High precision 95% alumina ceramic shaft 

High precision 95% alumina ceramic shaft In order to extend the service lifetime of shaft, advanced ceramics are proven and more ideal material for making the component. High purity alumina ceramic in the family is one of most cost performance that exhibits fair abrasive resistance, mechanical strength, self-lubrication characteristics as well as quick heat dissipation advantage, let's see the technical parameters of the ceramic materials as following table. In common case, small-size alumina ceramic shaft is formed by dry pressing, and large-size one is formed by cold isostatic pressing (CIP). The density and mechanical strength of finished ceramic parts would be ensured via these state-of-art forming process. Sometimes, ceramic injection molding is ultilized at our facility in order to achieve the high dimensional accuracy. Most of time, further precision machining is needed, including fine grinding, CNC machining and diamond-like polishing. …
