Polycrystalline CVD diamond

polycrystalline CVD (chemical vapour deposition) synthetic diamond products are manufactured by a chemical vapour deposition (CVD) process and are subject to tightly controlled growth conditions during manufacturing and equally stringent quality control procedures.
Polycrystalline CVD Diamond properties
1 Unsurpassed hardness
 
2 Extremely high thermal conductivity
 
(>1800 W/mK, five times that of copper)
 
3 Broad band optical transparency
 
4 Extremely chemically inert: Not affected by any acid or other chemicals
 
5 Graphitization only at very high temperatures (T > 700°C in an oxygen containing and 1500°C in an inert atmosphere)

CVD have two types ,which are standard Type and Tpremium type .

The CVD diamond produced by DC arc plasma jet system is light yellow-green and translucent.

It is the pure diamond with polycrystalline structure, without any metal and non-metallic agglomerant.

It has high transmission, high thermal conductivity and especially high abrasion resistance. It is the best replacement of natural diamond and synthetic diamond.

 
Premium Type:
Dressing Tools,including:Single-point diamond dressing tool,multipoint diamond dressing tool and diamond dressing rotary wheel.
Application Field:
For dressing: BFA and SIC grinding wheel, diamond grinding wheel and vitrified bond CBN grinding wheel.
For cutting: hard metal alloy ,copper and copper alloy, high concentration silicon aluminm alloy and oyher nonferrous metal, engineering plastics, complex material, ceram, glass and graphite.
Standard Type:
The CVD diamond produced by hot-filament is black and light tight. It is the pure diamond with polycrystalline structure, without any metal and non-metallic agglomerant and suitable for the occasion use where high wear resistance is required.

Dressing Tools, ncluding:  multipoint diamond dressing tool and diamond dressing rotary wheel.

Application Field:
For dressing: BFA and SIC grinding wheel, diamond grinding wheel and vitrified bond CBN grinding wheel.
For cutting: hard metal alloy ,copper and copper alloy, high concentration silicon aluminm alloy and oyher nonferrous metal, engineering plastics and  complex material.
