Versatile machining capabilities including external and internal turning, taper turning, thread cutting (metric, imperial, module, and DP), drilling, broaching, and polishing.
Hardened and precision-ground 350 mm cast iron bed provides outstanding vibration damping and high machining accuracy.
Large Ø105 mm spindle bore with D1-8 spindle nose allows machining of large-diameter shafts and workpieces.
High-performance spindle drive with 7.5/9 kW motor delivers reliable power for demanding cutting operations.
Wide thread-cutting range without changing change gears, saving setup time and improving production flexibility.
3-axis Digital Readout (DRO) enhances positioning accuracy and provides better control over the machining process.

The machine body is manufactured from high-quality cast iron, providing a substantial machine weight of approximately 3,190 kg, ensuring excellent vibration absorption. The headstock is equipped with a reinforced bearing system for smooth and stable operation throughout the spindle speed range of 25–1500 rpm. A centralized feed gearbox, leadscrew, and feed rod enable precise thread cutting as well as automatic longitudinal and cross feeds.
