CVD Diamond (Polycrystalline)
What is CVD Diamond?
CVD (Chemical Vapour Deposition) is the process by which CVD Diamond material is produced. CVD Diamond is grown either on the surface of a material as a coating or as a freestanding thick film wafer. These two types are often referred to as thin film or thick film diamond. The types of diamond produced also vary in type and quality depending on their use. CVD Diamond has no binder which is why this diamond has such a superior performance in tool life over PCD for example.
With diamond being unique in hardness and thermal conductivity, the development of CVD Diamond has opened up new uses within new industries.
CVD Diamond Types
We offer a full line of CVD Diamond covering milling, grinding, cutting, thermal and wear-part applications as follows:
- indab-CVD Dresser Grade
- indab-CVD Cutting Grade
- indab-CVD Coatings
- indab-CVD Thermal Grade
CVD Diamond for Dressing & Grinding
We offer three main types of CVD Diamond that are used in a variety of stationery dressing tools and rotary dressers.
Supplied in a variety of dimensions the IAS1 quality is our most popular Dresser Grade CVD Diamond ideally suited to rotary dressers but also used in stationery diamond dressing tools where the bond is optimised for the material. This material offers a good lifetime and wear resistance.
Available up to 2.2mm thick
Surface finish can be anywhere between ‘as grown’ to ‘a mirror polish’ if required
Each of our qualities are available with different surface finishes. Material can be delivered with the top surface left rough as it is when grown, or with a partial surface 30-50% / 50-70% ground surface (removing the high points), 100% lapped or polished.
CVD Diamond for Cutting, Milling & Turning
Especially grown and prepared for use in cutting/turning and milling operations, our cutting Grade of CVD Diamond if used correctly can outperform a traditional PCD tool by 2 to 3 times.
The IACT CVD Diamond Cutting Grade is the diamond layer only ready for you to vacuum braze to the tool body. This diamond is available in thicknesses between of 0.5mm (500µ) and 1.0mm (1000µ) with a polished surface. Other thicknesses are available upon request.
We have three cutting grades available for different applications. IACT-S, IACT-T and IACT-U. Contact us for more information.
Pre-cut segments are available in triangular, square and rectangular segments from our standard list of dimensions or cut to your specification if required.
If you do not have the ability to vacuum braze, please contact us as we may be able to offer a pre-brazed option for you depending on your specific requirements.
CVD Diamond Coating – IACoat
IACoat is a CVD diamond coating applied to approved grades of carbide tooling such as end mills, drills or even inserts. With so many new materials being developed and used in aerospace and other industries, the benefits of CVD are becoming widely realised. With improved cutting performance, longer tool-life before deterioration of tolerances, and less down time, they are worth some consideration.
The type of coating required will have to be established once application details are known to us. Finished tools can also be supplied to your specification.
CVD Diamond Heat Spreaders
Diamond is the best conductor of heat and is therefore ideally suited to 21st Century technologies that continually push the boundaries to advance. One problem faced by the electronics industry placing limitations on development has been this issue of heat generation and it’s effect on surrounding components. This is where CVD Diamond Heat Spreaders come in to their own. Previously only a dream due to high cost per mm3 but now a realistic option for modern devices that use electronic chips.
By enquiry only due to the unique and technical nature of the industry.
Quality & Consistency
All of our CVD materials are laser cut to consistent tight tolerances and follow a strict inspection process before despatch to our customers. Special tolerances can be discussed for special applications.
Special Orders + Services
It is possible for us to laser cut special dimensions upon enquiry. In cases where you have more complex requirements that include special tolerances or radiuses, a supplied dxf file makes this a very simple process.
