The military industry requires high, fine and sharp abrasives.
Abrasive tools widely used in military industry, concentrated in the manufacturing, shipbuilding, aerospace, military equipment 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.
Aero engine manufacturing requires abrasive grinding tools. As in grinding, aircraft engine with surface of various valve, sealing surface, working surface of the nozzle, require high luminosity and shape, dimensional accuracy, need to grind to reach requirements.
Aeroengines require good thermal and thermal stability and excellent high temperature mechanical properties. The continuous upgrading of aviation products, especially with the widespread use of various composite materials and difficult-to-machine materials, is gradually improving its processing technology. Currently, more and more advanced grinding tools and technologies such as PCD and PCBN tools and strong grinding are used in the aviation field. In particular, PCD tools have been consistently approved and widely used with superior cutting performance, durability, and high toughness.
For example, the PCD tool for machining engine pistons, the PCD file for machining the piston pin hole of the engine, and the electroplated CBN grinding wheel for machining narrow and deep grooves at the root of the aero engine turbine blade. The ceramic binder CBN grinding wheel is also used in processing aero engines.
