Grinding has always been a high energy expenditure process, which generally produce massive grinding heat and possibly produce thermal damage in workpiece ground surface. Therefore, a good understanding of grinding temperature characteristics is important to lower the thermal effect on the workpiece quality. However, the grinding temperature characteristic differs when grinding of different materials, especially for those hard-to-machine materials (eg. Titanium alloys and ceramics). Therefore, this paper is devoted to investigate different grinding temperature characteristics for metallic materials and brittle materials. In order to detect the grinding temperature, a grindable thermocouple technique with NI-DAQ device is adopted in diamond wheel grinding of ceramics and CBN grinding of Titanium alloys. The results show that the temperature characteristics for ceramics is totally different with Titanium alloys. When the grinding wheel speed increases, the grinding temperature increases all the way when grinding of Titanium alloys. However, there is a temperature turning point for grinding of ceramics. When the wheel speed surpasses the turning point, the grinding temperature goes down and closes at a relatively low temperature.
