Abstract
Aiming at the problems such as difficult to mearsure and bad consistency of the surfaces in polishing long-focus lens array elements by conventional method, the new way using continuous polishing machine is proposed. According to the theoretical research of the continuous polishing system, the surface of the polishing pad can keep spherical. The workpieces with small curvature spherical surfaces can be polished with the character. The adjusting methods of the polishing pad surface curvature are elaborated. According to the experiments of polishing lens array elements with aperture of 45 mm and curvature radius of 57207 mm in 0.69 m continuous polishing machine, the element surface accuracy and consistency are both better than using conventional oscillating polishing method. At last, the range of the curvature radius that can be polished in the continuous polishing machine is discussed and find that the smaller the polishing pad is, the stronger the ability of polishing spherical surface is. The radius of curvature which is polished in 0.8 m diameter can be as amall as 10 m.
