The fiber optic ferrule assembly generally comprises a ferrule and an optical fiber inserted into an internal hole of the ferrule. The optical fiber can be fixed within the internal hole of the ferrule by adhesive. After fixing the optical fiber within the internal hole of the ferrule, a front end surface of the whole fiber optic ferrule assembly needs to be ground and polished precisely so as to achieve predetermined optical performance.
In prior art, when the front end surface of the fiber optic ferrule assembly is polished, generally, a plurality of fiber optic ferrule assemblies are clamped and fixed on a carrier. Then, a pressing mechanism presses a pressing head so as to press the carrier against a positioning component. In prior art, the carrier is generally formed as circle-shaped or square-shaped, and the pressing head presses the carrier at a central portion thereof.
