The efficient grinding process of CBN grinding wheels is one of the important technologies of advanced manufacturing. Combined with raw and finishing machining, a high material removal rate can be achieved, such as turning, milling and planning. Materials that are difficult to grind can also be grinded with high performance by this method. This paper introduces the development status and latest progress on high-efficiency abrasive machining technologies with CBN grinding wheel, involving high-speed and ultra-high-speed grinding, fast spot grinding, efficient deep-cut grinding, peristaltic feed deep grinding, heavy-duty grinding and belt grinding. The efficiency and parameter range of these abrasive machining processes are compared. The key technologies for efficient abrasive processing were studied, including grinding wheels, spindles and bearings, grinding machines, coolant supply, installation and positioning of wheels and workpieces, and safety protection, as well as intelligent monitoring and NC grinding. The conclusion is that efficient abrasive processing is a promising technology in the future.
