PCD is a synthetically produced, extremely tough, mass of diamond particles developed in tandem, with random orientation in a metallic matrix. It is produced by sintering selected diamond particles at high pressure and high temperatures. Graphite is used as a catalyst, so that PDC crystals are able to develop.
PCD has a high thermal conductivity and good heat dissipation from the cutting area. PCD possesses the highest flexural strength of all cutting materials. PCD is very well adapted for aluminum machining with high Si content or other abrasive filler materials.
Temperature hardness up to approx. 650 °C.
The fields of application are similar to CVD thick film diamond:
Non-ferrous metals such as aluminum, brass, plastics, CFRP, GRP, graphite, titanium, ceramics.
PCD-CVD-CBN boring bars
PCD-CVD end mill
