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 250’s 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. Optionally, the versatile surfacing center can be equipped with a freeform package. Two highly dynamical axes with small moving masses enable high accelerations and processing speeds. 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.
