Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] A method for processing a strip reflector, comprising the following steps:

[0044] 1. DMG milling molding

[0045] 1) Take a rectangular cylindrical blank, and mill the long side adjacent to the surface to be processed. The weight-reducing groove required by the drawing is 13mm long, 6mm wide, and 10mm deep;

[0046] 2) Heat to melt the wax. After waxing the side of the blank opposite to the surface to be processed, turn the surface to be processed upwards, and the reference surface of the blank is close to the limit structure of the tooling. Bond the blank to the tooling and wait for the wax to cool After that, form the blank tooling;

[0047] 3) Install the blank tooling on the workpiece axis of the DMG milling equipment, fix the dial indicator on the Z axis of the milling equipment, position the blank reference plane, control the parallelism within 0.005, ...

Abstract

The invention provides a high-precision processing method for a long-strip reflecting mirror. The method includes the following steps that a semi-finished product is obtained, the reference plane of the semi-finished product is milled through a DMG ultrasonic-wave milling machine, a weight-reduction positioning hole is milled, and through the combination of manual polishing and QED magnetorheological polishing, the to-be-polished optical surface is programmed; optical surface type data is measured, and based on the requirement of a drawing, surface type correction is conducted. According to the high-precision processing method for the long-strip reflecting mirror, the processing efficiency and accuracy of the long-strip reflecting mirror are improved, and the high-precision long-strip reflecting mirror can be processed. The processing difficulty and the detection difficulty are effectively reduced, production of waste products is avoided, the rejection rate of processing is reduced, the process is simple, operation is convenient, and the method has a good application prospect.

Description

technical field [0001] The invention relates to a processing method of a reflecting mirror, in particular to a high-precision processing method of a long reflecting mirror. Background technique [0002] High-precision ultra-smooth surface manufacturing needs to be realized by computer numerical control polishing technology, and this article introduces a precision magnetorheological polishing machine tool. The QED magnetorheological slurry delivery system is a closed recirculation system that keeps the magnetorheological slurry well mixed and constantly monitors and controls many of its attributes, such as slurry flow. Residing in the slurry delivery pump and conduit of the slurry delivery system. The polishing liquid delivery pump is an electromagnetic flow valve through the conduit, and then through the flow meter. From here the slurry is conveyed to a spherical hub, which rotates at about 1–3 m / s. The hub supports a band of polish around its outer surface. The scraper ...
