Diamond Cutting Tool PDC Cutters PDC Inserts for PDC Drill Bits Stock 1308 1313 1608 1616 PCD drill bits
Diamond Cutting Tool PDC Cutters PDC Inserts for PDC Drill Bits Stock 1308 1313 1608 1616 PCD drill bits 1.A PDC consists of a polycrystalline diamond layer and a cemented carbide substrate. It is made by sintering fine diamond powder and cemented carbide substrate together at a high atmospheric pressure and temperature (about 60,000atms and 1,400-1,500℃). It is suitable for drill bits (PDC drill bits) working on various strata. Due to the complete D-D bondings among the diamond grains at the polycrystalline diamond layer, the diamond layer has high strength, hardness, and wear resistance and also shows excellent self-sharpening performance. 2. In its operation, a PDC drill bit crushes rocks by cutting and is more effective than a roller cone bit crushing rocks or an impregnated diamond bit ploughing and grinding rocks. The polycrystalline diamond layer and the cemented carbide substrate are combined in a tooth structure, thus consolidating the two layers and ensuring better impact resistance of the drill bit. 高 计上 |
