SCG 500

Grinding of large aspheres and spheres



Today, precise aspheres are an indispensable element in the design of high-aperture-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 manufacturing SCG 500 platform combines the three key product features: double-spindle technology, automated tooling, and on-board measuring technique. The precision grinding technology is expanded by centering, truncating, drilling, and scooping options.
