44mm & 51mm Large Diameter PCD Blanks for Cutting Tools

Composition of PCD (Polycrystalline Diamond)
Polycrystalline Diamond (PCD) is a synthetic diamond product that is produced by sintering together selected diamond particles with a metal matrix using sophisticated technology. The diamond and matrix, when sintered together under high temperatures and pressures, creates a PCD tool blank that is high in uniform hardness and is abrasive resistant in all directions. This PCD diamond layer is then bonded to a tungsten carbide substrate, which provides strength and a brazable base to permit bonding to other metals.
Polycrystalline tipped tools are exceptionally resistant to wear compared to tungsten carbide or ceramic tools. In certain applications, PCD tool life can exceed carbide cutting tool life 50 to 100 times.
In certain applications, polycrystalline tipped tools have several advantages over natural diamond.
Shock Resistance
PCD is more shock resistant over natural diamond because of its random orientation structure of the diamond particles, and is backed by a carbide substrate.
PCD is more constant in wear. Again because of the random orientation of diamond particles. Natural diamond is a single crystal in nature and has soft and hard grains. Depending on the shape of the natural diamonds and the tool being manufactured, it is sometimes not practical to have the hardest grain on the cutting edge.
PCD is readily available in a large variety of shapes and sizes. Discs as large as 60 mm in diameter are now available. Natural diamond is limited to what is formed in nature. Diamond, even with only an 8 mm long cutting edge is extremely difficult to find and is very costly.
PCD is a conductor. This allows us to routinely produce complex form tools and grooving tools with our wire EDM machines. Such tools are impossible to produce in natural diamond.
PCD blank costs are considerably lower than the cost of natural diamond stones, and the availability of different shape PCD blanks reduce manufacturing cost significantly. The longer of a cutting edge required, the larger the savings of PCD over natural diamond due to the rarity of larger stones.
Natural diamond and PCD diamond compliment each other. Natural diamond is denser than its PCD counterpart and consequently can be polished to a keener cutting edge.
Natural diamond is best suited to produce very fine finishes and precise tolerances as required in the manufacturing of jewelry, plastic contact lens, computer memory discs, and aluminum camera parts. See natural diamond tools.
Polycrystalline diamond tooling can be used in a wide range of machining operations such as milling, grooving, turning, facing and boring. They are recommended for machining nonferrous metals and abrasive non metallics.
Diameter: 44mm,51mm
Grain size: 5 micron, 10 micron and 25 micron available
Total Thickness:1.6mm, 2.0mm and 3.2mm
It's recommendedfor cutting wood composites,non-ferrous materials and other highly abrasivematerials
