The final aerodynamic performance and fatigue life of aeroengine blade are determined by the profile accuracy and surface quality.  As the final material removal process of aero-engine blade, grinding directly affects the final mechanical properties and surface state of blade.  

Characteristics of Vitrified CBN grinding wheel Compared with other bonded CBN grinding wheels, vitrified bonded CBN grinding wheels have obvious advantages, wh

PDC-(polycrystalline Diamond Compact） is a kind of composite superhard material sintered under ultra-high pressure and high temperature by using Diamond powder a

Diamond grinding wheel is a better choice for grinding hard alloy, optical glass, ceramics, gem and stone materials with high hardness and high brittleness. However, diamond is not suitable for grinding steel because it is easy to carbonize at 700℃~800℃. The hardness of CBN is slightly inferior to diamond, but it has good thermal stability (can withstand 1300℃~1400℃ high temperature), CBN is not like diamond in high temperature, that is, oxidation and grapitization, and iron group elements chemical inertia, high thermal conductivity, with its production of grinding wheels long life (up to corundum grinding wheel dozens of times to more than 100 times), It is a better choice to replace hardened steel, high speed tool steel, bearing steel, stainless steel, heat resistant steel and titanium alloy and other metal materials with high hardness and toughness.

Silicon nitride ceramics have the characteristics of high strength and high temperature resistance. Among the ceramic materials, its comprehensive mechanical pr
