Synthetic polycrystalline diamond compact (PDC) cutter

Polycrystalline diamond (PCD) cutting tools
PCD is a high temperature high pressure conditions by cobalt and other metal-bonded to synthetic diamond powder sintered polycrystalline material gathered, also known

as sintered diamond. Overall sintered polycrystalline diamond cutter cutter for milling, PCD grain was disordered arrangement state, subordinate to the

Gay, uniform hardness, graphitization temperature is 550 ℃. Tool has high hardness, high thermal conductivity, low thermal expansion coefficient, high elastic modulus

and a low coefficient of friction. They are very sharp and so on.
In order to improve the toughness of PCD inserts and weldability, often made of PCD and carbide cutter body synthetic polycrystalline diamond composite blade (PDc).

The surface of the cemented carbide substrate being suppressed 0.5 ~ 1mm thick layer of sintered PCD. The flexural strength of the composite blade with carbide

Consistent hardness close to PCD, PCD can replace the use. PCD and synthetic polycrystalline diamond compact (PDC) cutter sharp edge and workpiece surface quality than

ND. While its workability is poor, the grinding ratio is small, it is difficult based on geometric head

Like arbitrary shape. Current use of synthetic polycrystalline diamond compact Preparation Tool only, still can not be manufactured with chipbreaker indexable inserts

and complex three-dimensional
