With high hardness, good wear resistance of composite materials shares characteristics of diamond and tungsten carbide substrate composition. Over the use of kerosene tricone biting, geological prospecting , coal tricone biting and machining the tricone bit stuff and other industries. PDC tricone biting category : soft to medium-hard aggregate for geological tricone biting , with high toughness and heat resistance to fight chaos , heat temperatures up to 750 ℃ ( two minutes ) and a variety of such products available in the three-dimensional slot surface -linked type , and according to the user the necessary plans groove, grinding, polishing , chamfering , etc., can supply the product special shape. Machine tool class PDC : together for nonmetallic , non-ferrous metals and the rest of the cutting and processing of metal cutting high hardness alloys, wood, ceramics , etc., have a high hardness and wear resistance, high cutting precision , while according to the user necessary , the product development process square, triangle , fan and other shapes can be used for the construction of wearable devices, tricone bit, tricone bit the top and teeth (with a spherical shape, taper ) and so on .
