Another trend in the development of PDC  drill bits is the study of new high performance PDC cutting teeth. The first is still to improve the cutting elements (polycrystalline Diamond composite sheet) wear resistance, mechanical properties, work Artistic performance and cutting performance. For many years, the gold of PDC cutting teeth The thickness of the stone is limited to 0.6mm (0.025 inches), which is because The researchers established the residual stress and diamond thickness of the cutting teeth. system. Residues in the PDC cutting teeth during the pressing process Stress, the size of which increases with the thickness of the diamond layer. Stress causes cracking, spalling, delamination of the diamond layer, which reduces The life of the  PDC   cutting teeth and the efficiency of the drill bit. To this end, polycrystalline gold The rock stone composite sheet shows the following development trend. 1. Improve the performance of the composite ...

1. Introduction of Exhibits Product- PCD Blank Polycrystalline diamond, abbreviated as PCD, normally called PCD blank, which is made by synthetic diamond micron powder at the high temperature and pressure sintering production environment. Features: Be used for drawing many different varieties of material, gold wire, copper wire, iron wire, steel wire, aluminum wire, etc; Based on the applications of wire drawing, the average grain sizes of diamond grain: 1 um, 3 um, 5um, 10 um, 25 um, 50um; Available for lots types of wire drawing operation, from rod-size to fine-size; Unsupported wire die blanks. Supported wire die blanks; Coblat-bond PCD blanks. Sillicon-bond PCD blanks; Can be used for wet and dry drawing applications; Good finish surface; Good wear resistance. 2. Introduction of Wanke The manufacturer with 28 years rich experience High-tech enterprise based diamond products Plant areas more than 124000 m2 8 standard workshops, 1 research ...

Everyone in the work and study, there will be a process, learning and work are also methods, so people in the daily life of the product will have its own working principle, PDC bit is the same, let's see how it works. The PDC bit is mainly based on the cutting teeth installed on the body of the bit. However, these cutting teeth also have two kinds of structure, which are the composite cutting teeth and the tooth column. The diamond composite cutting teeth are mainly formed by welding the composite sheets directly into the reserved grooves above the drill body, so it is usually used in the carcass bit. The tooth column cutting teeth are mainly welded to the tungsten carbide column, which will be embedded in the tooth column or in the teeth that are welded on the body of the bit. It is usually used in the steel bit, and some of them are used in the PDC bit of the matrix. DIAMONDWK is a highly professional manufacturer in PCD & PDC field. Our main products are P...
