Tooling materials science| Zusammenfassung: | The purpose of the work, the results of which are reflected in this article, was to compare the granulometric composition and type of particles of rock cuttings with the parameters of the cutting ability of the working surface of a diamond rock cutting tool, which characterize the efficiency of its work at a constant ROP with different rates of destruction. Drilling with diamond impregnated bits and turning of the granite rock of the Korostyshevskoye field of the X category of drillability by the cutters based on diamond composite materials of various compositions were carried out for reaching this goal. Sludge samples were taken and an analysis of its granulometric composition was carried out using a modern analyzer model Microtrac Sync 3000.
Comparison of the degree of wear of the composite samples according to the data of the analysis of the granulometric composition of the cuttings showed that the less the degree of wear of the cutting edge of the rock-breaking element, the larger in size the cuttings are formed. Under the same test conditions, this indicates a more efficient use of the energy supplied to the bottom, which goes to a greater extent for the destruction of the rock, and to a lesser extent for friction and wear. The results obtained make it possible to clarify the nature of the influence of the ratio of the rotational speed and axial load on the energy consumption of rock destruction, as well as on the change in the fractional composition of the sludge particles formed during this process. |
