Embodiment Construction

[0014] The present invention will be further described below in combination with specific embodiments.

[0015] The profile of the eccentric meniscus mirror to be processed in this embodiment is as follows figure 1 , 2 as shown,

[0016] The processing method of the eccentric meniscus cylindrical mirror of this embodiment includes the following steps: 1) Processing the product into a cuboid of a specified size by milling and grinding the blank, and processing the side pads and low Pad and backing body; 2) Heat to melt the wax, stick two pieces of products on both sides of the backing body 1, and then stick a side pad on the other side of the product, wait for the wax to cool down, and complete the first loading, such as image 3 ;3) Use the milling wheel to mill the concave surface of the product, then use a cast iron disc with silicon carbide sand to finely grind the concave surface, and then use asphalt polishing powder to polish the concave surface. During the processing ...

Abstract

The invention discloses a machining method for an eccentric crescent cylindrical mirror. The method comprises the steps that blank and cushion material taking is conducted, and a blank and cushion materials are bonded through wax; concave face milling grinding, fine grinding and polishing are conducted; the blank and the cushion materials are heated to be separated, and the blank and new cushion materials are bonded again through wax; convex face milling grinding, fine grinding and polishing are conducted; and heating is conducted, a product is taken out, and the eccentric crescent cylindrical mirror can be obtained. According to the machining method, through strict control over the cushion material size and the center thickness and eccentric volume of the cylinder face obtained after fine grinding, and accordingly the high-precision eccentric crescent cylindrical mirror can be machined. Through the manner that the cushion materials are bonded and fed to discs to be machined, the machining difficulty and detection difficulty are effectively lowered, and the machining efficiency and the product qualification rate are improved; and the beneficial effects that the technology is simple, and operation is convenient are achieved.

Description

technical field [0001] The invention belongs to the field of optical cold processing, and specifically refers to a processing method of an eccentric meniscus cylindrical mirror. Background technique [0002] Eccentric meniscus cylindrical lens, cylindrical lens is a non-axisymmetric special aspheric lens, which can provide the best optical power in one dimension, and is equal to a plane in the other dimension orthogonal to it. This feature makes it in Some special fields have obtained important applications; due to equipment design and assembly reasons, eccentric meniscus cylindrical mirrors are required, that is, eccentric cylindrical mirrors with one concave surface and the other convex surface. Month and requires high precision, so processing is more difficult. Contents of the invention [0003] The object of the present invention is to provide a processing method for an eccentric meniscus cylindrical mirror, which solves the problem of low processing accuracy of the e...
