Right-angle prism edge grinding device and method

The invention relates to the technical field of optical prism machining, in particular to a right-angle prism edge grinding device and method.The right-angle prism edge grinding device comprises a mounting base, two connecting frames are arranged above the mounting base, and two containing shells are arranged between the two connecting frames up and down; the ends, away from each other, of the two containing shells are each provided with a first machining plane, and the first machining planes are each provided with a first penetrating groove. The right-angle prism is wrapped and positioned through moving wrapping of the two containing shells, the stability of the right-angle prism in the edge grinding process is effectively improved, and the straight corner and the right side corner of the right-angle prism extend out along the corresponding first penetrating groove and the second penetrating groove correspondingly; and in the process of polishing the extended corners, through blocking of the first machining
