Ceramic Ring For Industry Smart Wear


Ceramic ring is the component of intelligent electronic ring.Because ceramic ring by zirconia, alumina and other advanced ceramic materials through isostatic pressure, sintering, molding and other processes.Therefore, ceramic ring has excellent ceramic properties, such as rockwell hardness of hra80-90, hardness is second only to diamond, far more than the wear resistance of wear-resisting steel and stainless steel, but also has good mechanical strength and corrosion resistance, volume mass is relatively small compared with other ceramic materials.
 
Precision machining dimension of ceramic ring can be up to + / - 0.001mm, the narrowest machining groove width 0.1 x 100mm, linear tolerance up to 0.001mm, cylindricity up to 0.004mm.
