PCD/PCBN cutter PCD cutting tools

Application of pcd/pcbn cutter:
PCD Diamond Drill Tips / Blanks are commonly used in many industries like automotive and woodworking to printing. PCD are synthetic diamond products that are used in nonferrous applications. We manufacture and supply PCD polycrystalline Dieblank & Cutting that

consist of a layer of manmade diamond crystals bonded to each other and to a cemented carbide substance. These are made from fine quality material, exact dimensions and sturdy construction.

The PCD cutting tool blanks are widely used for the machining of non-ferrous metals and alloys, such as aluminum, copper, aluminum / gray iron composites, as well as nonmetallic materials such as wood, chipboard, ceramics, plastic, rubber etc, where high abrasion

resistance and good surface finish are required. The products are available in 5um, 10 um and 25um.

And the application fields including aviation, the car industry, electronics, and the wood and stone industry, ranges in many different fields.

Features of pcd/pcbn cutters:
1. The hardness of PCD reaches 8000HV, which is 80 to 120 times that of tungsten carbide.
2. The thermal conductivity of PCD is 1.5 to 9 times that of tungsten carbide, and it is even higher than that of PCBN and copper. Its thermal conductivity is 700W/mK. The PCD blank can transfer heat fast.
3. The friction coefficient of PCD is only 0.1 to 0.3, while that of tungsten carbide is 0.4 to 1. The PCD cutting tool features small cutting force.
4. The heat expansion coefficient of PCD is 0.9×10-6 to 1.18×10-6, which is only one fifth that of tungsten carbide. The PCD cutting tool features small thermal deformation and high processing precision.
5. The affinity between the PCD cutting tool and the materials, including nonferrous metal and nonmetal materials, is small. The cuttings will not attach to the tool during processing.

1. Diamond polymer
2. With the high temperature and the ultrahigh pressure sintering
3. Made of Diamond and bonding agent
4. High heat resistance and high thermal stability

Description of pcd/pcbn cutters:
The PCD blank has the advantages of high hardness, high abrasive resistance, high thermal conductivity, low friction coefficient, low heat expansion coefficient, good strength and toughness. It can realize high speed cutting, hard material cutting and high precision processing. The PCD blank meets the requirement of environmental protection. The PCD blank is manufactured by world famous companies.

PCD/PCBN is made by high pressure high temperature sintering of cubic boron nitride with a binder pahase, and there are mainly tow groups of binders, namely metal binder and ceramic binder. CBN and diamond are very similar in crystal structure, chemical bond and lattice parameters, thus they perfotm quite similar hardness and strength,. In cutting applications, the wear resistance of PCD/PCBN cutting tools exceed 50 times that of tungsten carbide.

Advantage of pcd/pcbn cutters:

1. High hardness, abrasion resistance and impact resistance
2. High speed,high quality, good surface,long working life
3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl
4. Gauge pads have tungsten carbide inserts for maximum wear resistance.
5. The diamond layer with thickness over 1 mm increases abrsion resistence of PDC cutter.6. Made of polycrystalline diamond powder 
7. Sintered at high pressure and temperatur.
