| Abstract: |
| In this paper, the structural characteristics and technological difficulties of the large-sized elliptical concave surface mirror were studied and analyzed. The processing scheme was designed and the technical problems in the mechanical polishing process were solved. A concave mirror with a surface roughness of 0.606μm was developed. With the detection of three coordinate, it was found that the size error of Z axis direction of the reflection surface was in the rang of ±0.05mm, which satisfied the technical requirements of concave mirror. |
