摘要：
This paper reviews existing studies and investigates thermal operational regimes of diamond bit during drilling operations. The operating temperature of the diamond core drill is studied under bench condition and an optimal thermal range are presented. Based on this study, it was noted that glazing of diamond tools is observed at temperatures less than 327 degrees C, and normal wear of diamond tools is observed at temperatures within the range of 327-660 degrees C. Burning-in of diamond cores is accompanied by heating the matrix to temperatures above 800 degrees C.
