THERMAL DAMAGE IN GRINDING - ABRASIVE ENGINEERING

25/02/2003· 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 amount of heat removal and the power flux at bum increase (see fig. 7a and 7b). It is apparent from figure 7 that by reducing the fluid temperature from 40° to 20°C, the critical power flux could be ...
