Metal bonded diamond grinding wheel has excellent performance and wide application, which corresponds to the market demand and the improvement of production requirements, so as to improve its bonding strength and forming, increase its service life and expand its service range.
Superhard-Abrasive wheel made of Diamond or Cubic Boron Nitride (CBN) has been widely used in all aspects of grinding field due to its excellent grinding performance.
A diamond wheel is a Special tool for grinding hard and brittle materials such as In order to give full play to the role of the diamond, it is necessary to increase the holding force of the binder on the diamond and improve the bonding strength of the grinding wheel. Single-layer high-temperature brazing super hard abrasive grinding wheel can overcome the disadvantages of the electroplated grinding wheel.
The chemical metallurgical bond among diamond, binder and metal matrix can be realized, which has a high bonding strength. The bonding layer thickness only needs to be maintained at 20% ~ 30% of the grinding particle height.
High speed and high efficiency grinding with large load firmly hold the abrasive particles so that the exposed height of brazed grinding wheel abrasive particles can reach 70% ~ 80%, so as to increase the chip space, grinding wheel is not easy to plug, the use of abrasive more.
Application scope and application field: it is a special effect tool for grinding hard and brittle materials such as hard alloy, glass, ceramics, and gem. hard alloy, glass, ceramics, and gem. In recent years, with the rapid development of high-speed grinding and ultra-precision grinding technology.
Metal Bond Grinding Wheels- Advantages; 1）The metal binder grinding wheel is characterized by its high bonding strength, good formability and long service life large machining margin, strong control ability to grind particles and good wear resistance.
2）Types of Metal Bond Grinding Wheels; Metal binder wheel can be divided into sintered metal binder wheel, electroplated metal binder wheel.
3）Metal Bond Grinding Wheels-Burning craft and Dressing; More bronze and other metals as a binder, with high-temperature sintering manufacturing, its bonding strength is high, good molding, high-temperature resistance, thermal conductivity and wear resistance, long service life, can bear a greater load.
3）Due to the inevitable shrinkage and deformation of the grinding wheel in the sintering process, the grinding wheel must be shaped before use, but grinding wheel dressing is difficult. At present, the grinding wheel is often used in production to roll
The shaping method is not only time-consuming and laborious in dressing, but also has a lot of diamond particle shedding in the dressing process. The dressing wheel itself consumes a lot and the shaping precision is low.
