  MoreSuperhard   materials (PCD diamond and cubic boron nitride) are known for their high hardness, but as industrial teeth, a great many of superhard materials(PCD&PCBN) related products need hole making before they can be used. Such as cutting inserts location hole, PCD diamond scribing wheels’ hole , medical device fluid orifice, water jet nozzle hole, drawing die hole and peeling tools’ hole, other PCD/PCBN wear parts’ hole etc. Our company mainly develops a new making holes’ method for PCD & PCBN materials, and adopts advanced electric processing, laser processing, ultrasonic grinding, honing and other methods to develop different processing technologies for different hole shapes. The hole diameter size can reach the accuracy range of micron meter level and the surface quality of inner hole can achieve the highest mirror effect (Ra0.25).  Cutting inserts hole  It is mainly for machining the locating hole of the solid or compact PCD/PCBN cutting inserts. Generally, it adop
