pcd tools

Cubic boron nitride inserts (CBN Inserts) is a high-performance type of cutting tool material from a polycrystalline mass. CBN is a high hardness, high heat resistance crystal synthesized by boron and nitrogen under high temperature and high pressure. Applications of solid CBN inserts: Processing workpiece: rough and finish machining of the hard steel ,cast iron and hard surface workpiece. Processing materials: ferrous materials possessing hardness from approximately 45 HRC as well as gray cast iron, Cr-chilled cast iron and wear alloys on a cobalt, nickel or iron basis.

Structure and characteristics of pdc diamond dill bit overall structure The  diamond material bit is a one-piece bit. The whole bit has no moving parts, mainly including bit body, crown part, hydraulic structure (including water hole or nozzle, water tank, also known as flow channel, chip chute), diameter protection and cutting edge (tooth). The crown of the diamond drill bit  is the working part of the bit cutting rock. Its surface (working face) is provided with cutting teeth of diamond material and arranged with hydraulic structure. The drill bit body is a steel material body. The upper part is connected to the drill string and the lower part is connected with the crown tire body (the steel crown is integrated with the drill bit body). The hydraulic structure of diamond bits is divided into two categories. A type of natural diamond drill and TSP drill, in which the drilling fluid flows out of the central water hole and disperses across the surface flum...
