摘要：During the destruction of rocks by disc cutters the question of their operation without water cooling is arising. To implement this an approach to determining the temperature of the disk cutter is considered in the article. The calculations of heating of the disc cutter with various geometric parameters (diameter, sharpening angles, blunting edge radius) and geological conditions under different cutting conditions (cutting depth) are presented. The disc cutter temperature and comparison with a critical one is given. The results allow to increase wear resistance and thereby determine the modes of operation in which forced cooling of the cutting disc is not required.
