What is the CVD diamond

CVD synthetic diamond is an acronym for chemical vapor deposition diamond, pure diamond polycrystalline structure, no cutting surface, no metal binder. More SuperHard offers a full range of CVD diamond grinding, cutting, dressing, coating, thermal and wear part solution and service

Applications of CVD diamond

CVD diamond plate is used for semi-finishing, finishing, super finishing and continuous cutting of ultra precision cutting tools. In addition, the CVD diamond is also used for other high-tech applications (such as diamond dresser, wire drawing die, electronics, optical window, heat spreader and gem stone industry, etc).

How many types of cvd diamond plates

1. CVD diamond plates for cutting tools

Benefits of cvd diamond plates for cutting tools

- Because the concentration of atomic hydrogen produced by arc discharge is relatively high, the CVD tool blank processed by the DC arc plasma jet also has a higher thermal conductivity than the tool blank processed by other methods even at higher grown rate. This shows that CVD is obviously beneficial to heavy high-speed cutting operations.

- The CVD diamond tool is made with CVD diamond blanks without any binder, sharing the same surface smooth finish as the natural single crystal diamond.

- The working life of CVD diamond cutting tools are 100 times higher than that of hard alloy.

Applications of cvd plates: non ferrous materials, ceramic, abrasive composites, high silicon - content aluminum alloy, graphite and other difficult machining materials.

2. CVD diamond for optical windows

The high-quality CVD diamond has excellent optical performance, it has high optical transparency in х -RAY, UV, visible lightinfrared light, even up to the millimeter-wave.

Excellent transparency in the optical, high thermal conductivity, extraordinary high hardness and high fracture toughness, and very low thermal expansion coefficient make cvd diamond an ideal material for highly demanding optical window the broad band optical transparency

Applications of cvd diamond plates: for optical windows. Such as high power laser windows, high power micromave windows and durable windows, etc

3. CVD diamond blanks for dressing tool

Chemical vapor deposition(CVD) for dressing tools is made by laser cutting CVD diamond thin-film. CVD diamond blanks are suitable for various dresser tools,

- Single - point cvd dresser

- Multi - point cvd dresser,

- CVD rotary dresser,

- CVD diamond dressing roller

CVD diamond blanks produced by the high quality semitransparent polycrystalline diamond, with no binder phase, have excellent thermal stability and high thermal conductivity.

 The cvd diamond grade includes (standard grade and high quality grade) 

4. CVD diamond wire drawing die blank 

Wire drawing is a metal-working process relies on a combination of a die and/or a series of dies to pull or draw a wire to a chosen gauge and is utilized to reduce the cross section of a wire.

CVD diamond consist of a metal case and a nib made from monocrystalline diamond or polycrystallie diamond (PCD) or CVD diamond.

Applications of cvd diamond : wire drawing of stainless steel, tungsten, molybdenum, copper, aluminum and others alloy, etc
