Diamond grinding wheel is grinding carbide, glass, ceramics, hard and brittle materials, high gem effects tools. In recent years, high-speed grinding with the rapid development of ultra-precision grinding technology, put a higher demand on the wheel, ceramics, resin bonded grinding wheel can not meet the production needs, metal bonded grinding wheel because of its combination of high strength, good formability, long life and other significant characteristics of the production has been widely used. Metal-bonded diamond grinding wheel manufacture in different ways mainly by a sintering, plating two types. In order to give full play to the role of super-hard abrasive, foreign from the early 1990s with a high temperature brazing process development of a new grinding wheel, that single high temperature brazing grinding wheel, this wheel is still in domestic research and development stage. 

 Cubic boron nitride (CBN) grinding wheel for processing a variety of materials the following products: ① High-manganese steel; ② high chromium, nickel, molybdenum alloy steel; ③ chilled cast iron (HS80 ~ 90); ④ all kinds of hardened steel ( HRC55 ~ 65); ⑤ all kinds of cast iron (HB200 ~ 400), etc., and in the domestic auto (gear, flywheel, shaft, bearings and other processing), roll, slurry pump (impeller, volute, guard, jacket, etc. processing), mold, cylinder; ⑥ glass, high hardness, soft and tough materials, gems, solve all walks of life in the high hardness cutting difficult materials, and can improve efficiency, substantial processing time and power savings obtained huge economic benefits. 
 CBN (cubic boron nitride) grinding purposes: 
 CBN abrasive grinding wheels made according to different processing techniques and the different components of the binder can be divided into the following four. Their nature and purpose (refer to mechanical processing purposes) are different. 
 (1) electroplated CBN grinding wheel 
 Wheel molding process is simple, low cost of production. Simple but only one layer forming the coating, can not be amended in the process, difficult to know when to wear layer damage. For small quantities of complex machining and geometry processing and shaping grinding wheel used as a dressing. 
 (2) sintered CBN grinding wheel 
 High hardness and density, processed into high-precision dressing roller, the high cost. Mainly used in the grinding wheel dressing roller and large quantities of super-hard material processing. 
 (3) resin grinding wheel CBN 
 Wheel manufacturing process is simple, low cost of production. Forming a simple but good correction surgery. Shape for many small-batch processing. Such as tool wear and tool processing, and glass processing. 
 (4) vitrified CBN grinding wheel 
 Vitrified CBN grinding wheel has a strong, high-speed processing of the workpiece does not burn, and may be amended and durability, etc., is the ideal high-speed, high efficiency and high precision grinding tools.
