Abrasive tool widely used in military industry, concentrated in the manufacturing, shipbuilding, aerospace, military equipments gun manufacture and so on each link of weapons and equipment manufacturing, its application range is wide, not only and a high content of science and technology, the requirement of accuracy is high, which determine the abrasives used in military industry, must be high, refined, sharp.

Application of abrasives in aerospace equipment

China is after the United States, Britain, Russia, France, the fifth country has the ability to develop its own aircraft engine. The engine is undoubtedly the "heart" of aerospace equipment and the source of power. The manufacture of aero - engine is inseparable from abrasive and grinding. For example, in the aspect of grinding, the matching surface, sealing surface and working surface of jet nozzle of various valves of the aeroengine require high luminosity and shape and dimension accuracy, which need to be ground to meet the requirements.

Aeroengines require good thermal stability, thermal stiffness and excellent mechanical properties at high temperature. With the continuous upgrading of aviation products, especially with the widespread use of various composite materials and refractory materials, its processing technology is gradually improving. At present, more and more advanced grinding tools and technologies such as PCD and PCBN are used in the field of aviation. PCD tools, in particular, have been widely used for their superior cutting performance, durability and toughness. For example, PCD tool for machining engine piston, PCD boring tool for fine boring and boring of engine piston pin hole, and electroplated CBN grinding wheel with narrow deep groove at the root of engine turbine blade. Ceramic bond CBN grinding wheel, also used in the processing of aircraft engines.
