Saint-Gobain PCD and CVD tools: Diamond tools for precision

PCD and CVD tools are among the hardest cutting materials for machining. Their high wear resistance and precision make them the ideal solution for demanding machining tasks in industry and manufacturing. Saint-Gobain Diamantwerkzeuge GmbH in Norderstedt has been developing customized PCD (polycrystalline diamond) and CVD (chemical vapour deposition) cutting materials for many years. Compared to conventional materials such as carbide, they offer a longer service life, higher cutting speed and excellent surface quality. Both cutting materials are particularly suitable for non-ferrous metals, aluminum alloys, composite materials or the green machining of ceramics. PCD is produced by sintering diamond particles with a binding matrix and sintered directly onto a carbide carrier. The grain size is decisive for the result: Saint-Gobain offers six basic sizes from very fine (~1 μm) for high-precision surfaces to coarse (~25 μm) for rough machining. CVD, on the other hand, is deposited under vacuum as a pure diamond layer and offers even higher wear resistance. Different coating thicknesses from 0.3 to 1.5 mm enable use both in cutting tools and as wear protection.

PCD and CVD tools - diamond cutting materials for every challenge

The range of applications is diverse: from machining acrylic glass for optical applications to aluminum components in automotive engineering and composite materials in wind power. PCD blades for stripping cables and centering tips also benefit from the special properties of diamond cutting materials. In addition, PCD and CVD coatings extend the service life of grinding and measuring technology, thereby increasing productivity. With customized geometries, grit sizes and coating thicknesses, Saint-Gobain diamond tools provide solutions that are clearly superior to conventional cutting materials in terms of precision, efficiency and service life.
