## Study notes

- Available as a six-spindle or double three-spindle machine; the main spindle group uses six fluid-cooled motorized spindles.
- Main spindle duty ratings: 20 kW and 88 Nm at 100% duty; 30 kW and 130 Nm at 25% duty.
- Swiveling synchronous spindles: up to 1 or 2, 52 mm bar capacity, 6,000 rpm max, 5.7/7.2 kW at 100%/40%, 18/23 Nm at 100%/40%, Z travel 132 mm, 3/6 backworking tools.
- Tool slide travels: X 100 mm, Y 56 mm, Z 180 mm; up to 12 tools.
- Backworking slide: up to 1 or 2 slides, X travel 82 mm, 3 tools.
- Control is Siemens S840D sl with iXpanel i4.0 ready and an 18.5-inch multi-touch screen.
- Connecting power is 94-127 kW; long-version dimensions are 4,030 x 2,232 x 3,129 mm.
- Rear-end machining allows up to 6 tools per swiveling synchronous spindle; the swing arm is locked by a three-piece Hirth coupling in the machining position.
- Machining options include side milling with C-axis, end milling with Y-axis, plunge milling, gear hobbing, and elliptical deburring.
- Robot handling can load and unload all six spindle positions with a double gripper; preshaped, forged or extruded parts up to approx. 125 mm can be machined.
- The swivel disk provides a standardized mechanical and electrical interface to peripheral handling; the system is closed to limit oil discharge.
