Brazing Diamond Bit Thermal Coupling Simulation Of Grinding Process

Analysis goal of this paper is brazing process at this stage is the rapid development of the manufacture of impregnated diamond bits, drill models taken after grinding stone flower micro drill test conditions, test data, and then to the material studied by means of grinding after working drill bit lip surface inlaid diamond particles as well as the basis of experimental data generated under brazing carbide chemical bonding layer above the grinding stone for diamond particles work process stress and temperature fields in thermal coupling mode based ANSYS / LSDYNA simulate different conditions to simulate the grinding process.According grinding experiment, the resulting material experimental data, based on previous research, for brazing impregnated diamond bits, the rock was single diamond drill micro unit and Rock Model A Simplified analysis, finite element simulation platform ANSYS / LSDYNA to simulate different thermal coupling method different diamond abrasive blade exposed, different grinding speed, depth under working conditions, work processes bit micro unit grinding granite materials, the system analyzes the several factors on diamond grain carbide chemical bonding layer, nickel-chromium matrix stress and temperature. There is no way to simulate binding carbide drill layers, namely between the diamond particles and nickel-chromium matrix analysis to study the impact of the action with the rock drill infinitesimal grinding process temperatures were discontinuous surface contact.Reproduction of the work process by software bit micro unit to obtain a diamond grinding process for crushing, scrap and other damage to the cause of exploration and get the work process of heat transfer among the law to clarify the chemical bonding layer- carbide present in the between the diamond particles and nickel-chromium matrix transfer process superiority in temperature.
