Chip-Cutting Machining - PCDThis is a plate of synthetic diamond compacted on a tungsten carbide substrate. This tool's main characteristic is that synthetic diamond, unlike natural diamond, does not have a defined crystal structure. Therefore, and as it is polycrystalline, it is more resistant to breakage by impact and is impossible to damage by vibration. It never breaks anywhere but the work area and, even when this happens, it is only by accident. As an example, when turning small armatures (approx Ø 40), a single cutter can be used to machine more than 200,000 units whilst achieving the required tolerances and roughness. This would be impossible to achieve with a natural diamond cutter, especially as in this case cutting is interrupted. Use of these tools is limited to direct machining of non-ferrous materials (brass, bronze, aluminium, copper, gold, silver, etc.), which withstand interrupted 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. This is a plate of cubic boron nitride compacted on a tungsten carbide substrate. The fundamental characteristic of this tool is that it can be used to machine treated steels and special alloys with a hardness greater than 55 HRC (up to 70 HRC) without the need for grinding if the operation does not require it. 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. Its use is not recommended where tungsten carbide could be employed, but it can provide major time savings if grinding does not have to be performed on parts on which a lot of material needs to be removed. It performs excellently on high-speed tool steels. Conversely, it does not withstand interrupted 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.
