Method and tool for polishing inner and outer walls of cylindrical optical part

Abstract

The invention provides a tool and method for polishing the inner and outer walls of a cylindrical optical part. The tool and method are used for solving the problem that in the prior art, a cylindrical optical part cannot be mechanically polished. The polishing tool comprises a power connector, a base, a lantern ring and a gland. The base and the gland are both round in basic shape. The part is fixed through the base; when the outer wall is polished, the part is limited and stabilized through the gland; and when the inner wall is polished, the part is limited and stabilized through the lanternring. According to the tool and method for polishing the inner and outer walls of the cylindrical optical part, the inner wall and the outer wall of the optical part are polished through one-time positioning; when the inner wall is polished, the lantern ring is used for assisting in fixing the part; and when the outer wall is polished, the gland is used for assisting the fixing force of the base.The gland and the base are used respectively to guarantee the stability of the part in the polishing process, so that the mechanical polishing of the inner wall and the outer wall of the cylindricaloptical part is achieved, the polishing efficiency is improved, and meanwhile the polishing precision and the shape and position precision of the part are guaranteed.

Description

technical field [0001] The invention belongs to the field of optical parts processing, and in particular relates to a polishing method and tooling for the inner and outer walls of a circular cylindrical optical part. Background technique [0002] A circular cylinder is a common shape of optical parts. Optical parts have relatively high precision requirements, and usually need to be ground and polished before they can be assembled. At present, when modern mechanical means are used to perform chemical mechanical polishing on optical parts, at least the X, Z, B, and C axes of the tooling equipment holding the parts are used to link the parts, and the processing efficiency is high. However, most optical parts that can be mechanically polished are Flat, spherical, aspheric and other forms. [0003] Due to the particularity of the shape of the toroidal cylinder and the inner and outer walls of the toroidal cylinder, mechanically assisted manual polishing is usually used in the p...
