THERMAL DAMAGE IN GRINDING

  In some grinding applications the use of an oil is impractical and a water based fluid must be chosen when this is the case other measures can be taken to reduce the likelihood of thermal damage The temperature of the grinding fluid for example has a pronounced influence on its heat removal capability Salmon 1979 has shown that as the temperature of the bulk fluid decreases the
