Classification of CBN grinding wheels

2021-08-10 06:16:37

With the continuous emergence of new materials and technologies, the technological progress of the processing industry, for large-scale, high-precision grinding, the hardness of the processed parts is greater than hrc45, and the grinding basically uses CBN grinding wheels. However, CBN grinding wheels need to be trimmed after a period of use. Since CBN is currently a superhard material second only to diamond, ordinary tools cannot be repaired. At this time, the appearance of the CVD diamond roller made the CBN grinding wheel well dressed and widely used in all walks of life.


1. The classification of CBN grinding wheel is based on cubic boron nitride (CBN) abrasives as raw materials, metal powder, resin powder, ceramics, and electroplated metal as binders to make a tool for grinding. CBN grinding wheels can be divided into four types: electroplated CBN grinding wheels, sintered CBN grinding wheels, resin CBN grinding wheels and ceramic bond CBN grinding wheels.


Electroplated CBN grinding wheel: The forming process of the grinding wheel is simple and the production cost is low. The forming is simple, but only one layer of coating cannot be corrected. During the machining process, it is difficult to know when the grinding layer is damaged. It is suitable for small batch processing, grinding and dressing rolls of complex geometric dimensions.


High precision and high precision of CBN grinding wheel. Mainly used for dressing of grinding wheels and processing of large quantities of superhard materials.


Resin CBN grinding wheel: The production process of the grinding wheel is simple and the production cost is low. The shape is simple, but not easy to correct. Used for multi-shape and small batch processing.


Vitrified bond CBN grinding wheel: The vitrified bond CBN grinding wheel has the advantages of strong grinding force, high-speed processing without burning the workpiece, and can be corrected and durable. It is the most ideal high-speed, high-efficiency and high-precision grinding tool.

With the continuous emergence of new materials and new technologies, and with the advancement of processing industry technology, the application range of CBN grinding wheels continues to expand, and the consumption continues to increase. In industrially developed countries, the hardness of high-volume, high-precision grinding parts is higher than hrc45, and they are basically ground with ceramic CBN grinding wheels. It is widely used in the main components of automobiles, such as camshafts, crankshafts, gearbox shafts and gears, bearings and brake pads. Used for precision machining of machine tools, such as the grinding of guide rails, lead screws, motor shafts, and the grinding of printing machine parts. At the same time, for some difficult-to-machine materials and some difficult-to-machine materials (stainless steel, titanium alloy, etc.), CBN grinding wheels are ideal for grinding. CBN grinding wheels can also be used in road rollers, aerospace, military and other industries.
