OPTIMUM SHARPENING ANGLE FOR DRILLING TOOLS

The article discusses a method for increasing the efficiency of rock cutting processes by mechanical means by optimizing the angles of inclination, sharpening of the drilling tool. Drilling tool fixtures and mechanisms used for drilling holes and wells. Drilling machines is a complex of drilling equipment or structures, units and devices intended for drilling holes and wells. The article investigates the influence of the geometry of the angle of inclination of the pressing (cutting) surface of the tool on penetration into the rock. Efficiency is determined by a decrease in the resistance to the penetration of tool blades into the rock. At present, the efficiency of penetration of the drilling tool is ensured by the rotational and shock-rotational forces of the drilling mechanism acting on the drilling tool.
