Mining PDC Cutters

PDC Cutter Geology Industry U-shaped PDC cutter introduction The combination interface between polycrystalline diamond layer and hard alloy matrix of u-type PDC cutter adopts the combined non-planar binding structure. Pdc cutter Features: the outer ring is not a step structure, but a circular structure with oblique dimension. The structure can guarantee the normal shrinkage of diamond powder during ultra-high pressure sintering and minimize the residual stress caused by interface structure. The circular area at the center of the interface consists of a row of corrugated grooves. A single trapezoid groove is formed. The width and depth of a single trapezoid groove are greater than the rows of corrugated teeth. The meshing force between PCD layer and hard alloy matrix was increased. PDC Cutter for oil Industry The diamond composite is composed of a layer of polycrystalline diamond and a hard alloy matrix. Oil pdc cutter is will micro diamond powder and cemented carbide substrate and super high pressure high temperature (about * atmospheres, 1400 - a - 1500 ℃) under the condition of sintering, made of. Suitable for drilling in various layers of king kong composite chip bit (PDC bit). The diamond grains in the polycrystalline diamond layer have complete d-d bond bonding, which makes the diamond layer have high strength, high hardness and high abrasion resistance, as well as good self-sharpening. The rock is broken by shearing action, which is more effective than the crushing rock of the cone bit or the plough cutting and grinding rock of the diamond impregnated bit. The combination of polycrystalline diamond layer and hard alloy matrix is in the form of tooth structure, which makes the bond between the two layers more solid and ensures the drill bit to be more resistant to impact. Oil pdc cutter features 1. The leading position of pdc cutter quality stability is a prominent feature of HMR products, pdc cutter has been unanimously recognized by custo....
