IN TRODUC T ION TO C V D DIAMOND Element Six is the world leader in the synthesis of diamond by chemical vapour deposition, CVD. The company has more than 30 years’ experience in this technology, and is the largest manufacturer of CVD diamond in the world. Element Six has a dedicated research and development facility committed to further improvement of CVD processes. C V D DI A MOND SY N T HE S I S At Element Six, a microwave plasma enhanced CVD process is the main diamond synthesis route that has been developed and refined. The process relies on decomposing carbon containing gas molecules,...

C V D FOR DRES SING APPLICATIONS C V D DI A MOND PR OPER T IE S Polycrystalline CVD diamond is chemically inert, has outstanding thermal conductivity, coupled with excellent wear and thermal oxidation resistance. For mechanical applications within the dressing and cutting tool sector, the key properties are: Within this family are CVDRESS CDD and CDM. CVDRESS CDD is a premium free-standing CVD diamond grade specifically designed for dressing and truing of grinding wheels. CDM is a grade suitable for rotary dressing applications. These products are normally supplied as rectangular logs in...

With outstanding thermal properties and very high thermal oxidation resistance CVDRESS CDD & CVDRESS CDM are ideal for secure mounting when using traditional non-ferrous metal sintering. Alternatively, dressers can be brazed onto a dresser body using an active braze alloy in a non-oxidising environment. Industry standard grinding techniques can be used to shape dressers in-situ to make cone, chisel and radiused shapes. CVDRESS (DRESSING TOOLS) CDD CDD L500808NP is a CDD grade ‘log’, 5mm in length, 0.8mm wide, 0.8mm thickness and having an unprocessed surface finish CDD T CDD R2608-360 is a...

C V D FOR CU T T ING TOOL & W E AR APPLICAT IONS CVDITE is generally recommended for machining non-ferrous materials where high abrasion resistance is required. CVDITE has high thermal stability and more wear resistance than PCD. C V DI T E Especially developed for cutting tool applications, CVDITE has been engineered to complement PCD and Monocrystal materials for defined edge tooling and is available as CVDITE CDE or CVDITE CDM. –– Laminated flooring, CVDITE CDE is an electrically conducting grade for cutting tools where the customers use electrical discharge machining (EDM) or electrical...

Synthesised as flat plates, CVDITE is processed to the exacting requirements and high standards of the diamond toolmaking industry. The product range covers tool blanks in various formats, shapes and sizes for the tipping of cutting tools and wear parts using typical tool fabrication techniques developed for natural diamond and Monocrystal diamond. Products are normally prepared with one fine lapped surface, which is preferred for bonding. Brazing to tungsten carbide substrates can be carried out in a vacuum furnace or reducing gas atmosphere, using high temperature active braze alloys. The...

GIVING TOOLMAKERS GREATER OPTIONS FOR T HEIR T OOLING SOLU TIONS The CVD range of products developed by Element Six for wheel dressing and cutting tool applications gives the toolmaker greater options for their tooling solutions. The overall benefits offered by CVD diamond add up to high abrasion resistance that suits all types of dressing and cutting applications, combined with high purity, high thermal conductivity and good thermal stability.
