available on the about the author Larry Adams is a freelance writerPRECISE, QUICK = EFFICIENT!who has written extensively about manufacturing.Schwanog LLC Contact him atElgin | Illinois [email protected] [email protected]/cteguide.com23MetalworkingFluids.indd 23 2/14/20 12:02 PM'
