KRAFT FB-15/20/25/30 Facing Lathe – Factory New · 1,500–3,000 mm Face Plate · CNC or Conventional

BRAND NEW KRAFT FB SERIES FACING LATHE — FOR LARGE FACEPLATE WORKPIECES UP TO 2 TONS (OVERHUNG)

The KRAFT FB Series is designed for cost-effective machining of large, flat components such as brake discs, flanges, wheels, bearing rings, or drum parts. Four models cover swing diameters from 1,500 to 3,000 mm and permit overhung workpiece weights up to 2 tons, ideal for single-part and medium batch production.

Available as conventional or CNC models (Siemens, Fanuc, or Fagor), with or without tailstock, and with longitudinal or cross beds.

KEY FEATURES

Heavy-Duty Construction
- Machine bed cast in one piece from MEHANITE, bed width 450 mm, heavily ribbed
- Hardened and stress-relieved bed slideways
- Ensures durable, highly precise machining without deformation

High-Precision Main Spindle — G1 Accuracy Class
- Induction hardened, spindle bore up to 230 mm (option)
- Compact spindle housing, widely ribbed for stability

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

CNC-Ready Ex Works
