PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.
Alias: Polycrystalline Diamond Compact, PDC Inserts
Application: petroleum, oil field PDC bitsa
Specification
PDC cutters (Polycrystalline Diamond Composite) are consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure.
Application of PDC cutter
PDC cutters are widely used for petroleum and oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits. PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.
Advantages of PDC cutters
* New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks
* high strength, high hardness and high wearing property of diamond layer as well as good self-sharpening
* PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit
* The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and more impact resistance of the whole PDC.
Diamond Compacts of Tooth-shaped Structure Type
T-type: Diamond is combined with hard alloy in a latticed groove shape.
W-type: Diamond is combined with hard alloy in a wavy straight groove shape.
P-type: Diamond is combined with hard alloy in a plane shape.
O-type: Diamond is combined with hard alloy in a straight wide groove shape.
F-type: The combination surface of diamond and hard alloy has a radial groove-shaped structure.
B-type: The combination surface of diamond and hard alloy has a tooth-wrapped wavy straight groove structure.
Diamond Compacts of Chamfer Type
X-type: Both diamond layers and hard alloy matrixes are not chamfered.
U-type: Both diamond layers and hard alloy matrixes are chamfered.
Z-type: Diamond layers are not chamfered, but hard alloy matrixes are chamfered.
V-type: Diamond layers are chamfered, but hard alloy matrixes are not chamfered.
