Numerous HORN tool systems can be equipped with ultra hard cutting materials. These include diamond materials such as PCD, CVD-D and MCD as well as CBN substrates for hard machining.

Ultra-hard cutting materials are used when conventional cutting
materials such as carbide such as carbide no longer offer an
economical machining solution. For example CBN substrates for
hard machining and diamond cutting materials for composite
materials. For the production of high-polish surfaces HORN offers
MCD-tipped tool systems.

PKD-tipped tools

Polycrystalline (PCD) is a synthetically produced substrate of diamond particles in a metallic binder phase. PCD-tipped tools are mainly used in the machining of aluminium alloys, carbide green compacts and composite materials.

CVD-D-tipped tools

The synthetic CVD thick-film diamond is created by chemical coating of a carrier substance from the gas phase. The cutting material is almost pure diamond (99.9 percent) and shows its strengths, for example, in the machining of sintered carbide.

MCD-tipped tools

With MCD-tipped tools, HORN offers the possibility of producing mirror-like surfaces with roughnesses in the nanometre range. This enables a flawless cutting edge on the tool, which can only be realised on monocrystalline diamonds (MCD).
