Temperature measurement in high efficiency deep grinding ...

01.09.2005  Temperature measurement in grinding presents a number of challenges particularly in High-Efficiency Deep Grinding (HEDG). High work-speeds require fast response and deep cuts require measurement over a large temperature field. High-speed fluid delivery creates problems for all types of temperature measurement. Electrical noise may require zero-shift filtering. Several techniques of temperature ...

THERMAL DAMAGE IN GRINDING

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 ...

Thermal Models of High Efficiency Deep Grinding and ...

Introduction High efficiency deep grinding (HEDG) is characterized by high wheel speed, high workspeed and large depth of cut, HEDG gives rise to very different grinding conditions in contrast to the conventional shallow grinding and creep-feed grinding [1-6]. For the calculation of grinding temperature, most thermal models developed up to now handle the conditions in which the heat

The Grinding Temperature of Alumina Ceramic in High

The grinding temperature in wheel-workpiece contact zone in HSDG of alumina ceramic was measured using the grindable K type thermocouple. Effects of the grinding conditions, including wheel velocity, feed rate and depth of cut, on the temperature were investigated. The results indicate that the grinding temperatures measured under different grinding conditions varied from 100 to 300 °C.
