Grinding of large aspheres and spheres

Introducing the Surfacing Center SCG 500 Today, precise aspheres are an indispensable element in the design of highaperture-ratio, compact objectives for a wide range of industrial applications. When large aspherics are needed, precision grinding is the undisputed manufacturing technology of choice. The SCHNEIDER aspheric grinding machine SCG 500, delivers a new level of grinding large aspheres with up to a diameter of 500 millimeters with high quality and form accuracy. In an unprecedented way, the highly integrated SCG 500 platform combines the three key product features: double-spindle technology,...

The unique combination of these features ensures a high processing flexibility for the production of the easiest to the most complex parts. Not only aspheres, but also spheres, flats, prisms and other special geometries can be manufactured on the SCG 500. High utilization of the machine is guaranteed. Solid foundation A very stiff cast iron base forms the rocksolid 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...
