Abstract

Due to the special sensitivity of diamonds to the temperature factor, compliance with the normal thermal regime of diamond bits during drilling is one of the main conditions for their efficient operation. The normal thermal regime should be considered to be such a thermal regime at which the diamond heating temperature does not reach the value causing their oxidation, graphitization or deformation due to temperature stresses.
