IMPROVEMENT OF THERMOPHYSICAL SITUATION IN CUTTING AREA FOR DRILLING AT THE ACCOUNT ENDOTERMIC OPPORTUNITIES OF NANOGLINIST MINERAL ADDITIVES TO OIL COILS
In the article, we show the aggravating thermo physical circumstances due to which the drilling process of hard-to-work materials, in contrast to turning, requires the use of oil lubricating-cooling technological (OLcT) with increased heat removal capacity. We proposed to increase the efficiency of the drilling process by introducing additives to oil additives with energyintensive endothermic properties that increase their heat removal capacity. As an endothermic additive to oil OLcT, we proposed to use nanoclay mineral-montmorillonite. We described thermo physical characteristics of montmorillonite, due to which it exhibits endothermic properties. It is shown the compatibility of the temperature range of the montmorillonite manifestation of the endothermic effect with the operating temperature of the OLcT in the cutting zone during drilling.
