It carries a 21-inch chuck on an A1-15 spindle nose with a 181 mm (7.1 in) spindle through hole and 165.5 mm bar capacity. The geared main spindle runs to 1,500 rpm and is driven by a 45 kW (60.3 hp) 30-minute / 37 kW (49.6 hp) continuous motor, producing up to 2,957 N·m of torque. Swing over bed is 900 mm (35.4 in); maximum turning diameter is 650 mm (25.6 in) and maximum turning length on the long bed is 2,001 mm (78.8 in). Z-axis travel is 2,155 mm and X-axis travel is 362 mm. The 12-station turret takes 25 mm square OD tools (32 mm optional) and 60 mm boring bars, and its rotary tools run to 4,000 rpm with a 23 kW peak / 7.5 kW continuous drive; the C-axis indexes in 0.001-degree steps.
