Two-spindle machine for increased Precision
In addition to the very small footprint and 4-station wheel changer, the Eclipse Grinding Center features a 2nd grinding spindle for finishing the final tool-geometry. Since the spindle 2 wheel package is not being changed during the grinding cycle, there will not be any random inaccuracies. The grinding spindle 1 has an automatic (or manual) wheel changer and is primarily dedicated for roughing operations.
The workpiece spindle has dual functionality: it can be used both as a positioning axis and a free-turning spindle (used when cylindrical grinding or dressing). The B axis can be equipped with worm-gear or direct drive. The X-Z axes are backlash-free as a result of hydraulic compensation.
