Thermal Analysis of Grinding - ScienceDirect

For High Efficiency Deep Grinding (HEDG) using CBN wheels with large depths of cut and fast workspeeds, preheated material ahead of the grinding zone is removed together with the chips, thereby lowering the temperature on the finished surface. Analytical models have been developed which take all of these effects into account.

THERMAL DAMAGE IN GRINDING

Feb 25, 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 ...
