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

The KRAFT FB Series economically machines large, flat workpieces such as brake discs, flanges, wheels, bearing rings, or drum parts. Four sizes with turning diameters from 1,500 to 3,000 mm and suspended workpiece weight up to 2 tons cover small batch to medium series production.

Available as conventional or CNC version (Siemens, Fanuc, or Fagor controls), optionally with or without tailstock, bed longitudinal or crosswise.
