I will assume that you have made mirrors before and thus wont describe the basic processes of grinding and polishing glass or testing an optical figure by means of a knife edge or Ronchi tester. Many books exist which detail these processes my personal favorite is Jean Texereaus How to Make a Telescope Willmann-Bell 1984 .
Introducing the Surfacing Center SCG 250 Working with larger optics in the 250 mm range you are confronted with various geometries and demanding specifications that require sophisticated grinding solutions.
The SCG 250s unique mechanical design combines ideal axis configurations for excellent grinding of large spherical aspherical and freeform optics in one machine. Its innovative kinematics and spindle setup allow for both cup and peripheral wheel grinding in one process cycle resulting in superb form accuracy and minimized surface roughness.
The optional packages include fast automation and sophisticated in-process measurement technology for higher productivity and process stability.
Innovative frame concept The SCG 250 has been designed with your requirements for perfect grinding in mind. The new frame concept is the basis for completely independent vertical and horizontal spindle arrangements as well as tool configurations. It unites perfect preconditions for the very different grinding tasks like spherical and aspherical machining in one innovative mechanical design. An independent placement of the working positions allows high flexibility in tool size and process design with virtually no limits.

Advanced spindle technology The spherical version of the SCG 250 comes with up to three independent tool spindles offering higher flexibility in defining the grinding steps and corresponding grain sizes of the tools.
The version S21 enables automated multistep processing. One spindle does the rough grinding including centering and beveling. A second spindle takes care of the fine grinding.
With the version S31 the grinding is brought to the finest level. The additional third tool spindle meets the highest quality requirements. It also increases your flexibility in small batch processing reducing the need for disruptive tool changes.

Rough Grinding . Once you have the back of the mirror ground flat through 220 and the face reasonably flat youre ready to start roughing the curve into the mirror. I recommend 60 carborundum for rough grinding. By the way as in all optical work be sure that you always maintain bevel on the edge of the mirror throughout grinding.
However all these data will change as the grinding wheel becomes blunt. To reduce the work on the selection of grinding parameters and keep the grinding process stable a new force-controlled grinding strategy for large optical grinding machine on brittle material is proposed.
