For thermal analysis of the grinding phenomenon, it is necessary to measure the temperature of a microscopic area in a very short time. A new infrared radiation thermometer using optical fiber was developed for determining the response time and the measuring area. The minimum response time was 3μs and the diameter of the measuring area was limited to just 110μm. Consequently, this thermometer was capable of measuring the exact grinding temperature which correlated with calibration curves of S45C and the grinding wheel (WA80JV). If the heat source area is larger than the measurable area, the obtained value directly indicates the temperature of the grinding wheel. In the case of an area smaller than the measurable area, modification using an equation including the distance and the area of heat is necessary.
