Diamond tools have excellent adaptability in the processing of non-ferrous metals and wear-resistant materials. When using diamond tools, there have two options: one is 

polycrystalline diamond (PCD), and the other is the newer chemical vapor deposition (CVD) diamond.

PCD tools are most suitable for machining aluminum and other non-ferrous alloys with better toughness (such as copper, brass, and bronze), as well as highly abrasive 

composites (such as graphite, carbon-carbon materials, carbonized phenolics, fiberglass, and porous Sealing material). CVD diamond tools is better at finishing, semi-finishing

and continuous turning, because it has excellent wear resistance and high hardness, which can process more precise workpieces.

PCD and CVD diamond can be used in many of the same processing areas. PCD is more suitable for roughing and processing where high fracture toughness is required. 

CVD diamond is better at finishing, semi-finishing and continuous turning, which can produce more precise workpieces. In machining that requires complex tool geometries, 

CVD diamond is also the best choice, while PCD tools can only be made into simpler tool shapes.

LINKUT could help you find the best choice for the diamond tools based on your detail application and requirements, no matter for the graphite machining, or other applications.
