SPECIAL PCD AND PCBN TOOLS


Special sinthetyc diamond (PCD) and cubic boron nitride (PCBN) tools. Used for turning as a knife or as inserts, for hard materials

SPECIAL PCD AND PCBN TOOLS


MACHINING WITH PCD

This tool is a plate of synthetic diamond compacted on a tungsten carbide substrate. Synthetic diamond’s main characteristic is that, unlike natural diamond, it does not have a defined crystal structure.
Therefore, and as it is polycrystalline, it is more resistant to breakage by impact and it is impossible to damage by vibration.
It never breaks anywhere but the work area and, even when this happens, it is only by accident. Use of these tools is limited to direct machining of non-ferrous materials (brass, bronze, aluminium, copper, gold, silver, etc.), which withstand non-continuous cutting well.
They can be mounted with the geometry and substrate that the work to
be carried out requires.
To achieve the most demanding finishes, we can supply plates with various micro-grain sizes in the compacted layer.
Moreover, these plates are dressable.

MACHINING WITH PCBN

This tool is a plate of cubic boron nitride compacted on a tungsten carbide substrate. Its fundamental characteristic is that it can be used to machine treated steels and special alloys with hardnesses greater than 55 HRC (up to 70 HRC) without the need for grinding if the operation does not require it. Moreover, it can be used at extremely high cutting velocities and, as it chips the material, it does not cause significant heating in the machined part.
Use is not recommended where carbide can be employed. It performs flawlessly on high-speed tool steels.
Conversely, it does not withstand non-continuous cutting well.
These tools can be mounted with the geometry and substrate that the work to be carried out requires.
Moreover, these plates are dressable.
