It features a six-position grinding-wheel spindle station for wheels up to 300mm in diameter (wheel change takes just 2sec) and an integrated wheel-dressing unit.
An optional six-axis Fanuc robot cell equipped with HSK63 loader carousel can accommodate up to 100 tools; it can also include laser marking as an option. In addition, a range of clamping stations (including bespoke systems) can be accommodated for both round tooling and indexable inserts.
