The wheelheads are independently CNC controlled, using servomotor ball screws.
The entire assembly is mounted on a thermally stable natural granite base.
The grinder allows workpieces up to 250mm tall, offers a 300mm swing, and 350mm X-axis travel. A
variety of options are available such as autoloaders and gauging.
