Machining method for perpendicularity of optical piece

Abstract

The invention discloses a machining method for perpendicularity of an optical piece, and particularly discloses a machining method for perpendicularity of an optical piece with the small datum plane. The machining method comprises the achieving steps that the optical piece with the increased datum plane width is fixed to a 90-degree abutting body in an optical cement manner, the abutting body is then fixed to an optical cement plate, and an S1 face subjected to fine grinding copies perpendicularity of the 90-degree abutting body; secondly, the S1 face is fixed to the optical cement plate through optical instant drying glue, and an S2 face subjected to fine grinding copies perpendicularity of the S1 face and the datum plane; thirdly, the optical piece with the S1 face and the S2 face copying the perpendicularity is cut in a half-and-half manner; and fourthly, the non-cut face of the cut optical piece is fixed to the optical cement plate through the optical instant drying glue, and cut faces are subjected to fine grinding so as to achieve the purpose of perpendicularity copying. The machining method is high in operability, the perpendicularity of the machined optical piece is good, and the machining method is suitable for batched production of enterprises.

Description

technical field [0001] The invention belongs to the field of optical cold processing, and in particular relates to a processing method for perpendicularity of optical parts. Background technique [0002] Among the indicators of optical parts, verticality is a very important indicator; the current commonly used verticality processing method is: fix the reference plane of optical parts to the 90° support body with good verticality by means of optical glue, and then Fix the backing body to the bare plastic board, finely grind the required surface, and copy the verticality of the backing body. However, when the width of the reference plane of the optical element is small, there will be situations where the reference plane cannot be fixed to the 90° support body with optical glue or the strength of the optical glue is insufficient. Contents of the invention [0003] The purpose of the present invention is to provide a method for processing the perpendicularity of optical parts...
