Modern high-performance drilling tools for quarry drilling rigs ball bits

This article analyzes the results of the study of modern drilling tools. In addition, the materials used in drilling tools were studied. The complexity of the manufacture of such a support consists in the need to melt the trunnion with a hard alloy, followed by grinding, manufacturing and pressing the support heel and sleeve from an anti-friction material, precision of the manufacture and assembly of the support. The quality of drilling operations depends on the timely and high-quality preparation of the rock mass for excavation and transportation, and, consequently, the technical and economic indicators of production in general.The main type of rock-breaking tools of modern heavy-duty rotary drilling machines are ball and drill bits.
