Polycrystalline Diamond is a diamond combo produced by diamond sintered with bond under high temperature and high pressure; it has very high wearability and high thermal stability.
The polycrystalline diamonds include TSP Series for drilling bits and PCD series for genuine diamond polished.
TSP is an unbacked polycrystalline diamond product,which is manufactured by the same ultra-high pressure and high temperature techniques as other PCD products.It is thermally stable up to 1200°C for its binder is chemically insert and has a similar coefficient of thermal expansion like that of diamond.It is suitable for mining bits and oil drilling bits.
PCDSeries has lower wearability than TSP Series. Compared to genuine diamond, it not only has much high grinding efficiency, but the price is much lower. Therefore, it is the first choice for demand processing nowadays. The engineers of Sanhe corp. can control the wearability of polycrystalline diamond accurately for different industrial purposes.
