Abstract
An end face polishing apparatus comprises a jig plate for supporting a workpiece, a polishing member for polishing an end face of the workpiece, and a movable lever connected to the jig plate. A pressurizing section presses the lever to bring the end face of the workpiece into pressure contact with the polishing member. The pressurizing section has a first spring member for biasing the lever in a first direction, a pressurizing head for biasing the lever in a second direction opposite to the first direction, a second spring member for biasing the pressurizing head in the second direction, and a pressure sensor disposed between the pressurizing head and the lever for detecting a pressure applied by the end face of the ferrule onto the polishing member when the lever is pressed by the pressurizing section. A pressurization control section controls the pressure applied by the end face of the workpiece onto the polishing member when the lever is pressed by the pressurizing section.
