Vitrified metal mixed binder diamond grinding wheel manufacturing method

The vitrified bond diamond grinding wheel is made by mixing inorganic materials such as vitrifieds, glass or glass-vitrifieds with synthetic diamond abrasives, and then forming by high-temperature sintering after forming by powder pressing. At the sintering temperature, the binder material softens and a part of the liquid phase appears. The binder wets and wraps the diamond abrasive. A series of physical and chemical changes occur at the interface between the binder and the diamond abrasive, and the bonding agent firmly bonds the diamond abrasive. A grinding tool having a certain shape is formed. However, since the vitrified binder is brittle material and is easily broken, the diamond abrasive is peeled off, resulting in poor grinding effect of the grinding wheel, low strength and poor impact resistance. Therefore, how to realize a diamond grinding wheel with good grinding effect, high strength and good impact resistance is a technical problem to be solved in the industry.

  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
