Improving the Quality of the Technology of the Process When Preserving Tungsten Carbide Inset Cutter in the Cone

Determined that modern technology to ensure normal distribution sizes of holes in the roller cone bit for installation cutter pick under the false standard size of 14 mm create favorable conditions for selective grouping groups the size of holes and plug tungsten carbide inset cutter. In article proposed a method to establish rational parameters tensions in the design of connections “cone — tungsten carbide inset cutter” nine selective groups. This approach enables to provide constant average value of tension at 0.103 mm.

Improvement Technology Manufacturing Drill Bits With False Rock Cutting Rigging During the Design Process of Pressing Carbide Inserts in Milling

Favorable conditions are created under false carbide teeth for grouping selective groups of dimensions of holes and teeth if the conditions existing technology to ensure normal distribution of sizes of holes in the crown cutters. The proposed method allows to determine the optimal parameters tensions in the design of connection “tooth-rolling cutter” in selective groups.

Designing New Product Line of Cutters for Development of Functional-oriented Technology of Their Manufacturing

The aim of research is the improvement in quality indicators embedded rock cutting equipment of cutter drill bits. Research carried out as in a real production drilling bits and during modeling in CAD-system, integrated use of experimental laboratory, bench and field operational tests.
