Faceplate Lathe KRAFT FB-15/20/25/30, factory new · 1500-3000 mm faceplate · CNC or conventional

FACTORY NEW KRAFT FB SERIES FACEPLATE LATHE — FOR LARGE FACEPLATE WORKPIECES UP TO 2 TONS

The KRAFT FB Series is designed for the efficient machining of large, flat workpieces such as brake discs, flanges, wheels, bearing rings, or drum components. Four machine sizes with turning diameters from 1,500 to 3,000 mm and workpiece weights up to 2 t (unsupported) cover single part production through to medium batch sizes.

Available as conventional or CNC version (Siemens, Fanuc, or Fagor), optionally with or without tailstock, bed in longitudinal or cross orientation.

KEY FEATURES

Robust Construction
- Machine bed made from a single piece of MEHANITE cast iron, 450 mm bed width, heavily ribbed
- Hardened bed ways, stress-relieved annealed
- Ensures long-term, high-precision operation without distortion

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

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

CNC-ready from the Factory
- X/Z servo motors from Fanuc or Siemens
- Ball screws X: Ø25 P5 C3, Z: Ø40 P10 C5
- Rapid traverse X/Z: 6/8 m/min

Machining of Unsupported Workpieces — The Faceplate Lathe Advantage
- Workpieces clamped directly on the spindle head, without tailstock
- Ideal for flat, disc-shaped components with large diameters

OPTIONS

CNC Siemens/Fanuc/Fagor · constant cutting speed · PARAT tool holder · C-axis + driven tools/milling unit · tailstock · spindle bore Ø 230 mm · spindle motor 29 kW
