Abstract
The aspheric optical parts can get good image quality, good optical system correction of various aberrations, to improve the image quality, and improve the system ability to identify it to one or several non-spherical spherical optical parts unparalleledparts instead of a number of spherical parts, thus simplifying the instrument structure, reduce costs and reduce instrument weight. It’s widely used in many realms, such as national defense, machine chemical and aviation. It’s very useful to develop the grinding theory and important practical significance to study the high precision grinding methods about the optical glass aspheric surface parts.
This article discussed in the ultra-precision grinder, C operation program,and the aspheric surface optics parts’ grinding craft. The center height micro-adjusting mechanism and the drive system. In the process of the research, we analysis it detailed that the main factor influence the process precision of the parts, and make something to solve it, especially for the precision grinding equipments, and analysis it simplify for the precision machine tool for aspheric surface optics parts and the servo-control system and the other technology.
Key words: the aspheric surface; ultra-precision machining; the micro-adjusting mechanism; diamond wheel
