Grinding of large flats, spheres and aspheres

Introducing the Surfacing Center SCG 600 For large optics in industrial, scientific, and space applications precision grinding is the undisputed manufacturing technology of choice. The Schneider Surfacing Center SCG 600 delivers a new level of quality and accuracy when grinding such large flats and long-radius spheres. The fabricated lenses can have impressive diameters up to 950 mm and even aspheres can be generated with diameters up to 520 mm. The highly integrated SCG 600 platform combines the three key product f ­eatures: double-spindle technology, automated tooling, and on-board...

Solid foundation A very stiff cast-iron base forms the rock-solid foundation for this impressive machine. No less than six axes and three direct drive spindles create the freedom and precision of motion to accomplish the challenging processing tasks. The kinematics has been specifically optimized to process large flats and spheres to very tight tolerances. The modern SINUMERIK 840 Digital controller system enables high precision and excellent dynamics. This state-of-the-art controller drives the quality-defining AC servo drives. Double-spindle technology A special advantage of the SCG 600...
