IF welding quality reamer in the application of the production process, carried out exploratory research

Welded to the quality of the IF reamer process of making the application, carried out exploratory research. With the corresponding jig, the frequency of the bit to the overall weld welding, greatly improve the welding efficiency. Stable welding quality, worthy of promotion use.
According twist drill into the object, and to design appropriate sintered formula, select the sintering process parameters and the gauge mode. And in strict  polycrystalline diamond  with the welding program, were welded using high frequency, medium frequency welding,  Polycrystalline diamond  welding flame welding three kinds of high-quality drill welding methods. Three kinds of welding methods have advantages and  Abrasive grinding wheel , three kinds of welding methods are able to meet the work requirements of PDC drill bit quality.
With the advances in manufacturing technology alloy drill, so that the composite sheet on the substrate directly sintered high a PDC drill bit manufacturing method possible.
