The Grinding Temperature of Alumina Ceramic in High Speed Deep Grinding (HSDG)

Abstract

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. The grinding zone temperature exhibits a reasonably linear relationship with the average energy flux, i.e. the higher the energy flux, the higher the corresponding grinding zone temperature will be.
