FACTORY-NEW KRAFT FB SERIES FACING LATHE — FOR LARGE FACEPLATE WORKPIECES UP TO 2 T FLOATING

The KRAFT FB Series offers efficient machining of large, flat workpieces such as brake discs, flanges, wheels, bearing rings, or drum parts. Four model sizes with turning diameters from 1,500 to 3,000 mm and floating workpiece capacity up to 2 t cover requirements from single-part to medium-series production.

Available as conventional or CNC version (Siemens, Fanuc, or Fagor control), with or without tailstock, longitudinal or cross bed options.

KEY FEATURES

Robust Construction
- One-piece machine bed made of MEHANITE cast iron, 450 mm bed width, with heavy ribbing
- Hardened bed guideways, stress-relieved
- Ensures long-term, high-precision operation without distortion

High-Precision Main Spindle — Accuracy Class G1
- Induction-hardened, spindle bore up to 230 mm (option)
- Compact spindle headstock with large cross ribs

Powerful Drive
- Spindle motor 22 kW (optional 29 kW), up to 600 rpm, high torque
- Infinitely variable spindle speed as standard

Ready for CNC from Factory
