The world's hardest material for your tool geometries

Since the early 1990s, CemeCon has been able to three-dimensionally apply the world's hardest material to tool geometries with the CVD diamond coating process. As part of this process, pure diamond grows in polycrystalline form on the substrate surface.

CemeCon is the market leader in CVD diamond coatings

CemeCon produces coatings for a rapidly expanding market in the world's largest diamond coating centre. These are the coating materials of choice for processing abrasive materials like graphite, aluminium-silicon alloys and fibre-reinforced materials for aircraft construction.

In combination with pre-treatment methods customised for carbide and the application in question, the coatings are deposited in either crystalline or nanocrystalline form. Diamond multilayers are also state of the art and are well suited to machining non-ferrous materials. The coatings are applied mainly to shaft tools and inserts made of carbide. We select suitable carbides together with our customers.

Properties of CemeCon diamond coatings:

• Extremely abrasion-resistant
• High level of hardness of 10,000 HV0.05
• High heat conductivity
• No CVD-typical lugs on sharp cutters
• Economic: use of various cutting edges for indexable inserts
• Can be used for high feeds, e.g. during AlSi processing
• No binder phase
