PCD tool processing diamond milling cutter [email protected]

Description of Diamond coated inserts PDC inserts
1.PDC cutters are sintered with selected diamond powder and tingsten carbide compact under high temperature and ultra high pressure.
2. The PDC cutters have high hardness, high abrasion resistance and high impact resistance.
3. PDC bttons bits can be widely used for oil and gas well drill bits, geological drill and mining drill bits. The PDC cutters can also be used as cutting tools with diamond for cutting, griding and polishing.
Application of PDC cutters:
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:
1.New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks
2.high strength, high hardness and high wearing property of diamond layer as well as good self-sharpening
3.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
4.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.

HOW PDC CUTTERS ARE MADE ?
Cutters are made using a combination of high heat and high pressure. Man made diamonds can be grown in 5-10 minutes. Because of this diamond content, a fixed cutter bit may also be known as a diamond drill bit.
High heat plus pressure creates a PDC (polycrystalline diamond compact) cutter.

Cutters are made from a carbide substrate and diamond grit. High heat of around 2800 degrees and high pressure of approximately 1,000,000 psi forms the compact. A cobalt alloy is also present and acts as a catalyst to the sintering process. The cobalt helps bond the carbide and diamond.
During the cooling process, the tungsten carbide shrinks at a rate of 2.5 times faster than the diamond. Controlling this stress, as with most aspects of drill bit design, is called Intellectual Property, and manufacturers rarely, if ever, share their secrets.
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 60000 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
