Natural ND Tool

As a natural diamond pull vine peak spectrum, has the following characteristics:
(A) is displayed at the 1332 Rush existence diamond.
(2) wave amplitude (FWHM) of 4.1cm-1
Displayed as pure diamond. ND is the hardest known mineral substances, mainly for the preparation of turning tools. Fine grinding of natural diamond tool edge radius

of up to 0.01 ~ 0.002μm. Where natural single crystal diamond (Single Crystalline

Diamond, SCD) cutting edge parts by high magnification 1500x still observed blade smooth. Ra SCD when turning aluminum pistons reach 4μm, and in the same conditions

using PCD cutting tools machining time of the surface roughness Ra of 15 ~ 50μm.

So the use of SCD tool with precision lathes for precision and ultra-precision machining, get the mirror surface.
PCD PCD tool
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.
Artificial PDC cutter
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. The use of synthetic polycrystalline diamond composite films that preparation tools, they can make with chipbreaker indexable inserts and

complexity of the geometry of three-dimensional surface milling
