Shape and structure analysis of polycrystalline diamond composite bits
Dec 10, 2017

The external and main structure of polycrystalline diamond composite bit is mainly composed of bit body, cutting teeth, hydraulic system, chip removal trough and diameter tooth.

There are two basic types of polycrystalline diamond composite bits: steel-body bit and bit. Steel body bit completely composed of mechanical processing, first will be the whole piece of alloy steel billet machining into bit body, and then cutting pieces of welding on the connecting column, finally will connect the pressure into the drill in the drill hole in advance (hole not drilled through), to ensure its processing quality. Tire body bit and polycrystalline diamond compact bit manufacturing methods are similar, tire body bit body adopts the pigeon carbide powder, pigeon carbide powder and proofing material sintering,, PDC cutting pieces Always with a elongation of substrate welded to the drill bit, it has the best gauge (with natural diamond) ability to gauge diameter surface using day Natural diamond or diamond impregnated gauge block effect is strong, has the strong ability to resist erosion, no connection column, therefore the phenomenon of won't appear the connection string, but complicated manufacturing process, processing is not easy to control.
